Study notes
POPCEN 2015 was designed to take an inventory of the total population in the Philippines and collect information about its characteristics. The census of population is the source of information on the size, distribution, and composition of the population as well as information about its demographic, social, and economic characteristics. These information are vital in the formulation of rational plans and programs towards national and local development.
The said census undertaking involved collecting, compiling, evaluating, analyzing, publishing, and disseminating data on the population count and selected demographic and socio-economic characteristics of the population in each barangay, city/municipality, province, and region in the country.
General Objectives:
The main objective of the POPCEN 2015 was to provide government executives, policy makers, and planners with population data, especially updated population counts of all barangays in the country, on which to base their social and economic development plans, policies, and programs.
The specific objectives of the POPCEN 2015 were to gather 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.

Data collection supervision
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.

Data Processing
Data editing
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:
1. enumeration, when ENs were required to check their accomplished questionnaires for completeness and consistency of entries/data;
2. supervision, when the supervisors performed field editing of accomplished questionnaires of the ENs;
3. submission and review of questionnaires by the supervisors during the weekly meeting or during submission of questionnaires for the completed EA;
4. 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;
5. manual processing at the Data Processing Centers (DPC 2015) of POs;
6. machine processing at the RSSO and selected POs; and
7. 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
Other forms of data appraisal
EVALUATION OF POPULATION COUNTS FROM THE 2015 CENSUS OF POPULATION
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 reports generated using the PMS were the following:
1. PM Report 1 - Progress of Enumeration by Enumeration Area
This report provided information on the percentage of EAs where the enumeration was completed relative to the total number of EAs. It also showed the status of enumeration in each EA, that is, whether the enumeration is already completed or is still ongoing.
2. PM Report 2 - Progress of Enumeration by Enumeration Area with Total Number of Households and Total Population
This report showed which EAs were already completely enumerated as of the date the report was generated. It also showed the percentage of EAs in a barangay, city/municipality or province that had already completed the census taking. For the completely enumerated EAs, the number of households and population count could be compared with the corresponding 2010 CPH counts and the counts estimated for each barangay in the province for August 2015, which the CO provided to the FO for their workload analysis. Any significant deviation in the counts based on the POPCEN 2015 from the 2015 CPH counts or estimates for August 2015 were investigated.
3. PM Report 3 - Number of Enumeration Areas with Reported GPS Coordinates
This report showed the percentage of EAs with reported GPS coordinates and number of housing units with GPS coordinates. It also provided information on the number of EAs visited by the CAS when he/she observed the household interviews conducted by the EN.
EVALUATION OF COUNTS AT THE PSA FIELD OFFICES
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. QC Report contained the following information:
a. Number of households: 2010 and 2015
b. Total population: 2010 and 2015
c. Household population: 2010 and 2015
d. Institutional population: 2010 and 2015
e. Annual population growth rate: 2010-2015
f. Change in the humber of households: 2010-2015
g. Average household size: 2010 and 2015
h. Change in the count of institutional population: 2010-2015
i. Sex ratio: 2010 and 2015
The FOs investigated areas with demographically implausible growth rates, and questionnable values in any of the aforecited indicators.
EVALUATION OF POPULATION COUNTS AND NUMBER OF HOUSEHOLDS AT THE CENTRAL OFFICE
Parallel monitoring and evaluation were done at the CO, particularly at the PHCD. The information used in the evaluation of population counts and number of households were the following:
a. POPCEN 2015 population counts down to the barangay level;
b. average annual population growth rates for the provinces and cities/municipalities for the periods 1995-2000, 1995-2007, 2000-2007, 2007-2010, 2000-2010, and 2010-2015 at all geographic levels, that is, down to barangay level;
c. sex ratio in the provinces and cities/municipalities for the year 2010, and for all geographic levels for the year 2015;
d. average household size for all geographic levels, for the year 2010;
e. percent change of population between census years 1995 and 2000, 2000 and 2007, 2007 and 2010, and 2000 and 2010 for all geographic levels; and
f. difference in the household population, number of households, and institutional population between census years 1990 and 1995, 1995 and 2000, 2000 and 2007, 20007 and 2010, and 2000 and 2010 for all geographic levels.
Acceptable or demographically plausible values for the aforementioned indicators, as well as the expected direction of their changes over time were specified on page 86 of the POPCEN 2015 Field Operations Manual (FOM). The demographic indicators for each geographic area were evaluated using the procedures also contained in the said FOM. Explanations from PSA field offices were sought if a particular indicator fell outside the acceptable range of values, or if the observed change in the indicator deviated from the expected demographic trend.
A more thorough procedure of evaluation was employed for barangays suspected of having under-enumerated population and padding or fabrication of figures. Careful scrutiny of questionnaires for these barangays was carried out following the procedures discussed in pages 131 and 132 of the FOM. In extreme cases, when the result of the scrutiny of questionnaires confirmed that under-enumeration, padding or fabrication of population was committed, field verification was made. Teams composed of statisticians from the CO and the PSO and statisticians of concerned provinces conducted field verification in areas suspected of having been under-enumerated or over-enumerated population.
EVALUATION OF DEMOGRAPHIC AND SOCIOECONOMIC CHARACTERISTICS
The evaluation of demographic and socioeconomic characteristics was carried out based on the following:
1. Evaluation at the FO
Evaluation of marginal and consistency tables

EVALUATION OF BARANGAY CHARACTERISTICS
Information gathered from CP Form 5 was sent to FO in excel format for field verification, evaluation and confirmation. The file contained comparison of information on barangay facilities and characteristics, kinds of establishment in the barangay, informal settlers, presence of relocation area, and in-movers based on 2000 CPH, POPCEN 2007, CPH 2010 and POPCEN 2015. The confirmed file undergone further processing at CO.
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 reports generated using the PMS were the following:
1. PM Report 1 - Progress of Enumeration by Enumeration Area
This report provided information on the percentage of EAs where the enumeration was completed relative to the total number of EAs. It also showed the status of enumeration in each EA, that is, whether the enumeration is already completed or is still ongoing.
2. PM Report 2 - Progress of Enumeration by Enumeration Area with Total Number of Households and Total Population
This report showed which EAs were already completely enumerated as of the date the report was generated. It also showed the percentage of EAs in a barangay, city/municipality or province that had already completed the census taking. For the completely enumerated EAs, the number of households and population count could be compared with the corresponding 2010 CPH counts and the counts estimated for each barangay in the province for August 2015, which the CO provided to the FO for their workload analysis. Any significant deviation in the counts based on the POPCEN 2015 from the 2015 CPH counts or estimates for August 2015 were investigated.
3. PM Report 3 - Number of Enumeration Areas with Reported GPS Coordinates
This report showed the percentage of EAs with reported GPS coordinates and number of housing units with GPS coordinates. It also provided information on the number of EAs visited by the CAS when he/she observed the household interviews conducted by the EN.
EVALUATION OF COUNTS AT THE PSA FIELD OFFICES
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. QC Report contained the following information:
a. Number of households: 2010 and 2015
b. Total population: 2010 and 2015
c. Household population: 2010 and 2015
d. Institutional population: 2010 and 2015
e. Annual population growth rate: 2010-2015
f. Change in the humber of households: 2010-2015
g. Average household size: 2010 and 2015
h. Change in the count of institutional population: 2010-2015
i. Sex ratio: 2010 and 2015
The FOs investigated areas with demographically implausible growth rates, and questionnable values in any of the aforecited indicators.
EVALUATION OF POPULATION COUNTS AND NUMBER OF HOUSEHOLDS AT THE CENTRAL OFFICE
Parallel monitoring and evaluation were done at the CO, particularly at the PHCD. The information used in the evaluation of population counts and number of households were the following:
a. POPCEN 2015 population counts down to the barangay level;
b. average annual population growth rates for the provinces and cities/municipalities for the periods 1995-2000, 1995-2007, 2000-2007, 2007-2010, 2000-2010, and 2010-2015 at all geographic levels, that is, down to barangay level;
c. sex ratio in the provinces and cities/municipalities for the year 2010, and for all geographic levels for the year 2015;
d. average household size for all geographic levels, for the year 2010;
e. percent change of population between census years 1995 and 2000, 2000 and 2007, 2007 and 2010, and 2000 and 2010 for all geographic levels; and
f. difference in the household population, number of households, and institutional population between census years 1990 and 1995, 1995 and 2000, 2000 and 2007, 20007 and 2010, and 2000 and 2010 for all geographic levels.
Acceptable or demographically plausible values for the aforementioned indicators, as well as the expected direction of their changes over time were specified on page 86 of the POPCEN 2015 Field Operations Manual (FOM). The demographic indicators for each geographic area were evaluated using the procedures also contained in the said FOM. Explanations from PSA field offices were sought if a particular indicator fell outside the acceptable range of values, or if the observed change in the indicator deviated from the expected demographic trend.
A more thorough procedure of evaluation was employed for barangays suspected of having under-enumerated population and padding or fabrication of figures. Careful scrutiny of questionnaires for these barangays was carried out following the procedures discussed in pages 131 and 132 of the FOM. In extreme cases, when the result of the scrutiny of questionnaires confirmed that under-enumeration, padding or fabrication of population was committed, field verification was made. Teams composed of statisticians from the CO and the PSO and statisticians of concerned provinces conducted field verification in areas suspected of having been under-enumerated or over-enumerated population.
