Census of Philippine Business and Industry 2006, Agriculture, Hunting and Forestry Sector, and Fishing Sector
Agriculture, Hunting and Forestry Sector, and Fishing Sector
The 2006 Census of Philippine Business and Industry (CPBI) is one of the designated statistical activities undertaken by the National Statistics Office (NSO). It sought to collect and generate information on the levels, structure and trends of economic activities in the entire country. Data collected from the census will served as a benchmark for the measurement and comparison of national, regional and provincial economic growth.
The data collected from the 2006 CPBI will constitute bases upon which the government and private sectors can formulate policies and evolve economic development plans. Specifically, the census data are used in constructing national and regional income accounts of the Philippine economy; formulating and monitoring plans and policies in the attainment of national and regional economic goals; determining and comparing regional and provincial economic structures and performances; providing updates for the frame of establishments; and conducting market research and feasibility studies.
The scope of the census consisted of 14 sectors of the Philippine economy as classified in the amended 1994 Philippine Standard Industrial Classification (PSIC). All information collected from the census refers to calendar year 2006 except for employment data which is as of 15 November 2006.
This metadata, however, contains the documentation of two sectors namely: Agriculture, Hunting and Forestry sector and Fishing sector classified as major divisions A and B in the amended 1994 PSIC. Data collected are on employment, compensation, revenue, subsidies, cost, fixed assets, intangible assets, capital expenditures and inventories. It also includes the procedures undertaken in all phases of the operation, scope and coverage, sampling design, publication volume, copy of questionnaire used, and other administrative and informative documents related to the census operation.

The 2006 CPBI used stratified systematic sampling with five-digit PSIC or groups of five-digit PSIC and/or four-digit PSIC or groups of four-digit PSIC and/or three-digit PSIC or groups of three-digit PSIC serving as first stratification variable and total employment as the second stratification variable.
The sampling design for the 2006 CPBI consists of the following:
a. Determination of geographic domain
b. Determination of industry domain
c. Determination of employment strata
d. Determination of sampling unit
e. Determination of sample size
f. Sample allocation
g. Sample selection.
For the complete details of the above-mentioned procedures and sampling frame used, refer to technical documents Section 'Sampling Design' and 'Frame of Establishments', respectively, of the Publication Volume.
Data of non-responding establishments were imputed manually and electronically based on established imputation methods. Sources of information were from previous reports of the same establishment, or from report of other responding establishment with similar characteristics, financial statements filed at Securities and Exchange Commission. 'Hot and cold deck' imputation methods were used for partial and total nonresponse.
The total number of sample establishments for the agriculture, hunting and forestry sector is 1,605. This is broken down by establishments size, that is, 651 for establishment with total employment of 20 and over while it is 954 for establishment with total employment of less than 20.
The overall response rate is 91.7 percent for the agriculture, hunting and forestry sector. For establishments with total employment of 20 and over, the response rate is 88.3 percent while that for establishments with total employment of less than 20 the response rate is 94.0 percent.
For the fishing sector, the total number of sample establishments is 689, that is, 156 for establishment with total employment of 20 and over, and 533 for establishment with total employment of less than 20.
The overall response rate is 97.5 percent for fishing sector. The response rate is 93.6 percent for establishments with total employment of 20 and over, and 98.7 percent for establishments with total employment of less than 20.
Sample weights (W) for the establishment data were computed as,
N = total number of establishments
n = total number of sample establishments
Weight Adjustment Factor for Non-response
To account for non-response in the non-certainty strata, the adjustment factors n/n' was multiplied with the weight (W) of each sampling unit. The sampling weight was recomputed as
W' = N/n * n/n' = N/n' General Formula
n' = total number of responding establishments in a stratum
For the agriculture, hunting and forestry sector, the weight of each sample establishment is N/n'. For the fishing sector, all establishments are taken as certainty samples, that is, the selection probability is 1 hence the weight of each sample is 1.
Refer to technical documents Section 'Estimation Procedure' of the Publication Volume for the complete details of weight adjustment factor for non-response.
Dates of collection
Mode of data collection
Self- administered questionnaire and face-to-face interview in some instances.
Data collection supervision
Supervision was done by Regional Directors, Provincial Statistics Officers, and regional and provincial statisticians while spotchecking was done by selected Industry and Trade Statistics staff (ITSD) with the assistance Provincial Statistics Officers/Statistical Coordination Officers to ensure the efficient conduct of the census operations.
Two rounds of spotchecking were conducted by selected ITSD staff in January to February 2008 and in April 2008 to further improve the response rate and quality of reports. Selected provinces were visited based on their response rates and number of uncollected questionnaires. Establishments with total employment of 100 and over were prioritized. During the spotchecking, the ITSD staff held meetings with field staff to discuss and assess the problems encountered in data collection. They also visited sample establishments found to be non-responding, closed and those with problems in the submitted 2006 CPBI questionnaires.
The 2006 CPBI utilized four types of questionnaires with NSCB approval numbers and expiration date of June 30, 2008. The questionnaires used were structured based on the 2000 CPBI Forms 1 and 2 questionnaires, and from the comments by the Technical Committee on Survey Design, NSCB Technical Staff and Technical Working Groups on Questionnaire Design and Processing Manual.
The 14 sectors of the economy were grouped into four namely: agriculture, industrial, construction, and business and services. Each group utilized only one questionnaire and were administered to all sample establishments regardless of employment size.
The agriculture group utilized CPBI Form No. 1 with NSCB approval NSO-7404-01, the questionnaire used for the agriculture, hunting and forestry sector, and fishing sector.
Refer to documentation for the copy of CPBI Form No. 1.
In addition, an e-questionnaire or electronic copy of forms for the 2006 CPBI was developed for respondents to submit via the NSO Website. The file of the e-questionnaire is in excel format and can be accessed using Microsoft Office Excel. Every page in the CPBI questionnaire has a corresponding worksheet in the e-questionnaire. The file has also a macro-program that enables the user to create an encrypted text file of the supplied data. The encrypted file is then emailed to NSO (ITSD-Receipt and Control Unit) for submission by respondents, thus facilitating data collection.

Manual editing of data was done in three levels, as follows:
· Field editing of data was done by the field men, hired SRs and provincial staff upon collection of the accomplished questionnaires from the sample establishments. The objective is to check for completeness and consistency of entries in the questionnaires, following the instructions provided in the Field Operations and Processing Manual. Any inconsistent or missing data was corrected at this stage as this can be immediately verified from the respondents.
· Office verification was done by provincial office staff upon receipt of the accomplished questionnaires from the field men and hired SRs. In some instances, the staff contacted directly the establishments through phone call or sent email inquiries to verify some inconsistent or missing data.
· Desk verification was done by the ITSD staff to check the consistency and reasonableness of entries in the accomplished questionnaires. Consolidated reports of enterprises were disaggregated at the firm level based on the reports submitted by the enterprise using ratios and proportions of individual firms tof enterprise. This process also validated the status of establishments that were non-responding and reported closed, cannot be located, transferred, and out of scope. Telephone inquiry was extensively utilized to verify information from the establishment's contact person. The internet was also used to obtain information on the contact address and to research for information on the status of the establishment.
Other forms of data appraisal
Indicators were derived to check for the consistency between data items and also compared with indicators of previous economic surveys and censuses. Growth rate of variables were also checked with data obtained from top 1000 corporations, as released by Securities and Exchange Commission.
