The sample for 2019 Turkey ES was selected using stratified random sampling, following the methodology explained in the Sampling Note.
Three levels of stratification were used in this country: industry, establishment size, and region.
Industry stratification was designed in the way that follows: the universe was stratified into six manufacturing industries and three services industries. Food and Beverages (ISIC Rev. 4.0 codes 10, 11), Textiles (ISIC 13), Garment (ISIC 14), Fabricated Metal Products (ISIC 25), Machinery and Equipment (ISIC 28), Other Manufacturing (ISIC 12, 15-24,26, 27, 29-33), Construction (ISIC 41-43), Retail (ISIC 47, 95) and Other Services (ISIC 45, 46, 49-53, 55, 56, 58, 61, 62, 79, and 95).
As it is standard for the ES, the Turkey ES was based on the following size stratification: small (5 to 19 employees), medium (20 to 99 employees), and large (100 or more employees).
