Preface

The General Census on Population and Housing is one of three General Censuses specified in the Statistics Code, with a 10-year execution cycle in the years ending in 9. The General Census on Population and Housing is a primary and reliable source of information on the population situation, demographics and housing status of the population in order to meet the objectives of compiling and developing the indicators in the System of National Statistical Indicators specified in the Statistics Code. It is also a source of information to serve the Party, National Assembly and the Government in assessing the situation, developing strategies and policies related to the people and development policies of the country.

On June 26, 2018, the Prime Minister issued Decision No. 772/QD-TTg on organizing the General Census on Population and Housing at 0:00 on April 1, 2019; this is the 5th General Census on Population and Housing in Vietnam since the country reunification.
The 2019 General Census on Population and Housing is the first General Census to apply information and communication technology in all stages of the General Census, from network preparation, information collection, data check and approval, data processing to announcement of the results of the General Census. In particular, mobile devices are used to collect information in the census areas.

Information of the 2019 General Census on Population and Housing is collected from two types of census form: complete census form and sample census form. The sample census form consists of 65 questions designed to collect information from about 10% of the country's population about the population situation, housing, birth history of women and the deceased.

To guide the census team leaders and enumerators to perform their assigned tasks in accordance with the provisions of the 2019 General Census on Population and Housing, to collect information on the sample census form with the correct scope such that information is complete and accurately reflects the actual situation of households, the Steering Committee for the General Census on Population and Housing has compiled the Manual on Operation and Application of CAPI in General Census on Population and Housing at 0:00 on April 1, 2019 (Sample survey form). This Manual contains the following main contents:

The Steering Committee for the General Census on Population and Housing is pleased to introduce the book ''Manual on Operation and Application of CAPI in General Census on Population and Housing at 0:00 on April 1, 2019 (Sample census form)" to officials, Steering Committee for the General Census on Population and Housing at all levels, supervisors, census team leaders and enumerators for uniform implementation nationwide.

Part II: General provisions of the 2019 General Census on Population and Housing

I. Time of census
The time of census is 0:00 on April 1, 2019.

During the census period, no matter what date or time they visit the household to interview, DTV must take the time benchmark as 0:00 on April 1, 2019 (12 o'clock at night on March 31, 2019 to be exact) to determine the number of NKTTTT in the household and personal information of NKTTTT. For questions about migration circumstances, employment, and mortality of the population, DTV must rely on the period of information collection to determine the full range of events.

II. Period of census
The period of census is the time to collect information in the area, about 25 days (including travel time), starting from April 1, 2019 to the end of April 25, 2019.
Commune level BCD organizes human resources to conduct census on vagrants, the homeless and people making a living on the water without home on the shore, without a port of origin currently present within the commune, ward or town on the first census day (April 1, 2019).

III. Methods of information collection
TDT 2019 uses two methods of information collection: face-to-face interview and households self-report information on the website of TDT 2019.

IV. Census subject
DTDT of TDT 2019 includes:

V. Census unit, housing unit, place of residence and information provider

1. Census unit
The census unit is the household. Household includes one person eating and residing separately or a group of people eating and residing together. For households with 2 or more people, members of the household may or may not have a shared revenue and expenditure fund; they may or may not be related by blood, marriage or adoption; or a combination of both.

According to the concept of a household, domestic helpers, tenants, and unrelated people are also considered members of the household (also known as NKTTTT in the household) if they often sleep and eat together in the house/apartment/dwelling of the household for 6 months or more up to the time of the census.

A household usually uses all or part of a house/apartment, but there are also households living in tents, shacks, camps, motels, hotels, collective houses, barracks, dormitories, etc., or no housing.

[p.21]

The regulations on household identification for some special cases are as follows:

In special cases, when children (or elderly people) are economically dependent on their parents (or children) but sleep in nearby house(s)/apartment(s)/dwelling(s) (household with multiple residences), the children (or elderly people) are counted as members of the household of their parents (or children) and censused together in 1 household.

2. Housing unit
Housing is a building that includes 3 parts: floor, roof, wall and used for living.

A housing unit is a separately structured and independent building whereby it is constructed, modified or arranged, and used as the residence for 1 or more households. It can be a block of houses/house/apartment/room. Note: In the case of a raft house on a river or lake, if it has all 3 parts: floor, roof, wall as defined above, it is counted as a housing unit. A part of 1 house (room or group of rooms) can also be a housing unit if it satisfies the following 2 conditions: (i) Separation: A part of the house must have facilities for sleeping, cooking and the occupants must be separated from other households in the house by a wall or partition; (ii) Direct entrance: It is possible to directly enter a part of the house from the outside. In other words, the occupants can go in and out of the house without having to go through anyone's residence.

[p.22]

3. Place of residence
Place of residence is a place people use to reside (eat, sleep, live), it can be 1 house/apartment, however, it can also be places that are not houses/apartments but renovated or arranged to be a place of residence or to be used as places of residence even though it is not actually intended to be a place of residence, such as: wagon, train car, area under a bridge, cave, grotto, etc.

4. Information provider
The head of the household (or someone knowledgeable about members of the household) is the person who provides information about NKTTTT, the deceased, housing and living conditions of the household. For information about the member of the household that the head or representative of the household is unsure of, DTV interviews the member of the household face-to-face to collect this information.

For employment information, DTV must interview DTDT face-to-face who are 15 years old or older; for information on birth history and reproductive health, DTV must interview DTDT face-to-face who are female adolescents aged 10-14 and women aged 15-49.

VI. Census area, commune/ward background map and household list

1. Census area
DBDT is a residential area with clear or relatively clear boundaries; basically village, hamlet, neighborhood, population group, quarter, subdivision (in short, hamlet/population group). In each commune, ward, and town (abbreviated as commune/ward), there are many DBDT, and the boundaries of DBDT are combined into a map of the commune/ward. The average size of DBDT in the country is about 120 households/area. DBDT is shown on the background map of the commune/ward.

2. Commune/ward background map and household list
The background map of the commune/ward shows the scope and boundaries of the hamlets/population groups and DBDT in that commune/ward.

The household list is a list of households and some information about households in 1 specific DBDT, including: information on the ordinal number of the house/apartment/dwelling in which the household is residing, the ordinal number of the household, the total number of NKTTTT of the household, the number of female NKTTTT of the household; information about whether the household registered to self-report information on Webform; mobile phone number and email address (email) of the household (for households registering for Webform).

[p.23]

VII. Actual permanent residents in the household
NKTTTT in the household are those who have actually eaten and resided at the household for 6 months or more by the time of the census and those who have just moved in for less than 6 months but intend to eat and reside permanently in the household, newborns born before the time of the census, and those who are temporarily away regardless of whether they have permanent household registration.

1. Actual permanent residents in the household
The following cases are identified as NKTTTT in the household:

(1) The people who have actually eaten and resided at the household on a regular basis for 6 months or more up to the time of the census regardless of whether they have permanent household registration; those who already have a moving notice (notice of call to military service, enrollment letter, employment offer, job transfer, etc.) but at the time of the census have not yet left the household to move to a new place of residence.

Some people have lived in the household for 6 months or more up to the time of the census but are not counted as NKTTTT in the household, including:

Notes:

(2) People who have just moved in the household for less than 6 months but intend to eat and reside permanently in the household for a long time, including:

Notes:

(3) People who have been regularly eating and residing at the household for a long time but were temporarily away at the time of the census, including:

Notes: In border districts, some ethnic minorities have the custom of nomadism or travel to other countries for seasonal work for less than 6 months and then return to Vietnam. Those are counted as NKTTTT in the household and temporarily absent.

Some special cases when identifying NKTTTT in the household:

Notes when identifying people on the payroll of the police and military:

DTV needs to ask carefully about the people on the payroll of the police or military who are living in the household in order to properly identify NKTTTT in the household. Therein:

[p.27]

2. People who are not actual permanent residents in the household
The following cases are not NKTTTT in the household:

(1) People not living in the household at the time of the census, including:

(2) People living in the household at the time of the census, including:

[p.29]

VIII. Special demographics
Special demographics are people who live in special DBDT, including:

[p.35]

Part IV: Instructions on how to question, record cover information, and identify actual permanent residents of the household

I. Introduction of the census form
The content of TDT 2019 is designed on 2 types of census forms: Complete census form (also known as the short form) and Sample census form (also known as the long form).

1. Short form
The short form contains basic information about the population and housing. In addition to the questions to confirm NKTTTT in the household, the short form includes identifying information and 22 non-consecutively numbered questions, specifically as follows:

2. Long form
The long form includes the information in the short form and also adds some questions about the birth history of women and the employment situation of a part of the population assigned the sample census form. Therefore, households assigned the sample census form to answer the long form will not have to answer the short form.

In addition to the questions to identify NKTTTT in the household, the long form includes identifying information and 65 questions consecutively numbered from 1 to 65, specifically as follows:

[p.36]

II. How to record cover information of the census form

1. Identifying information
1.1. For a paper form
DTV copies the identifying information available on the Household list (Form No. 03B/BCDTW in Appendix 6) to the census form, specifically as follows:

For households that used 2 or more sets of forms, the information belonging to the identification part from the second set of forms onward shall be recorded the same as the first set of forms.

1.2. For electronic form
When DTV logs into the program, the identifying information of the households in the assigned DBDT will automatically be transferred from the Household list to the census form. DTV does not have to copy information from the Household list as instructed for the paper form.

[p.37]

However, among the information that is automatically transferred from the Household list, the information about "the full name of the head" may need to be modified due to a new household moving in (the previous household has moved out) or the household remaining but the information about the head of the household changes compared to the Household list. In this case, DTV interviews to record the actual information of the household at the time of the census. For new households just moving to DBDT and have not been named in the Household list, DTV shall add a new household according to the instructions in the Manual for the electronic form.

2. Information on census results
2.1. For a paper form
The enumerator records the information on census results when completing the interview at the household. Specifically as follows:

The form is designed to have enough space for households with a maximum of 6 people, each person is recorded in 1 column. For households that used 2 or more sets of forms, from the second set of forms onwards, DTV records the ordinal numbers of the members of the household in a continuous natural order, for example in the second set of forms, the ordinal numbers of the members of the household are: 7, 8, 9, 10, etc.

In case for some reason DTV has to cancel 01 (or more) column (person), DTV must correct the ordinal number of each person (before the line of Question 1 in the census form) so that the ordinal numbers of the members are continuous.

2.2. For electronic form
The information on census results will be automatically calculated and displayed after DTV completes the household interview. DTV is not required to calculate and record information in this section.

3. Confirmation signature
3.1. For a paper form
After completing the interview and checking the information recorded on the form, DTV must read to the information provider some of the most basic information recorded on the form (the first 7 questions). Before leaving the household to move to the next household, DTV asks the information provider (the head or the representative of the household) to write their full name and sign the section reserved for information providers. Finally, DTV writes their full name and signs the section reserved for DTV.

For households that used 2 or more sets of forms, only sign the first set of forms to confirm.

3.2. For electronic form
After completing the interview, the program will automatically display a list of household members, DTV only needs to check the name of the person who provided information to complete the census form.

III. How to question and identify the actual permanent residents in the household
DTV carefully reads the instructions on how to identify NKTTTT in Section VII, Part II to understand the concept and regulations on NKTTTT. DTV asked questions from Q1 to Q8 to identify NKTTTT in the household.

Question Q1: DTV asks and records the full name of each person who regularly eats and resides at the household for 6 months or more by 0:00 April 1, 2019, regardless of whether they have permanent household registration.

[p.39]

Note: These people do not include students who are members of the household but study away from home (no longer eat and reside in the household regularly) or members of the household that have worked away from home for 6 months or more and only return home on weekends, holidays, Tet holiday.

In case there are 2 people in the household with the same last name and middle name, DTV must write additional letters to mark the difference (use letters A, B, etc.).

Question Q2: DTV asked to identify anyone in the household that has moved in less than 6 months by 0:00 April 1, 2019 but intends to eat and reside permanently in the household for a long time or has no other permanent place of residence (including children born before April 1, 2019). If so, DTV checks the corresponding answer box and adds the full name of each person in Question Q1, then asks Question Q3.

This question is intended to identify some special cases that although the individual eating and residing at the household for less than 6 months up to the time of the census, they can still be identified as NKTTTT in the household. Note that these people include those who have moved their whole household to the household being interviewed.

In case the newborn has not yet been given a name, DTV writes "Newborn" and encloses the child's last name in "( )". For example: Newborn (Nguyen).

Question Q3: DTV asks to identify people although eating and residing at the household will not actually be counted as NKTTTT in the household.

DTV reads aloud each case listed in the question. If the household answers "Yes", DTV checks the corresponding box and then asks who is next to cross out his/her name in Question Q1. Cross out a name like the following example: Nguyen Thi Hoa.

For electronic form: Sentence Q3 is split into Q3a and Q3b. Question Q3a lists all the cases for DTV to ask in turn and check the corresponding answer ("Yes" or "No"). Question Q3b only appears if the household has at least 1 of the cases listed in Question Q3a (the answer is "Yes"); then, the list of the members of the household in Question Q1 will automatically appear for DTV to select the corresponding member.

Question Q4a: DTV asks to identify people who still regularly eat and reside at the household but are away temporarily at the time of the census. According to regulations, these people are still identified as NKTTTT in the household.

DTV reads each case aloud. If the household answers "Yes", DTV checks the corresponding box. If the household has at least 01 of the cases listed in Question Q4a (the answer is "Yes"), DTV proceeds to Question Q4b. If no one belongs to the listed subjects, DTV moves on to Question Q5a.

[p.40]

Question Q4b: DTV clearly records the full names of people who are temporarily away corresponding to the case(s) where "Yes" was the response to Question Q4a (if any).

Question Q5a: DTV asks to identify if anyone regularly ate and resided at the household but passed away after 0:00 April 1, 2019 and has not been recorded.

Question Q5b: DTV clearly records the full names of people who regularly ate and resided at the household but passed away after 0:00 April 1, 2019 and have not been recorded (if any).

Question Q6: DTV reads out the names of people not crossed out in Question Q1 and whose names are in Question Q4b and Question Q5b. By convention, these people are identified as NKTTTT in the household.

For electronic form: The form will automatically list the people who are NKTTTT in the household.

Question Q7: DTV asks to identify who is the head of the household among NKTTTT in the household.

The head of the household is the person who is knowledgeable of the information of other members and is acknowledged by other members of the household. The head of the household may or may not be the same as the one recorded in the household registration book issued by the police.

For households whose parents are both managed by the military and police and are censused under a separate plan, only the child(ren) is censused by the locality, the child(ren) is also identified 1 household. The head of the household will be the oldest child.

Question Q8: DTV asks to identify among NKTTTT in the household, how many people have permanent household registration in this commune/ward/town.

According to Article 18, Residence Law No. 03/VBHN-VPQH dated 11/7/2013, permanent household registration means that a citizen registers his/her permanent residence with a competent state agency and is registered permanent residence, issued household registration book by this agency.

[p.41]

Part V: Instructions on how to question and record information on the census form

Part 1: Information about members of the household
Part 1 of the Census form consists of 41 questions, numbered sequentially from Question 1 to Question 41.

The respondent is the head of the household or a person knowledgeable about members of the household. For information on employment and birth history of women, DTV needs to interview DTDT face-to-face and collect information. In addition, for other information about members of the household, if the head of the household or the information provider is not knowledgeable, DTV also needs to interview DTDT face-to-face and record the information.

Question 1: Full names of people who are actual permanent residents of the household, starting with the head of the household

Information about NKTTTT in the household was asked and identified by DTV in the first part of the census form, so DTV does not have to ask this question again.

DTV records the full names (with accents) of people not crossed out in Question Q1 and named in Question Q4b and Question Q5b in the columns corresponding to Q1, starting with the head of the household (whose name appears in Question Q7).

If the household used 02 or more sets of forms, the head of the household is recorded in the first column of the first set. From the second set of forms, DTV leaves the first column blank and writes the names of other members of the household in the next columns.

For electronic form: Names of members of the household will be automatically transferred from Questions Q1, Q4b, and Q5b to corresponding columns, DTV does not have to record the names of members of the household.

Question 2: How is [the respondent] related to the head of the household?
Relationships with the head of the household include:

Question 3: Is [the respondent] male or female?
For those who are interviewed face-to-face or are at home when DTV visits for the interview, DTV can easily identify whether the individual is male or female to check the appropriate code box. However, for young children and people who are away, DTV should not rely on "middle name" to infer whether the individual is male or female, DTV must ask the head of the household.

For people with two sexes, DTV relies on DTDT's answers to record information.

Question 4: [the respondent] was born in which month and year according to the solar calendar?
The month and year of birth are recorded according to the solar calendar and are the actual month and year of birth. DTV does not rely on any kind of document (ID card, household registration book, etc.) to record the month and year of birth unless DTDT confirms that the month and year of birth or that of members of the household is the same as that on the document provided by the household. DTV tries to obtain the month and year of birth to have sufficient information for other contents of the form, especially for children under 5 years old.

[p.43]

Some notes when identifying the month and year of birth according to the solar calendar:

Since the time of the census is April 1, 2019, people born between January and March of the same year will have the same way of rounding their age; People born between April and December in the same year will have the same way of rounding their age. Therefore, in case DTDT still cannot remember their month of birth after the probing questions, DTV tries to find out whether DTDT was born in the first 3 months or the last 9 months of the solar year to randomly choose 1 month in the first 3 months or the last 9 months of the year to write in the corresponding box.

After more probing questions but DTDT still cannot remember their month of birth, DTV writes code "98" (for electronic form, select code "KXD"). Then proceed to ask DTDT the year of birth according to the solar calendar.

[p.44]

In case DTDT does not remember the year of birth, DTV writes code "9998" (for electronic form, select code "KXD" or enters code "9998").

Question 5: How old is [the respondent] now according to the solar calendar?
This question is only asked and recorded for people who cannot remember the year of birth in order to collect information about the rounded solar age of DTDT. Therefore, when DTDT answers about their age, DTV has to ask "Is it the lunar or solar age?" If DTDT answers the lunar age, DTV must subtract 1 to get the solar age and write the information in the box.

When DTDT cannot remember their age, DTV can refer to relevant records and documents or discusses further with other members of the household to record the age or probe to estimate the age. It is possible to probe by comparing the age of DTDT with the age of someone in the household or the age of the people around whose exact age is known.

If the age probing measures do not work, DTV must estimate the age of DTDT by observing DTDT, that is observing the appearance of DTDT combined with the age of DTDT's children, spouse, etc. to estimate the approximate age for DTDT. Please note, this is the last viable option, only implemented when all attempts to probe the age do not work. Do not leave a blank in this question.

Question 6: What ethnicity does [the respondent] belong to?
If DTDT answers other ethnic group, DTV asks and records the name of the ethnicity commonly used in the locality (ethnic branch) and the name of the main ethnicity on the solid lines, and relies on the "List of Vietnamese ethnicities" in Appendix 2 to enter the appropriate code. Record like the following example: DTDT declares that the ethnicity is "Trieu Chau." DTV writes "Trieu Chau (Hoa)" and then records the ethnicity code as "04".

Some cases of ethnicity identification:

Question 7: Does [the respondent] follow any religion? If so: What religion is that?
DTV asks and lets DTDT identify their own religion (regardless of whether DTDT is a follower of that religion).

If the answer is "Yes", DTV asks and records the religion name and code based on the "List of religions" in Appendix 3.

In case the religion provided by DTDT is not on the "List of religions", DTV identifies that DTDT does not follow a religion.

In case DTDT is not sure whether they follow any religion or answers "Luong", DTV identifies that DTDT does not follow a religion.

Test 1 (KT1)
The test question is intended to identify people under 5 years old (born after March 2014) to proceed to Question 8; for people aged 5 years and older (born before April 2014), DTV proceeds to Question 9.

For people with a year of birth but no information on month of birth (month of birth in Question 4 is recorded as code "98"), DTV identifies people born after 2014 to proceed to Question 8; for people born in 2014 or earlier, proceed to Question 9.

Question 8: Is [the respondent] registered for birth now?
This question is intended to collect information on birth registration status for children under 5 years old (born after March 2014).

Birth registration is the registration of birth for a newborn child at a competent state agency and must be carried out within the statutory period from the child's date of birth.

[p.46]

In case a child has been registered for birth by his/her family but is waiting for the birth certificate, it will still be counted as having registered for birth.

Question 9: 5 years ago (April 1, 2014), where did [the respondent] actually reside permanently?
The actual permanent place of residence is understood as the place where DTDT eats and resides regularly (according to the defined concepts of NKTTTT).

For people who 5 years ago, i.e. April 1, 2014, were studying, working abroad, visiting relatives, or traveling abroad within the prescribed time limits, their actual permanent place of residence is still identified as Vietnam, in the household where they are identified as NKTTTT. Thus, in order to have accurate information for this question, DTV needs to ask supplemental questions such as time, the purpose of traveling abroad, etc.

Cases identified as being "abroad" 5 years ago may include: People who 5 years ago obtained citizenship/settled abroad or who 5 years ago studied or worked abroad beyond the prescribed time limits but now actually reside permanently in Vietnam.

Question 10: What province/city/district did [the respondent] move from?
DTV asks and records the name of the province/city and the name of the district on the solid lines; writes province/city code and district code based on the "Administrative Directory of Vietnam" in Appendix 11 and Appendix 12.

If a person is identified as having moved from another district, but the name of that district has now changed compared to that on April 1, 2014 (due to a change in administrative boundaries or change in the name of an administrative unit, etc.), DTV writes its names according to the name of the new administrative unit. In case DTDT does not know the new name of the administrative unit, DTV should ask other members of the household or find other sources of information to identify and record information.

Question 11: 5 years ago, was the aforementioned actual permanent place of residence of [the respondent] ward/town or commune?
The identification of urban and rural areas is based on commune level administrative units: If "ward" and "town", then identify as urban. If "commune", then identify as rural.

[p.47]

Ward/town or commune must be identified as of April 1, 2014. For places that were communes as of April 1, 2014, but now recognized as wards or towns, DTV still has to check the code "Commune."

Question 12: What is the main reason that [the respondent] moved to the current place of residence?
DTV asks and identifies the main reason that DTDT moved to the household. If DTDT gives 2 or more reasons, DTV tries to ask and identify 1 reason that has the most impact on DTDT moving to the household (main reason).

Question 13: Does [the respondent] have any difficulty when [...]?
This question is intended to gather information about difficulties a person may encounter in performing certain activities due to health problems/long term health problems, including difficulties due to the effects of old age, but does not include difficulties due to the children being young or not yet proficient in taking care of themselves (help from adults).

DTV asks about the conditions and level of difficulty of each person and in turn according to each ability, including vision, hearing, walking up the stairs, memory, self-care, and communication. Therein:

[p.48]

Question 14: At the moment, does [the respondent] attend school, has dropped out, or has never attended school?
Attendance status is identified based on whether DTDT is attending/has ever attended any program in the National Education System, including educational levels and equivalent training levels: preschool, elementary school, middle school, high school, intermediate school (vocational/professional), college (vocational/professional), university, master and doctorate.

If the program that DTDT is attending does not belong to one of the above educational levels and training levels, it is not considered "attending school."

DTDT is identified as "dropped out" if he/she has attended a class in one of Vietnam's National Education Systems up to now including the national education system during the French colonial period, the education system from 1945 to 1954, the system of continuation education, the Northern education system, and the current education system.

Some notes:

Question 15: What is the level of education and training [the respondent] is pursuing?
This question is only intended for people attending school (Question 14, select code "1").

[p.49]

Notes:

Question 16: What is the highest level of education and training [the respondent] graduated/achieved?
This question is intended for people who dropped out or are studying at the primary school level or higher. DTV relies on relevant documents (degree of the highest level) or the type of program completed to identify the information for this question.

A person, who has completed a level of education or a State education, training, and vocational program but there has not been a decision to award a diploma or certificate for completing that level of study, is still counted as "attending study" at the level/program of study completed but not yet awarded a degree; the highest degree achieved is the level directly below the "attending school" level.

Example 1: A person has completed the defense of a doctoral thesis but is waiting for approval to obtain the degree, and there has not been a decision to award the doctorate, the highest level that person graduated is a master's degree.

Example 2: Since 2015, elementary school pupils who have completed the grade 5 program and are confirmed in the report card as "Completed Primary School Program" are considered to achieve the primary education level.

Some notes on identifying the highest level of education and training are as follows:

Question 17: What is the highest general education grade that [the respondent] has completed?
This question is only intended for people who are attending school (primary school or higher) or have dropped out. DTV records the highest general education grade (the 12-year system) that DTDT completed, promoted, or graduated.

In case DTDT studied under a general education system other than the 12-year system, DTV uses the "General education levels conversion table" in Appendix 5 to convert to the 12-year system. According to Article 26, Vietnam Education Code 2005 and Decision No. 1981/QD-TTg dated October 18, 2016 of the Prime Minister approving the Structural framework of the national education system, general education includes: primary education, secondary education, and high school education.

Some notes in identifying the highest general education grade:

[p.53]

Question 18: What is the total number of school years completed in all levels of training from basic level upwards of [the respondent] (If any)?
DTV asks and records the total number of years that DTDT completed in all training programs from the basic level upwards (excluding certification programs).

The total number of school years completed is the number of years required to study in order to achieve a certain level of training without counting the number of years repeated or the number of years for which results are reserved. For people who have not studied at any training level from the basic level upwards, DTV records the number of school years as "0".

For example: The training program in Business Administration at Hanoi National Economics University consists of 4 years. For a person that had to study for 6 years to graduate (repeated 2 years), DTV only records the total number of school years as "4".

Some cases to notice:

For example: A person learned electric welding for 9 months, then learned to repair motorcycles for 10 months, then learned to install interior electrical for 11 months. The total time of this person's basic professional training is: 9 months + 10 months + 11 months = 30 months = 2 years + 6 months. In this case, DTV records the total number of school years as 3 years (6 months are rounded to 1 year).

For example: A person learned electric welding for 8 months, then learned to repair motorcycles for 10 months, then learned to install interior electrical for 11 months. Total time of this person's basic professional training = 8 months + 10 months + 11 months = 29 months = 2 years + 5 months. In this case, DTV records the total number of school years as 2 years (5 months are rounded to 0 year).

Identifying examples for Question 17 and Question 18: A person who graduated from Hanoi National Economics University after 4 years of study. Then the person studies for a master's degree for 3 years at Hanoi National Economics University. In addition, after completing the first year of graduate school, the person studied for a College Degree in Informatics from Hanoi University of Science and Technology for a period of 3 years. The person graduated with the College Degree in Informatics 1 year after graduating from the Master of Economics program. DTV identifies as follows: Question 17, record the general education grade as 12 years; Question 18, the total number of school years as: 4 years + 3 years + 1 year = 8 years.

[p.55]

Identifying example for Questions 16 to 18: A person did not complete grade 10 but dropped out. The person then studied at an intermediate transportation school for 2 years, and the person was awarded an intermediate degree which is his/her highest degree. While studying at the intermediate school, the person studied additional knowledge to complete the high school program. DTV records Questions 16, 17, and 18 as follows:

[A figure is omitted here]

Test 2 (KT2)
The test question is intended to identify people with the highest education and training level who graduated/achieved below primary school (Question 16=1) to proceed to Question 19; with other cases (Question 16 not code 1), DTV proceeds to test question 3 (KT3).

Question 19: At the moment, is [the respondent] able to read and write?
Ability to read and write: The ability to read and write a simple passage in daily life in the Vietnamese language, an ethnic language or a foreign language.

If DTDT can read but cannot write, DTV records the person's ability to read and write as "no".

Test 3 (KT3)
The test question is intended to identify people 15 years of age or older (born before April 2004) to inquire about marital status; for people under 15 years old, DTV asks for the general information of the next person.

[p.56]

Question 20: What is [the respondent]'s current marital status?
The question is intended to collect information about DTDT's current marital status (i.e., at the time of census on April 1, 2019). A person's marital status can only fall into one of the following five categories:

Test 4 (KT4)
The test question is intended to identify people aged from 15 to 39 (born from April 1979 to March 2004) to proceed to Question 21; for people aged 40 and over, DTV asks Question 23.

In case the month of birth cannot be identified (the month of birth in Question 4 is recorded as "98"), DTV proceeds to Question 21 for people born between 1980 and 2004.

Question 21: [the respondent] got married for the first time in which solar month and year?
The question is intended to collect information about the solar month and year when people aged 15 to 39 got married for the first time.

The first marriage is the first marriage of DTDT that is recognized by local laws, customs, and practices; or living together with someone of the opposite sex for the first time as a spouse.

[p.57]

The way to ask and write Question 21 is the same as that for Question 4 "The month and year of birth according to the solar calendar" (see instructions on how to ask and record for Question 4). Please note, the question is only intended for people aged 15 - 39, so DTDT tends to remember the month and year of their first marriage.

Question 22: How old was [the respondent] according to the solar calendar when getting married for the first time?
The question is only intended for people who do not remember the year of their first marriage (Question 21, select code "9998").

The question is intended to collect information about the rounded solar age of DTDT at the first marriage. Therefore, when DTDT answers about their age at first marriage, DTV has to ask "Is it according to the lunar calendar or solar calendar?." If DTDT answered that it is according to the lunar calendar, DTV must subtract 01 to get the age according to the solar calendar (because the age according to the lunar calendar is usually 1 year more than the solar calendar).

In case DTDT cannot remember his/her age at the first marriage, DTV can use relevant records, and documents (for example: marriage certificate) or discuss with other members of the household to inquire about the age of DTDT at the first marriage.

Question 23: In the past 7 days, did [the respondent] do any work for 1 hour or more to generate income for themselves or their family?
DTV asks about the past 7 days before the day DTV visits the household to interview. For example: If DTV visits the household on April 10, 2019, the past 7 days is from April 3 to April 9, 2019. If DTDT passed away after the time of the census (after April 1, 2019), DTV asks for information about DTDT's work in the 7 days before their death.

Work is an activity in 1 hour or more that generates income and is not prohibited by law. Therefore, if DTDT does work prohibited by law in the past 7 days before DTV visits the household, DTV identifies that DTDT does not work (Question 23=2).

(1) Some of the work identified as working to generate income for themselves or their family includes:

(2) Some cases are not counted as working to generate income for themselves or their family include:

[p.59]

Question 24: Although not working, does [the respondent] get paid/remunerated or get benefits from production and business activities?
The question is intended to identify whether, during the idle periods, DTDT continues to get paid/remunerated or get benefits from his business and production activities. If during the idle period, DTDT still receives salary/wages/benefits from the production and business activities, it proves that DTDT's level of commitment to the work is quite high and DTDT will be identified as employed. In case DTDT does not receive salary/wages/benefits during the idle period, DTV must ask follow-up questions to identify DTDT's economic status. DTV relies on DTDT's answers to select the appropriate code.

Some cases to notice:

Question 25: Does [the respondent] already have a job and will return to it in the next 30 days?
The question is intended to identify more information about people, although not working in the past 7 days to generate income, not getting paid, but having a level of commitment to a certain job to identify the employment status of DTDT.

For example: A person is a carpenter, in the past 7 days he took his child to Hanoi to study for the university exam, so he did not do carpentry, nor did he do anything to generate income. He intends to return to carpentry in 1 week (from the time DTV conducts the interview). Thus, DTV identifies the answer as code "1".

For women on maternity leave, DTV asks to identify if at the end of the maternity leave as prescribed by the State (6 months), they will definitely return to the job that they took leave from within the next 30 days.

[p.60]

Question 26: Please describe the main job and title (if any) that [the respondent] did in the last 7 days or before taking temporary leave
DTV asks about the main job that DTDT did in the last 07 days; priority is given to asking about regular jobs that DTDT did even though they might not do this regular job in the last 7 days (if in the last 7 days they did not do this regular job, the question will be the same as that for people on temporary leave); if there is no regular main job, ask about the temporary job they did in the past 7 days.

Main job: Refers to regular, stable, or relatively stable work, the work that takes up the most time of DTDT.

For people who do not have a regular job but only have a temporary job (temporary, irregular, unstable), their main job in the past 7 days is the temporary job that took up the most time or generated the most income in the 7 reference days.

After identifying the main job, DTV asks to record a detailed description of this job (the more detailed the better); record the job title assigned to DTDT (if any) to perform the duties. The specific and detailed description of the job and title will help the recording of the job code more conveniently and accurately.

DTV leaves blank 4 boxes "job code" in the census form. Some notes when identifying the main job:

Examples of how to record descriptions of the main job and title are as follows:

[A table is omitted here]

[p.62]

Question 27: What is the name of the facility (if any) and the main product or service of the facility where [the respondent] worked in the past 7 days or before taking temporary leave?
DTV needs to specify the name of the business facility (if any) and the main products/services that the DTDT's facility produces or performs.

The concept of "facility" mentioned in the question is a basic economic unit, understood as the smallest economic entity, which can be an enterprise, company, corporation, socio-economic organization, agency with legal status, a household, etc., regardless of economic type, as long as the value of products/services generated from the facility can be accounted/determined independently of other facilities.

DTV left blank 4 boxes "industry code" in the census form. For example: DTDT works at the Cement Packaging Production Factory of Nghi Son Cement Corporation and the products of this enterprise can be accounted for separately (costs calculated separately). For this question, DTV records as follows:

[Figures are omitted here]

[p.63]

Test 5 (KT5)
The test question is intended to identify people who have jobs and have not achieved any level of training from the basic level upwards to proceed to Question 28; for the rest, DTV skips to Question 30.

Question 28: Does [the respondent] have a professional certificate or is recognized as an artisan?
Professional certificate: Include people who are granted a national professional skill certificate or have attended vocational training courses for less than 3 months and were granted a professional certificate.

Professional certificates do not include:

Question 29: With the above main job, does [the respondent][...]

a. Work for 3 years or more?

b. Use machines or equipment or have skills in the field of handicrafts?

Question 29b is intended to identify whether in the working process, DTDT controls and uses machines and equipment (mechanization, automation) in most stages of the job or has skills in the field of handicrafts.

Question 30: With the above job, what is the role of [the respondent]?
This question is intended to identify the employment positions of DTDT. DTV reads 5 suggested answer codes and based on the answer of DTDT records information.

Employment positions include the following groups:

[p.66]

Some examples of identifying employment positions:

Question 31: In the past 30 days, has [the respondent] actively searched for a job or prepared to start production or business activities?
This question is intended to identify if unemployed people are actively looking for a job or taking specific actions to prepare to start production and business activities.

Actively looking for a job is when DTDT actively researches and contacts through friends and relatives, through the mass media, through job placement and promotion centers, etc...to find work to generate income.

Preparing to start production and business activities is when DTDT has specific actions and plans to build and set up production and business facilities/activities under their own ownership or co-ownership. Preparing to start production and business activities includes registration of operations and arrangement of necessary resources (capital, human resources, construction/purchase/rent of headquarters/operational location, lease/purchase of labor tools, labor recruitment, etc.).

Question 32: What are the reasons [the respondent] is not looking for a job?
DTV asks to identify DTDT's reasons for not looking for a job. Some reasons such as:

Question 33: In the next 2 weeks, if there is a job or a business activity, is [the respondent] ready to work immediately?
Ready to work is a status in which DTDT is capable and able to arrange to work immediately when required. People who really want to work but cannot for various reasons (ill health, unable to arrange housework, etc.) are considered not ready to work.

Test 6 (KT6)
The test question is intended to identify female members of the household from 10 to 49 years old (female, born from April 1969 to March 2009) to ask Question 34; for the remaining cases, DTV asks the next person.

[p.68]

In case the month of birth cannot be identified (the month of birth in Question 4 is recorded as "98"), DTV proceeds to Question 34 for women born between 1970 and 2009.

Question 34: Have you ever given birth?
Women who have given birth are those who have given birth to a live child (i.e., at birth, the child had at least one of the following vital signs, such as: crying, breathing, heart still beating, throbbing placenta, etc.), excluding cases of stillbirth (i.e. death in the womb). DTV needs to interview DTDT slowly and carefully, especially women of school age and unmarried.

In the case of surrogacy (according to Article 94, Marriage and Family Code of 2014), the child born is the shared child of the husband and wife through surrogacy; surrogate mothers are not treated as if giving birth to their own children; Women who ask for surrogacy are treated as if giving birth to their own children.

Question 35: Number of sons and daughters born to you currently living in your household?
DTV records the number of sons and daughters born to DTDT currently living in the same household as DTDT (recorded in the list of members of the household in Question 1) in the corresponding boxes. If there is no son or daughter born to DTDT currently living in the same household, DTV records "00" in two corresponding boxes (for electronic form, record "0").
For children who are currently abroad in the prescribed time limits (before going abroad, the children live in the same household with the mother), DTV still counts them as children living in the same household with the mother. (these children are counted as NKTTTT in the mother's household and are named in the list of household members in Question 1).

Question 36: How many sons and daughters born to you are living elsewhere?
DTV records the number of sons and daughters born to DTDT not currently living in the same household with DTDT (living elsewhere or living in the same house/apartment with DTDT but eating separately). If there is no son or daughter born to DTDT not currently living in the same household as DTDT, DTV records "00" in 2 corresponding boxes (for electronic form, record "0").

In case the woman's children are under the management of the military or police and are living in the same household, by convention the children are counted as living elsewhere, DTV records information in Question 36.

[p.68]

Question 37: Did you have any children born alive but then deceased? IF SO: give the number of deceased sons and daughters.
DTV asks about the children born alive to DTDT but passed away before the time of the census. This is a sensitive question, DTV needs to interview slowly and carefully, especially in cases where the DTDT's children were born alive but passed away at an early age.

DTV records DTDT's answer in the blank box. If there is no son or daughter born alive to DTDT but deceased before the time of the census, DTV records "00" in two corresponding boxes (for electronic form, record "0").

DTV must not leave a blank in any of the large boxes in the response sections of Questions 35, 36, and 37.

Question 38: Month and year of most recent birth according to the solar calendar?
The most recent birth is the "live birth" of DTDT closest to the time of the census, regardless of whether the child is alive or deceased, living in the same household with DTDT or in a different household. The way to ask and write Question 38 is the same as that for Question 4 "The month and year of birth according to the solar calendar" (see instructions on how to ask and record for Question 4).

Question 39: The number of sons and daughters of the most recent birth?
DTV asks for the number of sons and daughters of the birth in Question 38 (most recent birth). Usually, this question only contains information about the number of sons or daughters. However, in the case of twins, triplets, etc. of the opposite sex, there is information about both the number of boys and the number of girls in this question.

In case of no events, DTV records "00" in 2 corresponding boxes (for electronic form, record "0"). Do not leave any boxes blank.

Test 7 (KT7)
The test question is intended to identify women who have had the most recent birth within the last 12 months (April 2018 to March 2019) to proceed to Question 40; otherwise, DTV skips to test question 8 (KT8).

Question 40: Number of sons and daughters born to you from April 2018 to March 2019?
DTV asks to identify the number of sons and daughters born to DTDT within the past 12 months.

[p.69]

Question 40 is intended to identify, in addition to the most recent birth within the last 12 months (Question 39), whether DTDT gave birth to another child in the same year. Therefore, the information about the number of sons and daughters in Question 40 must be equal to or greater than the number of sons and daughters in Question 39.

Test 8 (KT8)
The test question is to identify women who have had the most recent birth within the past 2 years (from April 2017 to March 2019) to proceed to Question 41; otherwise, DTV asks the next woman.

Question 41: Who was your midwife during your most recent birth?
DTV asks to identify the midwife for DTDT in her most recent birth.

The midwife for DTDT in her most recent birth might be medical staff, village health workers/village midwives, other people (relatives, friends, etc.), or "none".

Some notes when identifying the midwife:

Test 9 (KT9)
DTV checks if there are unmentioned members of the household, and if so, then continue the interview; if there is none, proceed to Part 2.

[p.70]

Part 2: Information about the deceased of the household
DTV collects information about people who were members of the household but had died during the period from February 16, 2018 (the 1st day of the Year of the Dog, 2018) to the end of January 31, 2019 according to the solar calendar. In case the whole household is deceased (after the time of making the list until the end of March 31, 2019), DTV must inquire indirectly through key local officials, relatives of the deceased or through civil status documents, household registration in the locality, tic. and records on the census form.

Information on the deceased is often difficult to collect, especially information on infant and neonatal deaths (especially deaths within 1 week of birth). Therefore, in order to collect this information thoroughly and accurately, DTV needs to skillfully ask probing questions to get accurate answers.

For paper form: For households that used more than 1 set of forms, information about the deceased of the household is recorded in the last set of forms.

For electronic form: The questions on the deceased of the household are designed so that DTV can enter information about each deceased person in turn.

Question 42: From February 16, 2018 (the 1st day of the Year of the Dog, 2018) to the end of March 31, 2019, did any of the actual permanent residents of your household pass away (including young children)?
DTV asks to identify if the household had anyone pass away in the period from February 16, 2018 (the 1st day of the Year of the Dog, 2018) to the end of March 31, 2019 according to the solar calendar.

Question 43: Could you please tell me the full name of (each) deceased person?
DTV writes the full name of (each) deceased person of the household on the solid line(s) of the column(s) in Question 43. If the household has more than 1 deceased person in the reference period, the name of each person is in 1 column; at the same time, DTV numbers (each) deceased person in the corresponding boxes according to the natural number starting with 1 in the first column.

For electronic form: DTV does not have to fill in the "ordinal number" information, the electronic form will automatically record this information. After DTV enters the full name of 01 deceased person, the census form will skip to the next questions in part 2 to ask for corresponding information about that person. If the household has more than 1 deceased person, the electronic form will repeat the questions in part 2 in a similar way to the first deceased person of the household for DTV to collect information.

[p.71]

Question 44: Is [the respondent] male or female?
DTV asks to identify the sex of the deceased. Please note, DTV must not rely on "middle name" to guess whether the deceased is male or female, DTV must ask the head of the household.

Question 45: In which month and year of the solar calendar did [the respondent] pass away?
DTV asks about the month of the solar calendar that the person passed away. If the household only remembers the month of the lunar calendar the person passed away, DTV needs to convert it to the solar month. If the respondent cannot remember the month the person passed away even though DTV has tried to apply methods to extract information such as asking about the month/season of the lunar calendar, reviewing the death certificate, etc. DTV record code "98" (for electronic form, select code "KXD"). However, because the reference period for calculating the time of death in the household is more than 13 months prior to the time of the census, most of the households remember information about the month of death. Therefore, DTV should try to extract this information.

DTV asks the head of the household about the year of the solar calendar the person passed away to select the year "2018" or "2019".

Question 46: [the respondent] was born in which month and year according to the solar calendar?
DTV should ask about the month of the solar calendar the person passed away. The way to ask and record for Question 46 is the same as that for Question 4 "The month and year of birth according to the solar calendar" (see instructions on how to ask and record for Question 4).

DTV should pay special attention to obtaining information about the month and year of birth according to the solar calendar in the cases of child deaths because in these cases, especially with children under 5 years old, the recall time is not too long, moreover, this is very important information in calculating the population and demographic indicators of TDT 2019.

Question 47: At the time of death, how old was [the respondent] according to the solar calendar?
DTV asks Question 47 when there is no information about the year of birth in Question 46. DTV extracts information to identify the rounded solar age of the deceased up to the time of their death. DTV must not leave a blank for the information in Question 47.

[p.72]

Question 48: What are [the respondent]'s causes of death?
DTV asks to identify the direct causes of death for the deceased of the household. Causes of death are divided into the following groups:

Test 10 (KT10)
The test question is intended to identify women aged 10 - 54 who passed away due to illness or other causes to proceed to Question 49; otherwise, skip to Test 11 (KT11).

[p.73]

Question 49: What are the circumstances of [the respondent]'s death?
DTV asked about the causes of death in women aged 10 - 54 to find out more information about deaths related to pregnancy and childbirth.

Test 11 (KT11)
DTV checks whether anyone else in the household had passed away during the period from February 16, 2018 (the 1st day of the Year of the Dog, 2018) to the end of March 31, 2019 according to the solar calendar. If there is none, proceed to Part 3.

Part 3: Information about housing
The DTV collects information about the housing situation of the household. Do not collect housing information for specific demographics.

Question 50: Does your household have a house?
The DTV observes to determine whether the household has a house (regardless of whether the household has ownership of the house or not). In the event that the DTV either cannot observe or clearly determine, they should ask the DTDT to determine the information for Question 50.

[p.74]

A household is defined as having a house if the household lives in a building consisting of 3 elements: walls, roof, and floor. In case a household's residence is a boat house on a river or a lake which has all 3 elements: walls, roof, and floor; then that household is considered as having a house.

In case the household is living in a temporary shack because the household's house is being constructed, the DTV determines the household's housing status as "No, under construction and living in a temporary shack".

Question 51: Is your household living with other household(s) in the same house/apartment?
A household is considered to be sharing a house with another household when the house/apartment in which they live does not meet the standards of being structurally separate and independent, having shared area such as a living room, bathroom, entrance, ...

Question 52: Is your household a representative household?
This question aims to identify 1 household among the households living in the house/apartment who will answer the detailed housing information in the following questions.

Question 53: Is the house/apartment that your household is living in a condominium or a discrete house? How many separate bedrooms does this house/apartment have?

[p.75]

Question 54: How many square meters is the total livable space of the house/apartment?
The DTV asks to determine the total actual livable space of the house/apartment, not based on the total floor space on papers and records.

Note: As for loft, the area is calculated when it is 2.1 m or higher, has a minimum area of 4 m2, and is used for living.

Some notes in determining the total usable area of the house/apartment:

For example: A 4-story house, the floor area of each floor is 40 m2 and is built from the 1st to the 4th floor; only on the 4th floor, only one room of 15 m2 is built as a worship room, and the rest is surrounded by sturdy wire mesh and used for washing and drying clothes. The total livable area of the house is:40 x 3 + 15 = 135 m2.

Question 55: What is the main material for columns (or pillars, or load-bearing walls) of this house/apartment?
A column (or pillar, or load-bearing wall) is a structural element built to support a roof (or ceiling, or beam).

[p.77]

The determination of the quality of timber used to make columns (or pillars, or load-bearing walls) is based on Vietnam's current classification of timber groups, in which durable timbers are those belonging to groups I, II, III, IV, V; low quality, fragile timber are those belonging to groups VI, VII and VIII or young trees, with a diameter of less than 10 cm. Details of timber species are presented in the "Nationwide unified provisional classification of timber types table" in Appendix 13.

Some column materials are specified as durable materials, including: reinforced concrete, brick/stone, and durable iron/steel/wood.

Some materials for making columns are specified as temporary materials, including: low-quality wood/bamboo, earth, ...

In case the household regularly lives in 2 or more houses on the same lot, the main material for making columns is taken from the main house.

Question 56: What is the main material for the roof of this house/apartment?
The DTV asks questions in combination with observations to determine the correct information for Question 56.

The roof is the part located on the top of the house, to protect the building from top to bottom (provide cover from rain and sun, heat insulation, heat preservation, waterproofing - covering function) and connected to walls, columns, beams, and bracing elements of a residential building, creating the overall stability of the whole building (bearing function).

Some roofing materials are specified as durable materials, including: reinforced concrete, and tile.

Some roofing materials are specified as temporary materials, including: roofing sheets (fibre cement, thin plastic, sheet metal), leaves/straw/oil paper, or other materials.

In case the roof is made of tiles imitating tole, cold tole, insulated tole, corrugated tole and has a firm supporting structure (iron frame, timber, etc.) which is firmly connected to the masonry wall, reinforced concrete column, then the tole roof is considered to be made of durable material.
In case the house has 02 or more roof layers (heat-proof, leak-proof roof layers,...), DTV asks to determine the main material of the roof built to protect the building; excluding heat-resistant, leak-proof layers as the main materials of the roof.

In the case of a solidly built house with one floor or more, the roof of the first floor (ground floor) is made of concrete, on the top floor pillar concrete columns are made, surrounding walls are built, and the roof is covered with tole, fibre-cement, plastic panels, and plaster ceilings,...and this top floor is used for living activities, then the DTV determines that the main material for the roof of this house is concrete roof.

[p.78]

In case the household regularly living in 2 or more houses on the same lot, the main roofing material is taken from the main house.

Question 57: What is the main material that makes up the wall or shelter of this house/apartment?
The DTV asks questions in combination with observations to determine the correct information for Question 57.

The wall is one of the main structural elements that take on the function of covering, dividing up the spaces, and bearing the load on the ground of the house. This is also the element that helps to distinguish the space inside and outside the house, between one room and another. The wall also has a load-bearing function, supporting the weight, of the roof and conducting it to the foundation.

Wall materials are considered durable if they are made of reinforced concrete, brick/stone, timber, and metal.

Wall materials are considered temporary if they are made of lime soil/straw, bamboo screen/plywood, or other materials.

In case the household regularly lives in 2 or more houses on the same lot, the main wall or shelter material is taken from the main house.

[p.79]

[A figure is omitted here]

Question 58: From what year was this house/apartment used?
The DTV records the year in which the house was completed and put into use for the first time. In case a household's house consists of many parts, each part is completed and started to live in different years, the DTV only records the year in which the main part (with the largest area) of that house was completed and first put into use for living.

In case the owner household does not remember which year the house was put into use, the DTV chooses the code "Undetermined".

With remodeled houses: If a major repair causes changes to the structure of the house, record the year of the repair; If minor repairs, enter the year of the most recent major repair or the year of first use (in case there was never a major repair).

For example: A house was built in 1990 and has a tiled roof. In 2000, the tiled roof was removed, and renovated to facilitate pouring a concrete ceiling and building an additional floor. In 2005, the house was renovated and another floor was built. In this case, the DTV records the year of use of the house as 2000 because this is the year in which the house underwent its biggest structural change.

Question 59: Who owns the house/apartment that your household is living in?

For example: A tenement room was allotted to Mr. A's family to use. After a period of usage, Mr. A's family leased it to Mr. B's family. In this case, the DTV identifies Question 59 for Mr. B's family as "House rented from individuals/private entity".

Question 60: In the near future, does your household plan to buy a house/an apartment? If so: Where (province/city) does your household plan to buy a house/an apartment?
The DTV asks to determine if the household plans to buy a house. If yes, DTV asks where (city/province) the household plans to buy a house and selects the appropriate code from Appendix 11.

In case the household is uncertain about the plan to buy a house or the decision is not unanimous, the DTV determines that there is no plan to buy a house.

In case the household plans to buy, has the money but does not know where (province/city) to buy, or intends to buy a house abroad, the DTV determines that there is no plan to buy a house.

Question 61: What is the main type of fuel (energy) that your household uses for lighting?
The main type of fuel (energy) that households use for lighting is the fuel (energy) that households use the most for lighting in the past year (12 months before the time of the survey).

For example: A household uses electricity from the grid for lighting. In the past 20 days, households had to use kerosene lamps for lighting because the local power station was broken, and has yet to be repaired. In this case, the DTV determines that the fuel used for lighting in the household is the "Electrical grid".

Question 62: What is the main type of fuel (energy) that your household uses for cooking?
Cooking includes cooking rice, cooking food, and drinking water. The main type of fuel (energy) used by the household for cooking is the fuel (energy) that in the past year (12 months before the time of the survey), the household used the most for cooking.

Fuel (energy) used for cooking includes the following types: electricity, gas/biogas, coal, firewood, and other fuels (energy).

In fact, there are households that do not use any fuel (energy) to cook for a long time; they often eat in restaurants and various types of canteen/mess halls. In this case, the DTV chooses the code "Do not use anything".

For example: A household uses an electric rice cooker to cook rice and a gas stove to cook food. In this case, the DTV determines that the main fuel (energy) that the household uses for cooking is gas.

Question 63: What is the main source of drinking water in your household?
The main source of drinking water is the water source that in the past year (12 months prior to the time of the survey) the household has used the most for drinking, regardless of where that water source comes from. Sources of drinking water include the following types:

For example: A household uses tap water for cooking, drilled well water for bathing, and other daily activities. In this case, DTV identifies the main source of drinking water of the household as "Tap water".

Question 64: What type of latrine does your household use?
This questionnaire collects information about the type of latrine that the households use the most in the past year (12 months prior to the time of the survey), regardless of where the latrine is located and who it belongs to. Types of latrines include:

For example: A household rents a room in a motel and uses the shared bathroom and septic toilet every day. In this case, the DTV recorded that the household used "outdoor septic/semi-septic latrines."

Question 65: Currently, does your household have the following types of living equipment?
The DTV reads out the names of the devices so that the household can listen and record the answers.

This question is intended to collect information about the usage of household appliances, regardless of whether these household appliances are owned by the household or not.

Household phone number
After completing Question 65, DTV asks for the mobile phone number of the head of the household (or the adult knowledgeable about household members) or the landline number of the household (including area code) to contact in the event that is necessary to go over some information on the questionnaire again.

Check all information on the questionnaire
The DTV re-checks the information in the questionnaire, including the information of each household member to ensure that the answers have been recorded accurately and completely.

- For paper form:

- For electronic forms: Check the missing information due to the absence of household members (if any) and make an appointment to return or schedule a time to call the phone number directly to supplement information.

After finishing checking the household survey, the DTV thanks the head of the household and household members for their cooperation and help in completing the task and moves on to the next survey household.
