Design of Sampling Frame and Sampling Method (Survey of Trade and Service Businesses)

Survey of Trade and Service Business: This is a sample survey with sample sizes determined to be sufficient for presenting survey results at the regional level, namely: Bangkok, Metropolitan Area (Samut Prakan, Nonthaburi, Pathum Thani, Nakhon Pathom, and Samut Sakhon), Central Region (excluding Bangkok and the Metropolitan Area), Northern Region, Northeastern Region, and Southern Region. Results are classified by all types of economic activities according to the Thailand Industrial Classification (TSIC-2009) at the activity level (5-digit TSIC), comprising 309 activity types. For establishment size, measured by the number of employees, Bangkok, the Metropolitan Area, and the four regions are defined as strata, totaling 6 strata. Within each stratum, establishments are divided into sub-strata based on establishment size and type of economic activity. This survey uses a Stratified Systematic Sampling design with establishments as sampling units. The sampling frame is the list of establishments nationwide obtained from the 2017 Industrial Census. To ensure the sampling frame is current, data is updated in the Sampling Frame Database Management System and the Sampling System (System 3) by the Bureau/Provincial Statistical Offices. In each sub-stratum of each region, sample establishments are selected using systematic sampling.
