Study notes
POPCEN 2007 was designed to take an inventory of the total population 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, and economic characteristics. These information are vital for making 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 characteristics of the population in each barangay, city/municipality, province, and region in the country. This census included the gathering of basic information on demographic and other socio-economic characteristics.
General Objectives
POPCEN 2007 aims to provide government planners, policy makers, and administrators with data on which to base their social and economic development plans and programs.
Specific Objectives
POPCEN 2007 aims to:
-obtain comprehensive data on the size of the population of the Philippines and its geographic distribution;
-gather data on the population composition in terms of age, sex, and marital status;
-gather data on highest grade/year completed, school attendance, and place of school;
-collect information on usual occupation and place of work;
-collect information on housing characteristics, particularly construction materials of the roof and outer walls, and tenure status of the lot;
-collect information about households in temporary relocation areas; and
-obtain information on the characteristics of the barangay for use as basis in urban-rural classification of these barangays.
August 1, 2007 has been designated as Census Day for POPCEN 2007, on which date the enumeration of the population in the Philippines was referred. For the purpose of this census, all information about the population were collected as of 12:01 a.m., Wednesday, August 1, 2007.

Data collection supervision
I. PERSONNEL INVOLVED IN THE SUPERVISION
The NSO Central and Field Office personnel directly supervised the conduct of enumeration. In the region, the Regional Director and his/her staff were responsible for field visits in their respective provinces. At the provincial level, the Provincial Statistics Officer and his/her staff were responsible for supervision in cities/municipalities and barangays in their respective jurisdiction.
Aside from the NSO personnel, hired personnel were also tapped to augment supervisory functions. In a city/municipality, close field supervision was the responsibility of the Census Area Supersivor (CAS) assigned in the area. As mentioned earlier, on the average, the CAS was required to supervise seven Team Supervisor (TS). On the other hand, as a general rule, a TS was assigned to supervise five ENs. For a city/municipality with less than five enumerators (ENs), the CAS acted as the TS.
II. SUPERVISORY ACTIVITIES
NSO Central Office, Field Office, and hired supervisors were required to carry out re-interview of households and conduct spotchecking of the area and households with and without CP Form 6. Also, supervisors were required to observe the ENs in interviewing the households. The supervisor and the EN discussed the observation to improve data collection and to correct mistakes in asking questions, following skipping pattern, and others. For the re-interview, spotchecking, and observation activities, the supervisor used CP Form 12.
Further, the supervisors were also required to perform field editing of the accomplished questionnaires and discuss the issues with respect to inconsistencies, item non-response, and invalid entries in the accomplished questionnairres.
A weekly meeting with the supervisors and ENs was done to discuss problems encountered in the conduct of census and for the supervisors to review the accomplished questionnaires before submitting these questionnaires to the NSO Field Office.

Data Appraisal
Other forms of data appraisal
EVALUATION OF POPULATION COUNTS FROM THE 2007 CENSUS OF POPULATION
The evaluation of the counts of population and households from the 2007 Census of Population (POPCEN 2007) was carried out rigorously during the enumeration period using counts based from the Progress Monitoring System (PMS) reports sent to the Central Office (CO) through Short Message Service (SMS) or text messaging. The objective is to identify areas with coverage errors, that is, omission of households or persons and enumeration of households or persons more than once, and to correct these errors immediately. The Enumerator's Accomplishment/PM Reports (CP Form 10) were used as input to the PMS for POPCEN 2007. It generated reports for use by the NSO Provincial Offices, Regional Offices, and Central Office in monitoring the progress of enumeration and in identifying areas with possible coverage errors. The evaluation continued after the enumeration period using counts from Regional Data Processing Centers (RDPC).
EVALUATION OF COUNTS AT THE NSO FIELD OFFICES
The Regional Office (RO) was responsible for the evaluation of the POPCEN 2007 counts for the region while the Provincial Office (PO) was responsible for the province. The computerized reporting through the PMS facilitated the evaluation at the PO and the RO. The PMS generated various reports which include the EA Progress Enumeration Report (PMS Report 3). This report shows the counts of population of males and females and number of households by EA and the status of enumeration in each EA or barangay based on the information from CP Form 10. Another PMS report generated at the PO is the Barangay Coverage Report (PMS Report 4). This report was used to evaluate the acceptability of the reported counts for the following indicators, computed up to the barangay level:
a. Household and population counts
b. Demographic indicators
- annual population growth rate
- percent change in the number of households
- average household size
c. Difference between 2007 and 2000 institutional population
d. Number and percent of EAs completed
The field offices investigated areas with demographically implausible growth rates, and questionnable values in any of the cited indicators.
EVALUATION AT THE CENTRAL OFFICE
Parallel monitoring and evaluation were done at the Central Office particularly at the Household Statistics Department (HSD). The information used for the evaluation by HSD were:
a. POPCEN 2007 counts up to the barangay level generated by RDPCs;
b. average annual population growth rates for the provinces and cities/municipalities for the periods 1980-1990, 1990-1995, 1995-2000 and for all geographic levels, that is, including barangay level, for the period 2000-2007;
c. sex ratio for the provinces and cities/municipalities for the year 2000, and for all geographic levels for the year 2007;
d. average household size for all geographic levels, for the years 1990, 1995, 2000, and 2007;
e. percent change of population between census years 1995 and 2000, and 2000 and 2007 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, and 2000 and 2007, for all geographic levels.
Acceptable or demographically plausible values for these indicators, as well as the expected direction of their changes over time are specified in the Field Operations Manual (FOM) (page 86) of POPCEN. The demographic indicators for each geographic area were evaluated using the procedures also contained in the FOM. Explanations were sought if a particular indicator fell outside the acceptable range of values, or if the observed change in the indicator deviates from the expected demographic trend. The Regional Director submitted to the CO the explanations of the POs in his/her region for areas with census results that were considered questionable by the CO based on its independent evaluation.
A more thorough procedure of evaluation was employed for barangays suspected of having under-enumerated population or padded or fabricated population. Careful scrutiny of questionnaires for these barangays was carried out following the procedures discussed in pages 86-88 of the FOM. In extreme cases wherein the result of the scrutiny of questionnaires confirmed that under-enumeration or padding or fabrication of population was committed, field verification became necessary. Teams composed of Statisticians from the CO, the PSOs and Statisticians of concerned provinces conducted field verification in areas suspected of having been under-enumerated or over-enumerated.
