1.1 Meaning of Population and Housing Census
The Population and Housing Census is the collection and record of statistical data related to every person living in the same living unit called household. In addition, it includes data of the dwelling of that particular household obtained by the enumeration of every household within each area of the census boundary. Such census recorded data is obtained on the given date of the census. For this particular census the date was April 1, 2000.
The collection and recording of population in Thailand was first conducted in 1909. Subsequent censuses were conducted in 1919, 1929, 1937, and 1947. During these five census years, the Ministry of Interior was solely responsible for registration of population in each of the administrative zones for the benefit of planning and executing the election. This process of the census is now called "Registration with Individuals' Details"
The National Statistical Office has been responsible for conducting the Population and Housing Census since 1960 according to Statistical Act of 1952. The census is conducted every 10 years as stated by the Statistical Act of 1965. The authority and right as stated in that particular act is in line with the recommendation of the United Nation, which suggested that all countries should collect and record information on demographic characteristics and their residential data in every 10 Christian years ending in 0, starting from 1970. This recommendation was put forth to enable the comparison of data from different countries accordingly. The National Statistical Office had conducted household enumeration at the same time as the census of the population in order to obtain the base information of the structural characteristics of the population and household. The 2000 Population and Housing census is the tenth population and the fourth household census enumeration in Thailand. At present, although the Registration with Individuals' Details is available, some individuals within the population have not resided as stated in the Registration. This presents difficulties with determining the exact population distribution in various areas of the country.
Since most of the social and economic policy planning needs to consider several population characteristics and accurate residency information, the Population and Housing Census is required.
1.3 Objective of the 2000 Population and Housing Census
The Population and Housing Census is conducted in order to collect data on the number and characteristics of all individuals living in the country at the time of the census. The collection includes number and characteristics of individual households.

General concept in field operation
[Sections 2.1-2.2 in the original document are not presented here]
2.3 The method of operation and general principle during the interview
The data collection of the 2000 Population and Housing Census has been done by using the enumerator to interview the head or the member of a household. Therefore, the success of data collection depends upon the effectiveness of the interview conducted by the enumerator. The enumerators must understand clearly the type of work that they are doing and also understand the principle concept of the interview in order to be able to persuade and convince the interviewee to have trust and faith in the interviewer. Trust is important because it results in cooperation and obtaining complete information.
The general principles of the interview which are stated below are regarded as suggestions. They can be further improved to suit the personality of each interviewer in different conditions and environments.
2.3.1 Words of introduction and statement of objectives
The enumerators must introduce themselves to the interviewee who is the head of the household or member of the household. The introduction statement includes the name of the enumerator, the office where he/she represented, and the purpose of visit. Furthermore, the enumerator must show his/her identification card and explain the objective of the 2000 Population and Housing Census. In addition, the enumerator should mention that the information obtained from the census will be used to benefit the general public. An introductory statement and the explanation of objectives must be done with simple wordings that can be easily understood.
Example of words of Introduction and Statement of Objectives:
"I am an officer from the National Statistical Office. I would like to ask you some information of people living in your house such as age, sex, educational level, occupation, and the type and characteristics of the housing. That information will be used by the government for planning purposes, improving the living condition of the population, and will be included into the National Development Plan. All information asked and obtained will be treated as confidential and will not be disclosed to any third parties. When this information is used, it will be coded and represented in form of numbers only."
It is important that the enumerators have their identification card with them at all times. The identification card will verify that they have been designated to this particular assignment.
2.3.2 Dressing/manner and behavior
The enumerators must dress properly and suitable for working in field conditions. They must be polite, cool, simple and friendly and not show any aggressiveness towards the interviewee. Furthermore, they must be patient with the interviewee, in case the latter is uncooperative, criticizes, or complains.
2.3.3 Asking question during the interview
The enumerator must attempt to ask [the questions] to the interviewee exactly as worded in the questionnaire. In the case that the interviewee does not understand the question, then the interviewer should repeat the question. If the interviewee still does not understand, the interviewer must use simple wording to ask the questions, but must be careful that the meaning of the question remains the same as is given in the questionnaire. Avoid leading questions because they will influence the answers obtained. It is important that the enumerator not comment about or criticize the answers of the interviewee, in case that the enumerator feels the answer is wrong or does not reflect the truth. This may occur unintentionally. It is important that the interviewer find other means to make the interviewee give the appropriate answer at all times.
2.3.4 Advise for action in the case no cooperation
If the enumerator interviews any household and finds out that the person living in that house is not cooperative - for example, does not want to meet, does not want to be interviewed, or is giving misleading answers - the enumerator must attempt to again explain the objective and benefit of the census and affirm that all information obtained will be strictly confidential and will not be disclosed to any third parties.
If the person interviewed still refuses to cooperate, the enumerator must report to the supervisor or the provincial/Bangkok metropolis permanent officers, so that they act accordingly.
In the case the enumerator does not get any cooperation due to the fact that the interviewee is not ready - such as they are doing business or attending a traditional ceremony - the enumerator must either wait or proceed to other households before returning to that particular household at a later period.
2.3.5 Reviewing answers in the questionnaire
When the enumerator finishes the interview and has already recorded the data for the given household in all the listing and enumeration forms, it is important that the enumerator review all the questions asked and see that they have all been answered. In the case that the answers are not complete or enumerator is uncertain about the accuracy of the answers, they must repeat those particular questions again. The process of reviewing all asked questions before leaving the interviewed household will avoid returning to that particular household for re-interviewing.
Once the review process is finished, it is important for the enumerator to express their appreciation to the household member for their cooperation with the government in carrying out the census.
2.3.6 Making an appointment for re-interview
Whenever the enumerator visits a house in which he/she did not find the interviewee or could not conduct the interview, the enumerator should make an appointment indicating the specific time and date for the interview and record them completely in the PHC4 form (interview appointment form). The enumerator should either leave the form in the mail box of that particular house, or alternatively ask a neighbor or other people living in household to give it to the head of the household. At the same time, the enumerator should record the date and place of such appointment in the listing form to remind him/herself to return to that particular household for the interview on the appointment date indicated.
2.3.7 When the interviewee answer "I do not know"
If the interviewee answers "I do not know" to any question during the interview this may indicate the following:
b) The interviewee requires time to think about the answer to that specific question.
c) The interviewee does not want to answer the question ever though he/she knows the answer to the question.
d) The interviewee does not know the answer at all.
In this case, the enumerator should ask the specific question again or simplify the question and allocate certain time period for the interviewee to think about the answer. If interviewee still does not know the answer, then the enumerator should accept the answer of "I do not know" as the final answer.
2.4 Legal authority and responsibility of the personnel involved in the data collection
2.4.1 Authority of operation officer in collecting data
Operation officers who worked for the 2000 Population and Housing Census and who have been appointed as the supervisor and enumerator have the right, according to the Statistical Acts of 1965 section 18, to enter the house or personal office in order to fill in the questionnaire, in between the time period of sunrise and sunset, with the purpose of asking the household leader or member of that household to produce evidence or document related to filling out the questionnaire. In this case, the head of the household or the member of such household must be available to those officers. Therefore, the operation officers must bear in mind at all times that the legal right is given to them to enter the household premises between the time period of sunrise and sunset. Entering people's households before or beyond these time period will not be covered by the legal right. In certain cases, the leader of the household may allow the officer to enter their houses at other times apart from the legal time given.
2.4.2 Function and punishment of household leader and operation officer
The head of the household and its members must be available to the field operation officer who enters the housing premises for work at the specific time period, as stated in section 2.4.1
It is the duty of the head of the household and its members to explain facts or give right answers to the officer. Violating or disobeying the legal act mentioned is regarded as an offense, and will be punished according to the Statistical Act of 1965, section 23 and 24, as follows:
Section 23: Anyone who fills out statements or numbers in the given questionnaire when such person realizes that those statements or numbers are false, or gives information or answers that are false to the operation officer or field operator will be imprisoned for up to 3 months, fined up to 500 baht, or receive both a fine and imprisonment, according to section 18.
Section 24: Section 21 states that "All statements or numbers filled in the questionnaire and relating to a specific person or specific case, including the question that needed to be asked, must be treated as strictly confidential". It is prohibited for the operation officer, according to this Statistical Act, to disclose such statements or numbers to anyone not entitled the function and responsibility of working in the census, as stated in the Act, except during the investigation or interrogation for a case where a particular person is prosecuted for providing false information, as stated by the Act. The punishment for violating this act is 6 months imprisonment, a fine of 1,000 baht, or both a fine and imprisonment.
2.4.3 Keeping the collected data secret
All data collected and compiled from the 2000 Population and Housing Census will be evaluated, summarized, and presented for each province, region, and the whole kingdom. They will be published and distributed to all government divisions and institutes, private sectors, and general public. It is prohibited to disclose any information in relation to a specific person, or to disclose any statements or numbers to anyone who is not directly involved in the census process, according to the Statistical Act, section 21. Therefore, the operation officer must be very careful and treat the collected information as strictly confidential. Moreover, the operation officer must explain to the head or the member of the household their protective right according to the law.

2) "Laborer households" [is a location where] at least six people or more (not including the family or household of the owner) are permanently staying in their working place, factory, or any working place where there is no arrangement for them to live separately. For those laborers who live in a place where the factory or any other working place have arranged for them to live separately as an individual family (it may be separate room or a separate house) away from other laborers, their household is classified as a private household. In such places, there may be relatives or other persons living together.

In the case of soldiers, policemen who are staying at the barrack, camp, precinct or police station, if they live separately as a family, count them as private households. If they are not living separately by themselves or with their family, consider it as an instituted household.
For a private household that is located on temple premises, such as the temple treasurer's house, housing which is built on the temple's land, they are counted as private household, not counted as the institute household type temple or monastery.
Some examples are given to help decide the different kinds of households, especially when they are located in the same premises or within a given boundary.

Section on Housing
1. Living place of a household
This refers to a particular structure a household lives in. It can be part of a house or several houses located within the same premises. It also includes space under a bridge where a family is constantly living.
A house that is built as a single structure and it contains a kitchen, garage, and servant's quarter. It is the house in which persons in the same household live together. Alternatively, it refers to several houses located in the same surrounding that have a strong protecting enclosure and where several people of the same household live together.
A Thai style house, where separate houses are joined together with a platform and used as a residence for people from the same household. In the case that separate houses in the Thai style have separate households residing in them, the Thai house is still considered as a single house.
A float house that is built on a pond or reservoir, if separately located, is also considered as a single house.
In the case that a house has no walls, if there are several households living together, the principal household is considered as a single house and other households as other houses.
Townhouse is a building with two units or more attached to one another by common walls on one or more sides. The building can be a single storey or multiple floors. In some cases, the building is located away from the edge of the road, leaving space for car parking or other purposes.
A suite is a group of rooms that are part of a building that can be used by a household as a living place. A suite must consist of a kitchen, toilet and entrance walkway of one own. Examples of suites include apartments, flats, condominiums, mansions, and condotel. [A condotel as known as a condo hotel is a building that is used both as a condominium and hotel].
This is a building, a room or a house used by the household to live in. This particular type of a house has two or more than two units in a row and has one or more than one common wall separating each unit. The building can be a single storey or multiple floors. Row houses or row buildings also include row floating houses of workers of the Royal Irrigation Department.
This is one or more rooms used as a living place for a household in a single house, where there are more than one households living in the house. There may be a kitchen, a toilet or an entrance walkway for the room. Alternatively, all the households may live in separate rooms but share a common kitchen, toilet and the entrance walkway.
If a single house has a principal household (a household that occupies a major portion of the house) and other households that use a partial area of the house, the living place of the principal household is considered a single house and that of other households as rooms in a single house. This allocation occurs regardless of whether a household belongs to the owner or a renter.
This is a room or several rooms within a building, office or storage shade in which a particular household lives. Examples include the living quarters of an office watchman, and a timber warehouse in which laborers live.
These are mobile structures in which a household can live.
These are other living places in which a household can live, but it cannot be a cave, a space underneath a bridge, or a temporary shade where a laborer lives temporarily.
3. Descriptive characteristic of the living place
This refers to a living place classified according to the type of construction material used.
This is any construction that uses concrete, concrete blocks, reinforced flat concrete, or bricks with or without whitewash.
This is a building where the lower level is constructed by using brick whitewash or concrete, while the upper level is constructed using wood. Otherwise, the building is constructed in brick and wood in equal proportions. It includes a house where the lower level is in concrete and the upper level has concrete walls.
This means houses that use mostly permanent constructive materials during construction. Permanent constructive materials include hardwood such as teak wood, snake head wood, red wood etc. Others are concrete, block concrete, reinforced flat concrete, galvanized iron, and fire proofing brick.
The words "mostly permanent constructive materials" should take into consideration five important components of the building such as: post, floor, superstructure, wall and roof. If these constructive components are composed by more than half of permanent materials, the building is classified as constructed using permanent material.
A house in which the post, floor and superstructure are made of hard wood but the wall is made of bamboo and roofing material is made of nipa palm, is considered as mostly made of permanent material.
Not permanent materials are defined as materials which are locally found such as flax, banana leaf, bamboo etc.
A house in which the post and the superstructure are made of hardwood, while the wall and floor are made of bamboo and having nipa palm as a roofing material is considered as constructed using non-permanent materials found locally.
This is the use of rickety such as wood pieces, galvanized iron and [other materials left over] to build a house.
In cases where the living place of the household is composed of several single houses, descriptive characteristic of the living place should be based on the house where the head of the household lives.
This refers to possession of the house for which people living in that particular household are owner, hire purchaser, renters, or live without paying rent because it is part of their wage. In all other cases, the owner allows a person to stay without paying rent.
This is a person in the household with legal right to live in a particular place. In the case that a buyer of a house has not paid the entire cost of the house to the seller but instead transfers his property right as mortgage in a bank, the buyer is considered owner of that particular place.
This is the buying of a living place which is paid for by installments according to a written agreement. When payment is completed, the buyer is considered owner of the living place.
This refers to a person living in the household without being the owner or hire purchaser and has to pay rent to the owner.
This happens when:
a) Rent is part of the wage. Such is the case for officer's housing, night watcher's housing, factory housing, teacher's housing, railway officer's housing, soldier's and policeman's housing, or private housing where a government office or a private company rents for a government officer or governmental personnel. This includes a living quarter in the office or in a building.
b) Staying free of charge, this means living in a house or room without paying any money.
This is a person in the household with legal right to the land property such as:
a) In the case that a buyer of land has not paid the entire cost of the house to the seller but transfers his property right as a mortgage in a bank, the buyer is considered owner of that land.
b) In the case that a person gets a land mortgage from a bank, or has collateral with his name as owner of the land in a document, the person is considered land owner.
d) In the case of a person with a common right in land that has not been divided, the person is considered owner of the land.
This refers to the buying of land and paying in installments according to a written agreement. When payment is completed, then the buyer is considered owner of the land
This refers to construction of a house or other structures on land owned by others and where rent is paid to the owner of the land.
This refers to a situation where the owner of the land allows a person to build a house or any other construction structure in his land free of charge. Not paying rent includes living on land owned by others, in a reserve forest or other public areas etc.

All appliances, utensils, or equipments and tools used for performing careers (such as rented vehicles, refrigerator in a drinking shop, or soda-fountain), if in some cases they are used for private purposes, they are counted as appliances in possession.
If a government vehicle of a particular person with high ranking position in the government is used by only one person, it is counted as a utensil in possession.
Automobile refers to a private car, a rented car or a pickup truck, and does not include a truck, freight car, coach or bus.
Equipment (for agricultural purpose) includes a water pump (in farming), tractor (either four-wheel or the garden type) including implemented equipments such as plough, harrow, cultivator, row and drill planters, seeder and combine harvester.

Guidelines for counting a person in the census
In order to count a person for the census, it is important to consider the place where the person lives. Normally, where a person stays overnight regularly can be used to indicate the place where he/she regularly live.
1. Regular living place of a person in a private household
The place in which a person regularly stays is counted. In the case that a person regularly stays at a different place, consider the following criteria:
a) Count the place at which a person stays most regularly as a regular living place
b) If the times when a person stays in different living places are equal, count the place where a person is staying at the day of the census as the regular living place
1) Mr. A has a house in Bangkok and Nakorn Pathom. However, Mr. A stays in Bangkok more than at Nakorn Pathom. In this case, Bangkok is counted as the regular house of Mr. A.
2) Miss Ice is a school teacher. She lives in a house at her school during weekdays and returns to her house only on weekends. In this case, the regular house of Miss Ice is the house at school
2. Regular or constant living place of a person in a collective household
A temple, barrack, fort, prison, mental hospital, or relieve institute are counted as the regular or constant living places of a monk, novice, nun, on duty soldier, prisoner, patient in the mental hospital, and those who receive relief treatments.
A person who lives in a regular or constant place can be classified as:
a) Permanently staying in a house on the census date.
c) Those who stay temporarily in a house on the day of the census and who do not have any regular house. Alternatively, those who are staying temporarily in a house for over 3 months are also considered permanently staying.
d) Those who move into a house after the date of census with the intention of staying permanently and have never been enumerated at any other place before.
e) Servant, laborer or construction worker who are staying at a particular place for fewer than 3 months.
a) Those who stay permanently in a house, but on the census date, are temporarily absent for fewer than 3 months before the census.
b) Those who are absent for drilling, maneuvering, sailing, went to the forest, hunting, sea fishing, and also sales persons who have not been enumerated in other areas before and are temporarily absent for more than 3 months.
This refers to a person who went abroad for a certain purpose such as for education, training, monitoring or working abroad for a certain time period without any intention of staying abroad permanently even when they are away for over 3 months.
[Tables summarizing criteria for counting persons in private and collective households, p. 53-56, are not presented here]
Recording of listing form
The Listing Form is used as a roll or list of household in each area of the census.

If the house, building or construction structure has a person living there, ask the question for each household living in that particular house, and also ask whether "people who live in that house have their meals together". If the people living in that house have their meals together, put a check mark in column 5, which means that there is one household in that house.
If people who live together in the house do not have their meals together, ask for the detail in order to correctly allocate the number of households in that particular house (see the explanation about households in Chapter 3: Definition, section on population no.13) and record the number of household of that particular house in column C6.

In the case that a particular house or building has a person living, but the enumerator was not able to record the details in column C5-C25 in the PHC1 form, that particular house must be recorded as "not listed". No series number needs to be written in column 10-14
The house that has been assigned as "not listed" is the house where there is a person living on the census date. However, the enumerator is not able to interview [this person] for details throughout the operational period.
In the case that the house assigned as "not listed" had more than one household, and the enumerator was able to list only some households, consider the household that the interviewer could not cover throughout the operation period as "household not listed"
Guideline for action in case there is a "No listed household"
b) Record the time when the listing could not be done as "No listing (first, second, third) time" in column C26
c) After going back for listing a third time or the officer cannot list that particular household throughout the operational period, record "No listing" in column C26

2. Record the letter "a", "b", "c", "d" or "e" in the column C11. If on the Column 10 the series number has already been recorded, record the first letter followed by the beginning letter that was given in the PHC3 form (Job assignment or Job submission form) for every block/village. In the same enumeration district, there will be the same beginning letter, therefore record the beginning letter in column C11 on the line adjacent to household no. 1 in column C10. Record in this manner until you reach the letter "e", then start recording on the letter "a", "b", "c", "d" or "e" respectively. Repeat this procedure again until completing every household that has a series number on column C10.
3. Circle letter "a" in column C11
4. Record the series number of the household in column C12. If you find that a particular household in Column11 has "a" circled, count from no. 1 until completing all households that have "a" circled. The last number of the household that has letter "a" circled will indicate the number of sample private household in that particular block/village.
