Abstract

The domains for the Philippine Family Income and Expenditure Survey (FIES) are the regions. Design-unbiased estimation for the provinces (smaller areas) would necessitate an increase the sample size to about four times. Considering further that FIES is conducted semi-annually (at the end of reference semester), using the same sample households for the survey year and administered with a lengthy questionnaire, response burden and refusals increases along with problems with willingness of interviewers to complete the task for the entire survey duration. This problem is addressed by keeping the regions as survey domains but partially rotating the samples in the two rounds of data collection. This study then proposes a model-assisted estimation procedure in combining panel data and data from independent samples to generate annual estimates at the provincial level. Simulation studies indicate the advantages of model-assisted estimation procedure over design-unbiased method in generating estimates at the provincial level. Furthermore, sample size requirement using model-assisted approach is only about half of the required sample size for the design-unbiased method for reliable provincial level estimates.
