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

Informal Labour Force Survey. This is a sample survey conducted in the third quarter (July - September) every year, with work distributed by month. It uses the same Enumeration Area (EA) sample size and household sample size as the Household Economic and Social Survey (HESS). 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, specifically within and outside municipal areas. This survey specifies the use of Stratified Two-Stage Sampling, with Enumeration Areas (EA) as the first-stage sampling unit, and households, individuals, and members of group households of the worker type as the second-stage sampling unit. The first-stage sampling frame specifies the use of the EA list recorded in the 2553 Population and Housing Census, with data updated annually from the household listing of the Household Basic Data Survey (HBDS). For the selection of first-stage sampling units, EA samples are selected independently in each province based on administrative districts, with the probability of selection being inversely proportional to the number of households in each EA. The second-stage sampling frame specifies the use of the list of individual households and group households of the worker type obtained from the HBDS listing. For the selection of second-stage sampling units, individual household samples are selected using systematic sampling. In the case of group households of the worker type, this stage involves selecting sample members residing in all group households of the worker type in each EA.
