Study notes
The 2006 Census of Philippine Business and Industry (CPBI) is a comprehensive collection, compilation, evaluation, analysis and dissemination of data about the economic activities of a country. It seeks to collect and generate information on the levels, structure, and trends of economic activities in the entire country. It also serves as a benchmark for the measurement and comparison of national, regional and provincial economic growth.
The scope of the census consists of 14 sectors of the Philippine economy as classified in the 1994 Philippine Standard Industrial Classification (PSIC).
This metadata presents the documentation of three sectors only namely: Mining and Quarrying sector (Major Division C), Manufacturing sector (Major Division D) and Electricity, Gas and Water Supply sector (Major Division E). It includes the procedures undertaken in all phases of the census, information on the final datasets, publication volumes, copy of questionnaire used, and other informative documents related to the census operation.

Sampling
Sampling procedure
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 complete details of the aboved-mentioned procedures are in 'Sampling Design' section of publications (Volumes III to V) included in the Reports linked to this documentation.
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 and other establishment-based surveys such as MISSI and QSPBI. 'Hot and cold deck' imputation methods were used for partial and total non-response.
The 2006 CPBI sampling frame is extracted from the 2006 List of Establishments (LE). The 2006 LE is the combined result of the following:
1. 2004 Updating of the List of Establishments conducted in the NCR and in selected urban barangays in cities, provincial capitals and first class municipalities (2004 ULE areas) during the period September 2004 to May 2005
2. 2005 ULE in rural barangays in provincial capitals, cities and municipalities of selected provinces conducted from September to December 2005. The selected provinces are the provinces in Regions 3, IVA and IVB, provinces where the NSO Regional Office is located, and provinces with the highest count of establishments in rural barangays of provincial capitals, cities and municipalities. It also covered growth areas in selected provinces
3. Supplemental lists containing establishments in the following sources but not found in the LE
. Bureau of Fisheries and Aquatic Resources list of fishing companies
. Bureau of Internal Revenue business taxpayers (corporations only) as of 2004
. Clark Special Economic Zone 2006 list of locators
. Department of Education list of schools
. Department of Tourism list of hotels
- Federation of Philippine Industries list of members as of 2006
- Frame of the 2006 Survey of IT-Enabled Services of Bangko Sentral ng Pilipinas
- Laguna Lake Development Authority list of fishpen operators (corporations only)
- Philippine Export Zone Authority list of firms as of June 30, 2006
- Philippine Retailers Association list of members as of July 2006
- Subic Bay Freeport Zone and Subic Economic Zone approved projects as of August 31, 2006
· Survey feedbacks from the 2006 Monthly Integrated Survey of Selected Industries (MISSI), 2006 Quarterly Survey of Philippine Business and Industry (QSPBI), and the 2005 ASPBI
· List of Establishments with total employment of 20 and over verified existing by field offices.
An estimate from the 2006 LE shows that there were about 783,000 establishments in operation in the country for the year. Distribution of these establishments, as shown in Figure 1, reveals that about 80 percent are classified in the informal sector and thus are excluded from the 2006 CPBI frame.

Weighting
Sample weights (W) for the establishment data were computed as,
W=N/n
where:
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 which is defined as W=N/n was recomputed as
W' = N/n * n/n' = N/n' General Formula
Please refer to the complete details of weight adjustment factor for non-response in the 'Estimation Procedure' section of the publications (Volumes III to V) included in the Reports linked to this documentation.

Data collection supervision
The NSO has an organizational structure in the field offices that undertakes the data collection for all censuses and surveys. Regional Directors, Provincial Statistics Officers, and Regional and Provincial Statisticians served as supervisors 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 increase the response rate and improve the 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.

Data Processing
Data editing
Manual editing of data was done in three levels, as follows:
a) Field editing of data was done by the field men, hired SRs and provincial staff upon collection of the accomplished questionnaires from the 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.
b) 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.
c) Desk verification was done in the Central Office to check the consistency and reasonableness of entries in the accomplished questionnaires. 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.
