Census of Population and Housing refers to the entire process of collecting, compiling, evaluating, analyzing, and publishing data about the population and the living quarters in a country. It entails the listing and recording of the characteristics of each individual and each living quarter as of a specified time and within a specified territory.
Census 2000 is designed to take an inventory of the total population and housing units in the Philippines and to collect information about their characteristics. The census of population is the source of information on the size and distribution of the population as well as information about the demographic, social, economic and cultural characteristics. The census of housing, on the other hand, provides information on the supply of housing units, their structural characteristics and facilities which have bearing on the maintenance of privacy, health and the development of normal family living conditions. These information are vital for making rational plans and programs for national and local development.
The Census 2000 aims to provide government planners, policy makers and administrators with data on which to base their social and economic development plans and programs.
May 1, 2000 has been designated as Census Day for the 2000 Census of Population and Housing (Census 2000), on which date the enumeration of the population and the collection of all pertinent data on housing in the Philippines shall refer.

In the Census 2000, there are basically two types of questionnaires to be used for the enumeration of household members. These are the Common Household Questionnaire (CPH Form 2) and the Sample Household Questionnaire (CPH Form 3). There are procedures for selecting those households to whom CPH Form 3 will be administered. All enumerators are required to strictly follow these procedures.
The sampling rate or the proportion of households to be selected as samples within each Enumeration Area (EA), varies from one EA to another. It can either be 100%, 20% or 10%. If the sampling rate applied to an EA is 100%, it means that all households in that EA will use CPH Form 3. If it is 20% or 10%, it means that one-fifth or one-tenth, respectively, of all households will use CPH Form 3, while the rest will use CPH Form 2.
The scheme for the selection of sample households is known as systematic sampling with clusters as the sampling units. Under this scheme, the households in an EA are grouped in clusters of size 5. Clusters are formed by grouping together households that have been assigned consecutive serial numbers as they are listed in the Listing Page.
Dates of collection
Mode of data collection
Data collection supervision
Field supervision for the Census 2000 commenced right after the last level of training. Throughout the enumeration period NSO field supervisors, Department of Education, Culture and Sports (now DepEd) personnel assigned as Census Area Supervisor (CAS) and Team Supervisor (TS), and other personnel assigned as supervisors did fieldworks to supervise the conduct of enumeration and check if the enumerators were at work.
To ensure that the enumeration procedures were properly carried out, each supervisor including the CAS and TS were asked to accomplish CPH Form 13 or the Reinterview/Spot-check form.
To check the accuracy of the data collected, the supervisors reviewed the CPH questionnaires accomplished by the enumerators.
The questionnaires for 2000 Census of Population and Housing were basically patterned from previous censuses except that it should be in Intelligent Character Recognition (ICR) format. The basic questionnaires designed for this undertaking were as follows:
CPH Form 1 - Listing Page
This is a sheet wherein the buildings, housing units, households and institutional living quarters within an enumeration area (EA) are listed. Other information pertaining to the population of households and institutional living quarters are also recorded on this form.
CPH Form 2 - Common Household Questionnaire
This is the basic census questionnaire which will be used for interview and for recording of information about the common or non-sample households. This questionnaire gathers information on the following demographic and social characteristics of the population: relationship to household head, family nucleus, date of birth, age, birth registration, sex, marital status, religious affiliation, disability, ethnicity, residence five years ago and highest educational attainment. This also gathers information on building and housing unit characteristics.
CPH Form 3 - Sample Household Questionnaire
This is the basic census questionnaire, which will be used for interview and for recording of information about the sample households. This questionnaire contains the same questions as in CPH Form 2 and additional questions, namely: citizenship, language, literacy, school attendance, type of school, place of school, usual activity/occupation, kind of business/industry, place of work and some items on fertility. It also has additional questions on household characteristics and amenities and residence five years ago.
CPH Form 4 - Institutional Population Questionnaire
This questionnaire records information about persons considered part of the institutional population. It contains questions on residence status, date of birth, age, sex, marital status, religious affiliation, disability, ethnicity, and highest educational attainment.
CPH Form 5 - Barangay Schedule
This questionnaire gathers indicators to update the characteristics of all barangays which will determine its urbanity.
CPH Form 6 - Notice of Listing/Enumeration
This is a sticker that must be posted in a very conspicuous place, preferably in front of the house or gate of the building after listing and interviewing. This sticker indicates that the Building/Housing Unit/Household has already been enumerated.
CPH Form 7 - Common Household Questionnaire SAQ Instructions
This form contains the detailed instructions on how to fill out CPH Form 2. It accompanies CPH Form 2 that must be distributed to households who will answer the form themselves, such as those in designated Self-Administered Questionnaire (SAQ) areas or those where three callbacks or four visits have been made.
CPH Form 8 - Institutional Population Questionnaire SAQ Instructions
This form describes the instructions on how to accomplish CPH Form 4 - Institutional Population Questionnaire. It accompanies CPH Form 4 that must be distributed to head of institutions who will accomplish the form.
CPH Form 9 - Appointment Slip
This form will be used to set an appointment with the household head or any responsible member of the household in case the enumerator was not able to interview anybody during his/her first visit or second visit. The enumerator must indicate in this form the date and time of his/her next visit.
Blank Barangay Map
This form will be used to enlarge map of each block of an EA/barangay especially if congested areas are being enumerated.
The questionnaires were developed in English and were translated to major dialects: Bicol, Cebuano, Hiligaynon, Ifugao, Ilocano, Kapampangan, Tagalog, and Waray.
Processing of census forms consisted of manual and machine data processing. Prior to machine processing at the Data Capture Center (DCC), census questionnaires were subjected to manual processing done by Census 2000 Provincial Project Staff (PPS 2000) at the provincial office. Manual processing included several procedures such as the verification of geographic identification and completeness of forms, document preparation, and packaging of forms for transmission to respective DCC for the second phase operation. The DCC was primarily created to handle data capture and forms processing in order to come up with image and text files. These files will be used for further processing in order to come up with statistical tables.
