Abstract

In March and September 2003, the Philippine National Statistics Office conducted the 2002 Census of Agriculture (CA) and the 2002 Census of Fisheries (CF), respectively. Given the constraints in the budget, manpower and other resources, the two censuses will be carried out through sample enumeration. However, in a sample enumeration, the major consideration is the availability of a reliable sampling frame to be used for the selection of samples. Other issues are the appropriate sampling design for the two censuses and the level of disaggregation at which the data will be available. The project was undertaken to address the issues cited above. Its objective is to evaluate all possible sources of information for the construction of the frame including the Barangay Screening Survey (BSS) of the Bureau of Agricultural Statistics (BAS). The construction of the sampling frame for the CAF 2002 necessitated the inventory of possible sources of information and different sampling options were considered. Validation of the BSS yielded a result that made it difficult to be a source of sampling frame for the CA. Hence, the CA used the total farm area from the 1991 Census of Agriculture and Fisheries and information from the 2000 Census of Population and Housing. All barangays in a municipality except in the National Capital Region were grouped into three (3) strata. In each sampled barangay, all households will be covered. While for CF, a barangay is classified either in stratum 1, 2, 3, 4, or 5 depending on the presence of fishing households in the barangay.
