Questionnaire instructions view entire document: text image

4. Month and year of birth
All persons responding question 1 should answer this question.

Interviewers should ask and fill out the actual month and year of birth for every person based on the solar calendar. Persons who have an incorrect date of birth in their legal documents (e.g. personal identification certificate, household registration, birth certification, etc.) can report their correct date of birth in the enumeration form.

If a person does not remember her/his date of birth in the solar calendar, but s/he remembers her/his age and date of birth in the lunar calendar, interviewers can check the calendar conversion table (in the appendix) in order to get the correct year of birth in the solar calendar.

In case that a person does not remember the month of birth but s/he knows her/his age by the lunar calendar, his/her estimated year of birth is, as follow:

Year of birth (solar calendar) = year of census (1989) - age (by lunar calendar) +1

If a person does not remember the date of birth or his/her own age or that for other household members, interviewers can ask several questions to find out estimated dates of birth.

If a person cannot remember his/her age or year of birth, interviewers can look at their appearance and ask them to estimate their own ages and use the calendar conversion table to fill in the year of birth by the solar calendar.

For children, if the interviewee does not remember his date of birth, interviewers can ask months of age and calculate the month and year of birth of the child.

Questionnaire instructions view entire document: text image

Question 4: In what solar calendar month and year was (name) born?

Interviewers need to ask respondent and fill in his/her actual month and year of birth by solar calendar. Interviewers fill in month of birth in two cells in the line for "month". If the month of birth is less than 10, interviewers place "0" in the cell on the left. Filling in the last 3 digits of year of birth in the 3 cells for the line "year".

Note: For persons who were born before April 1899 (100 years old and older), interviewers should also report their information on "List of elderly aged 100 years and older" (appendix 5) after filling in their month and year of birth.

In fact, it is difficult to have correct information on month and year of birth in solar calendar for many people, especially for elderly. Therefore, interviewers should pay attention to several points:

a) Respondent only remembers his/her month, year of birth or age by lunar calendar:

When respondent answer month of birth, interviewers should reconfirm if it is by solar calendar or lunar calendar. If respondent use lunar calendar, interviewers should add 1 unit to have correct solar calendar month of birth (usually, lunar calendar is one month behind solar calendar).

If respondent only remembers year of birth by lunar calendar, interviewers should use "Lunar calendar and solar calendar conversion table" (appendix 2) to convert lunar calendar year into solar calendar year.

In cases where respondent only remembers "zodiac" (chi) (such as: rat, buffalo, tiger, cat, etc.) of his/her year of birth by lunar calendar and can't remember stem/branch (can) (such as: Giap, At, Binh, Dinh, etc.) of that lunar calendar year, interviewers need to ask respondent's age and use "Lunar calendar and solar calendar conversion table" to define year of birth in solar calendar for that person.

In a case, respondent only remember his/her age using lunar calendar, interviewers estimate his/her year of birth in solar calendar, as follow:

Year of enumeration (1999) - age in lunar calendar + 1 = Year of birth in solar calendar

b) Respondent doesn't remember month, year of birth by either lunar calendar or solar calendar

Respondent doesn't remember month of birth: Interviewers need to ask several questions in order to approximate month of birth in solar calendar. If respondent is still not able to report month of birth, interviewers fill in code (**) (not available) in the cells for month of birth.

Respondent doesn't remember year of birth and age: Interviewers can ask several questions to define respondent's age. If respondent is still not able to report his/her age, interviewers may estimate respondent's age (based on his/her appearance, age of the first child, age of brother/sister, etc.), then year of birth in solar calendar. Interviewers shouldn't fill in code "not available" or leave year of birth blank.

Question 9: Where did [the respondent] usually reside five years ago (on 1 April, 2004)?

The concrete way of recording way is as follows: The respondent's place of usual residence 5 years earlier than the census date (on 1 April, 2004) can only be one of the following:

(i) Same commune/ward: If the respondent's place of usual residence 5 years earlier than the census date (on 1 April, 2004) is in the same commune (being recorded in the line "commune/ward" on questionnaire's cover page), then the enumerator marks (x) in the small box next to code "1", and moves to ask Question 11, not to ask Question 10.

(ii) Another commune/ward in the same district: If the respondent's place of usual residence 5 years earlier than the census date (on 1 April, 2004) is in a commune/ward different from the commune/ward of his/her current place of usual residence, but in the same district/quarter that he/she is usually residing, then enumerator marks (x) in the small box next to code "2", and moves to ask Question 10.

(iii) Another district/quarter in the same province/city: If the respondent's district/quarter of usual residence 5 years earlier than the census date (on 1 April, 2004) is another one, but in the same province/city, then the enumerator marks (x) in the small box next to code "3", and at the same time writes down the name of that district/quarter on the printed line, checks its code number in the "List of administrative units of district level" to fill in the 3 boxes, then asks Question 10.

[Graphic example omitted]

(iv) Another province: If the respondents province/city of usual residence 5 years earlier than the census date (on 1 April, 2004) is different from the one that he/she is usually residing, then the enumerator marks (x) in the small box next to code "4", and at the same time writes down the name of the province/city on the printed line. Check the code number of the province/city in Appendix 9 the "List of administrative units of provincial level" and fill it in the 2 boxes and moves to ask Question 10.

[pg.36]

[Graphic example omitted]

(v) Abroad: If the respondent's place of usual residence 5 years earlier than the census date (on 1 April, 2004) is abroad, then the enumerator marks (x) in the small box next to code "5", and moves to ask Question 11, not to ask Question 10.

Note: If a person whose place of usual residence on 1 April, 2004 differs from his/her place of usual residence at the census date, but the name of the place of usual residence on 1 April, 2004 was changed because of adjustment or renaming of administration units, etc., the enumerator must record the name of the previous usual residence according to the current (new) name, not recording according to the previous (old) name.

In case the respondent does not know what the current name of the place of the previous residence is, the enumerator must ask neighbouring people to identify its current name to record.
For a person with no place of usual residence on 1 April, 2004, the enumerator records the name of the place where he/she was present on 1 April, 2004.

Question 8
This is a filter question. The enumerator must check Question 4 or 5. If the respondent is 5 years old or more (Question 4 recorded a date ranging from March 2004 or before, or Question 5 recorded "05" or more), then ask Question 9. In contrast, if the respondent is less than 5 years old (Question 4 recorded a date ranging from April 2004 to March 2009, or Question 5 recorded a code number ranging from "00" to "04"), then end the interview of this person. After that the enumerator moves to ask and record the questionnaire for the next household member. If there is no member in that household, then the enumerator moves to ask and record Part 2: Mortality information.

Question 9: Where did [the respondent] usually reside five years ago (on 1 April, 2004)?

Age: _ _

Questionnaire instructions view entire document: text image

Question 1 to Question 7: Ask about all household's usual residents

Question 4: In what solar calendar month and year was [the respondent] born?
Month and year of birth are recorded in the solar calendar; they are the actual month and year of birth in the solar calendar and are not following any kind of document (identification card, population registration book, etc.).

If the respondent knows the month and year of birth in the solar calendar, then the enumerator records that month and year on the printed boxes. If he/she only remembers the month and year of birth in the lunar calendar, then the enumerator must use the "Conversion between lunar and solar calendar years" (Appendix 7) to convert the lunar calendar month and year to the solar calendar month and year.

Note: The solar calendar year often comes more than 1 month before the lunar calendar year; when converting month of birth in the lunar calendar to the solar calendar, the enumerator should add 1 to the month of birth in the lunar calendar. Thus, persons born from month 1 (thang gieng) to month 11 (thang mot) in the lunar calendar month will become the months of February to December of the same year. If they were born in month 12 (thang chap) in the lunar calendar, their month of birth in the solar calendar will be January of the next year.

If the respondent does not remember the month of birth, the enumerator must use a prompt: In what season was [the respondent] born? Born before or after the lunar calendar Tet, mid-lunar calendar month 7, mid-month 8, born before or after the date of the victory of Dien Bien Phu battle (7 May in the solar calendar), liberation of the South (30 April in the solar calendar), National Day 2 September, Uncle Ho's birthday (19 May in solar calendar), etc. to help the respondent remember the month of birth.

As the Census day is 1 April, those who have the same year of birth and month of birth from January to March will have the same way of calculating completed age, and those who have the same year of birth and month of birth from April to December will have the same way of calculating completed age. Therefore, in case the prompt was used but not successful, try to ask whether the respondent was born in the first three months or in the last nine months of the solar calendar year to select randomly one of the first three months, or of the last nine months to put into the corresponding two boxes.

[pg.33]

If after taking such an effort, the respondent is still unable to remember the month of birth, enumerator will put "98" into the corresponding two boxes and continue to ask about the year of birth.

If the respondent remembers the birth year in the lunar calendar, the enumerator will record that year into four printed boxes. For example, if the birth year is 1954, record "1954" into four boxes, 1 digit per 1 box.

If the respondent does not remember the birth year in the solar calendar, but remembers the birth year in the lunar calendar (for example Binh Ty, At Suu, etc., or even only remembering the animal age: Tiger, Cat, etc.), use the "Conversion between lunar calendar and solar calendar years" (Appendix 7) to choose a corresponding solar calendar year to fill in the corresponding four boxes, then move to ask Question 6, not Question 5.

Note, in using the "Conversion between lunar calendar and solar calendar years" to choose a solar calendar year for the respondent, there would be a difference of 12 years (if the respondent can only remember the age in the animal year: "chi") or 60 years (if the respondent can remember both "can" and "chi"), so it is necessary to ask an additional question "By this year, how old was [the respondent]?" in combination with looking at the face of the respondent to determine the true age to avoid confusion.

In case the respondent is unable to remember the year of birth, the enumerator marks (x) in the small box next to the code number "9999", then asks about Question 5 and leaves the boxes used to record the year of birth in the solar calendar blank.

Question 5: What was [the respondent]'s age at his/her last birthday?
This question is only asked and recorded for those who did not remember their birth year. (In Question 5 marked (x) in the small box next to the code number "9999").

This aims to collect information on the respondent's age in the solar calendar. Thus, when the respondent gives his/her age, the enumerator must ask an additional question "Is that your age in the lunar or solar calendar?" If the answer is "in the lunar calendar", then before filling the age in the two printed boxes, the enumerator must subtract 1 from that age to get age in the solar calendar (because age in the lunar calendar is generally 1 year older than that in the solar calendar).

If the respondent's age in the solar calendar is greater than 95 years old, then the enumerator records "95" in the two printed boxes.

For those whose age in the calendar year is less than 1, the enumerator must fill "0" in the left box.

When the respondent is unable to remember his/her age, the enumerator can refer to related documents or discuss with other household members to obtain the age, or take prompts to make an estimate of age. The prompt can be done by comparing the age of the respondent with the age of any household member or the age of someone nearby knowing the exact age of that person.

[pg.34]

If the prompt is not successful, the enumerator must estimate the respondent's age by looking at his/her body: that is, to look at the outward body in combination with considering his/her children's age, his/her wife/husband's age, etc., to guess an approximation age for the respondent. It is noted that this is an unwilling way, and is only used when no prompt is successful. It is not allowed to put the code of "not stated" for the question of "age in calendar year".

Note: When interviewing and recording Questions 4 and 5, the enumerator must pay attention to find old persons age 100 or older (when Question 4 was recorded as March 1903 or before, or when asking Question 5, the respondent answered an age of 100 or more). If true, the enumerator must fill out the "Notification of persons with age of 100 years old or more" (use Appendix 6 to fill) to submit it to his/her supervisor.

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 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.

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 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.
