Design of sampling frame and sampling method (Labour Force Survey)

The Labour Force Survey (LFS) is a sample survey conducted annually in four rounds (four quarters), with fieldwork distributed monthly to ensure sufficient data for quarterly survey result presentation. The sample size is determined to be sufficient for presenting survey results at the provincial level (without administrative district breakdown). At the regional and national levels, survey results are presented with an administrative district breakdown, i.e., within municipal areas and outside municipal areas. The National Statistical Office has applied the Rotation Sampling method to improve estimator quality in the LFS, which was used from 2545 - 2554 and 2555 – 2564. The current rotation plan is used from 2565 - 2574. The current rotation sampling plan divides sample Enumeration Areas (EAs) into 10 sets (EA sets) for the LFS. Each year, the LFS is designated to use 2 sets of sample EAs, or 2 EA sets. In each sample EA, 10 sets of household and individual samples are designated to be selected, namely sets A, B, C, D, E, F, G, H, I, and J. The LFS uses 4 sets of household samples, namely A, B, C, and D. This survey is designated to use a Stratified Two-Stage Sampling plan, with Enumeration Areas (EAs) as the first-stage sampling units, and households, individuals, and members of worker household groups as the second-stage sampling units. The first-stage sampling frame is designated to use the Enumeration Area (EA) list recorded in the 2553 Population and Housing Census, with data updated annually through household listing from the Basic Household Data Survey (BHDS) for sampling unit selection.
