Varona2 and Josephine O. Tabernilla3 Abstract to produce reliable labor force estimates at the province level. This sampling design also served as prototype or model For several years now, the for the development of the new master Philippine Statistics Authority (PSA) is sample for household-based surveys. working continuously to develop and improve the master sample design and to This paper aims to illustrate the enhance the sampling frame of PSA’s experience in the development of household-based surveys, such as, the sampling frame for the two pilot Labor Force Survey (LFS), Family provinces. The sampling frame Income and Expenditure Survey (FIES), development involved the formation of Annual Poverty Indicators Survey (APIS), primary sampling units (PSUs) with about Survey on Overseas Filipinos (SOF), similar sizes ranging from 100 to 400 Functional Literacy, Education and Mass households. The sampling design was Media Survey (FLEMMS), etc. based on Probability Proportional to Size (PPS) which consider the number of The PSA is currently using the households as the measure of size. The 2003 master sample (MS) design to cater information on the number of households several household-based surveys. The was obtained from the results of 2010 2003 MS design can only provide reliable CPH. To give more emphasis on the estimates at the regional level. With the reduction of non-sampling error, clearer availability of data from the results of the and more precise PSU boundaries would 2010 Census of Population and Housing be necessary. The use of available (CPH), the plan to develop a 2010 CPH- satellite imagery in constructing based master sample that will provide segment/PSU boundaries was reliable province level estimates had recommended not only for the pilot been pursued and started. provinces but for other provinces as well. Using digitized satellite maps (i.e, Google Recently, the PSA in collaboration Earth digitized maps) together with the with the International Labor Organization 2010 CPH listing forms and available (ILO) Manila carried out a pilot survey for sketch census maps (i.e., 2010 CPH the labor force that will produce reliable enumeration area (EA) maps and block estimates at the provincial level. Two (2) maps for congested areas), the pilot provinces, Antique and Agusan del determination of appropriate Sur, were identified as the pilot survey segment/PSU boundaries were relatively domains to carry out this project.
