Population and Housing Census [hh/popcen]
POPCEN 2015 is the 14th census of population conducted in the country since the first census in 1903. It is the third mid-decade census undertaken in the country. The previous mid-decade censuses were conducted in 1995 and 2007.
Philippines Population Census 2015 was designed to take an inventory of the total population in the country and collect information about its characteristics. The census of population is the source of information on the size, distribution, and composition of the population in each barangay, city/municipality, province, and region in the country, as well as information about its demographic, social, and economic characteristics. These indicators are vital in the formulation of rational plans and programs towards national and local development.
Specifically, POPCEN 2015 gathered data on:
- size and geographic distribution of the population;
- population composition in terms of age, sex, and marital status;
- religious affiliation;
- school attendance, literacy, highest grade/year completed, and technical/vocational course obtained;
- usual activity/occupation, and whether overseas worker for members 15 years old and over;
- registration of birth and death;
- household-level characteristics such as fuel used for lighting and source of water supply for drinking and cooking;
- housing characteristics such as the type of building, construction materials of the roof of the building, construction materials of the outer walls of the building/housing unit, and tenure status of the housing unit/lot; and
- barangay characteristics such as the presence of selected facilities and establishments; and presence of informal settlers, relocation areas, and in-movers in the barangay due to natural and man-made disasters.
August 1, 2015 was designated as Census Day for the POPCEN 2015, on which date the enumeration of the population in the Philippines was referred. For the purpose of this census, all information collected about the population were as of 12:01 a.m., Saturday, August 1, 2015.
Enumeration lasted for about 25 days, from 10 August to 6 September 2015. In some areas, enumeration was extended until 15 September 2015 for large provinces.

Survey instrument
Listed below are the basic census forms that were used during the field enumeration:
-
CP Form 1 - Listing Booklet
This booklet was used to list the buildings, housing units, households, and ILQs within an EA. It was also used to record other information such as the address of the household head or ILQ, total population, and number of males and females corresponding to each household and ILQ listed. -
CP Form 2 - Household Questionnaire
This four-page questionnaire was used to record information about the households. Specifically, this form was used to gather information on selected demographic and socio-economic characteristics of the population and some information on housing characteristics. -
CP Form 4 - Institutional Population Questionnaire
This four-page questionnaire was used to record information on selected demographic and socio-economic characteristics of the population residing in ILQs. -

Listed below are the major administrative and accomplishment forms that were also used to facilitate data collection and supervision, and monitoring of enumeration and personnel:
-
Mapping Form
This form was used to plot buildings, either occupied by households or vacant, ILQs and important physical landmarks in the area. It was also used to enlarge a map or a block of an EA/barangay if the area being enumerated is too large or congested.
CP Form 1 - Listing Booklet -
CP Form 6 - Notice of Listing/Enumeration
This form is a sticker. After listing and interviewing a household or ILQ, this sticker was posted in a very conspicuous place, preferably in front of the house or at the gate of the building. This form was used for control and monitoring purposes as its presence indicates that a particular housing unit or ILQ had already been listed/interviewed. -
CP Form 9 - Appointment Slip to the Household/Institution/Barangay Official
This form was used to set an appointment with the household head or any responsible member of the household or manager of an ILQ, in case the EN failed to interview any respondent in the household or ILQ during his/her visit.

I. PERSONNEL INVOLVED IN THE SUPERVISION
The PSA CO and FO personnel directly supervised the conduct of enumeration. In the region, the Regional Director (RD) and his/her staff conducted field visits in the provinces within his/her jurisdiction. At the provincial level, the Provincial Statistics Officer (PSO) and his/her staff supervised the census operation in the cities/municipalities and barangays within the province.
Aside from the PSA personnel, hired personnel were also tapped to carry out supervisory functions. In a city/municipality, close field supervision was the responsibility of the head CASs, hired CASs and hired TS within their respective areas of assignment. On average, a hired CAS was required to supervise five TSs, while a TS was assigned to supervise about four ENs.
II. SUPERVISORY ACTIVITIES
PSA CO and FO, and hired supervisors were required to re-interview some households and conduct spotchecking activities in the area under their jusrisdiction. They were also tasked to observe some ENs who were conducting interview. The supervisors were then asked to discuss with the EN their observations to improve data collection by correcting the ENs' mistakes in asking questions, observing skipping patterns, and others. For the re-interview, spotchecking, and observation activities, the supervisor used CP Form 12.
The supervisors were also required to perform field editing of the accomplished questionnaires either manually or using CAFES, and discuss with the ENs the issues with respect to inconsistencies, item nonresponse, and invalid entries.
Moreover, some supervisors were tasked to collect the coordinates of the building/housing units of the housholds whose interviews by the EN where observed by them, using a Global Positioning System (GPS) receiver.
A weekly meeting between the supervisors and ENs was done to discuss the problems encountered during the census enumeration. It was also the time when supervisors reviewed the accomplished questionnaires before these were submitted to the PO.
I. CONDUCT OF PRETESTS AND PILOT CENSUS
In preparation for the actual conduct of the POPCEN 2015, four pretests and a pilot census were conducted in 2014.
PRETESTS:
Pretest 1 - conducted in Rosario, Cavite to test the time devoted to interviewing and in filling-out of the questionnaires, and the wordings and sequence of questions/flow of interview.
Pretest 2 - conducted in Rodriguez, Rizal, to determine the actual interview time in answering the questions revised in CP Forms 1 and 2. Moreover, the pretest also determined the actual time consumed in travelling from one household to the next household. The number of households interviewed was used in determining the average output for areas with the same characteristics.
Pretest 3 - conducted in NCR I, specifically in the area where there were condominiums. The average output for covering such multi-unit residential buildings was tested. Likewise, this pretest recommended strategies in enumerating households in high-rise condominiums.
Pretest 4 - conducted in Rosario, Cavite. This pretest tested the questions and strategy in covering relocation areas where households displaced by Typhoon Yolanda were transferred.
PILOT CENSUS:
Pilot areas:
Luzon: NCR District I and Cagayan
Visayas: Cebu, Eastern Samar, Leyte, Samar
Mindanao: Davao Oriental
The pilot census was conducted in August 2014, a year before the actual census operation to test every phase of the census operation - workload analysis and cost estimation; questionnaires, forms, and manuals; printing and delivery/distribution of the questionnaires and forms; training, hiring of enumerators, supervisors, and processors; actual enumeration and supervision; and data processing. The pilot census was basically designed to test the procedures and systems to be used in the census enumeration and supervision, and detect and correct any weakness or defficiency in the manual and machine processing systems and procedures before the actual operation is conducted. The experiences in the pilot census resulted to some revisions in the questionnaires, manuals, and in the data processing procedures. Further, in the case of Visayas which included in Typhoon Yolanda affected areas, the pilot censuses served as basis for re-computation of workload in anticipation of possible movements of persons/households due to evacuation.
II. DATA COLLECTION INSTRUMENTS
All households, housing units, and ILQs were listed using CP Form 1 (Listing Booklet). Members of the household were enumerated using CP Form 2 (Household Questionnaire). For households which opted to accomplish the questionnaire themselves CP Form 2 together with CP Form 7 (Household Self-Administered Questionnaire Instructions) were provided. Persons living in ILQs or the institutional population were enumerated using CP Form 4 (Institutional Population Questionnaire). Similarly, especially for large institutional population, CP Form 4 with CP Form 8 (Institutional Population Self-Administered Questionnaire Instructions) were provided to managers or administrators of the ILQ for self-accomplishment.
Information about the characteristics of the barangay, facilities, and establishments therein, among others, were collected using CP Form 5 (Barangay Schedule).
III. PERSONNEL INVOLVED IN THE DATA COLLECTION
Enumerators (EN), team supervisors (TS), and Census Area Supervisors (CAS) were all hired by PSA. Regular staff of the PSA field offices were designated as Head CAS. Hired CAS assisted the Head CAS.
An EN was assigned to cover one or more enumeration areas (EA) or barangays depending on the workload, average daily output, and mandays computed. A TS was assigned to supervise about four ENs. In turn, a hired CAS was responsible for a group of five teams, with each team consisting of one TS and four ENs. Moreover, Head CASs supervised a group of hired CASs.
IV. CONDUCT OF TRAINING
Training of personnel for the POPCEN 2015 is essential to enable these personnel to effectively carry out the specific tasks assigned to them. Training at different levels were conducted simultaneously and as systematically as possible to come up with a common knowledge on definitions, concepts, and operational procedures that will be used in the enumeration, supervision, and data processing.
The training programs conducted for the POPCEN 2015 were the following:
- Training on enumeration and field operations in four levels: first level or task force for PSA Central Office (CO), Regional Director and selected Provincial Statistics Officers (PSO); second level for selected PSOs and Field Office (FO) staff; third level for hired CASs; fourth level for TSs, ENs, and other census peronnel;
- Training on Progress Monitoring System (PMS) and Evaluation of PMS Reports for regional and provincial statisticians were in two levels, the first and second level trainings;
- Training on Manual Processing and Tracking, Receipt and Control System (TRACS) in three levels: first level for selected CO and FO personnel; second level for regional/provincial statisticians and staff; third level for hired processors, and Receipt and Control Clerks (RCC); and
- Training on machine processing, scanning, electronic coding, and data encoding of CP Forms 2, 4, and 5, and archiving of CP Form 1 and maps in three levels; first level for selected FO staff; second level for regional statisticians, provincial statisticians; third level for machine processors.
V. SUPERVISION DURING ENUMERATION
Field supervision is primarily aimed at ensuring the correct implementation of procedures and accurate data collection. Thus, field supervisors had systematically undertaken all measures of quality control activities. The following quality control procedures were carried out during the supervision of the conduct of census:
a. Scrutiny or editing of the questionnaires (CP Forms 1, 2, 4, and 5) in the field by the ENs to check for consistency, correctness, and completeness of responses.
b. Scrutiny or editing of questionnaires by supervisors during field work using Computer-Aided Field Editing System (CAFES) which covered items P1 to P12 of all accomplished CP Form 2.
c. Checking randomly by the supervisors the consistency of the number of households and ILQs, the counts for males and females in CP Forms 2 and 4 against the corresponding numbers/entries in CP Form 1 and CP Form 10 (Daily Accomplishment Report of Enumerator).
d. Examination of the questionnaires for dubious and fictitious names/entries.
e. Re-interview at random households that were already enumerated by the ENs to ensure the accuracy of information gathered.
f. Review of maps as to orientation and boundaries and checking if the buildings, ILQs, and important physical landmarks were properly plotted on the maps.
g. Obtaining and comparing the average actual output per day of the ENs with the expected output per day to monitor/assess the progress of the EN's work.
h. Checking for indications of padding or under enumeration.
VI. PROGRESS MONITORING SYSTEM
The PMS was designed to provide the required information for monitoring the progress of enumeration and evaluating the completeness/coverage of the census at the national, regional. provincial, city/municipality, barangay, and EA levels. The PMS assessed the overall situation of the enumeration in terms of percentage of coverage.
Preparation of reports and documents pertaining to the PMS started with the submission of CP Form 1 by the ENs to the TS after the enumeration has been completed in an EA. The information in CP Form 1 that were consistently checked with CP Forms 2 and 4 were sent through Short Messaging Service (SMS) or text messaging by the TS. PMS reports were generated based on SMS data sent which included the number of EAs and barangays which have been completely enumerated; count of household and population covered; and number of areas with GPS coverage. These reports were generated and used by Provincial Statistical Office (PO), Regional Statistical Services Office (RSSO), and CO to monitor the progress of enumeration and assess the coverage of the census.
VII. INTERVIEW TIME
On average, the duration of interview in a household lasted for about 15 to 20 minutes.
VIII. DAILY AVERAGE OUTPUT
The average output per day or the average number of households enumerated per day varied depending on the characteristics of the EA/barangay in terms of terrain, accessibility, urbanity, dispersion of households, weather, availability of transportation facilities, and prevailing socio-economic and political conditions in the area.
IX. LANGUAGES USED IN THE INTERVIEW
The census questionnaires were prepared in English and translated into different languages, such as Tagalog, Ilocano, Pangasinan, Ibanag, Kapampangan, Cuyunon, Rombloanon, Bikol/Bicol, Masbateño, Hiligaynon, Cebuano/Bisaya, Waray, Chavacano, Surigaonon, Kamayo, Maguindanaon, Maranao, and Tausug. Data collectors were instructed to use these translation guides, if needed in interviewing the household. The translation guides can be found at the back of the EN's Manual.
Data processing
Data editing of entries in the accomplished questionnaires/data files was undertaken at every phase of POPCEN 2015 to ensure the quality of data. This was done during:
- enumeration, when enumerators (EN) were required to check their accomplished questionnaires for completeness and consistency of entries/data;
- supervision, when the supervisors performed field editing of accomplished questionnaires of the ENs;
- submission and review of questionnaires by the supervisors during the weekly meeting or during submission of questionnaires for the completed EA;
- machine editing in the field using CAFES, after every observed interview of an EN, or at the end of the day and sometimes during the weekly meeting;
- manual processing at the Data Processing Centers (DPC 2015) of POs;
- machine processing at the RSSO and selected POs; and
- further processing at the Population and Housing Census Division (PHCD) using census processing systems developed by the Systems Development Division (SDD) of PSA-CO.
Data appraisal
The evaluation of population counts and households from the POPCEN 2015 was carried out during the enumeration period using counts generated from the PMS.
The RSSO was responsible for the evaluation of POPCEN 2015 counts for the region, and the PO for the province. The reports generated from the Quick Count System (QCS) were used as bases in evaluating the population counts. The evaluation of population counts at the FO started once all CP Form 1 had already been encoded through the QCS. The QC Report generated by the PO was used in evaluating/monitoring the completeness and coverage of census in each barangay and city/municipality in the province. The report also showed the comparative counts of households and population based on the 2010 CPH and POPCEN 2015.
Parallel monitoring and evaluation were done at the CO, particularly at the PHCD.
