Mongolia - LFS 2006/2007

The sampling unit of survey is a household. The sample frame of 2006-2007 has been the administration units of Mongolia and the sampling was based on 2005 household, population and work age population to improve the previous sampling design. As of 2000 Population and Housing Census, the total population amounted to 2,373,493 and household to 541,149 whereas these figures went up to 2,594,792 and 632,500 respectively by the end of 2006. In addition, the migration was on the rise. Therefore, it was necessary to redesign the sample based on the final data of the previous year. As most of enumeration areas of 2000 Population and Housing Census disappeared or significanly reduced in size, the survey had to make sampling by aimag, soum and bag frames. At the same time the sampling technique required to split some of primary sampling unit (bags in aimag centers and parts of the cities which had a large number of residents) into smaller segments. In light of this requirement and ratio between sampling units and sample households, the number of households in sample enumeration areas was set at 12 and enumeration areas at 1024.
A total of 29 strata was made comprised of 21 strata representing each of all aimags and 8 strata from 9 districts of Ulaanbaatar city(least populated two districts were put into one strata). Primary sampling units are parts of khoroos of Ulaanbaatar city and bags in aimags to make up 1024 units in total comprised of 384 parts and 640 bags. The second labour force survey adopted a multi stage stratified sampling design. Sampling was made on estimate of the weight of unemployment in total population. In addition, sampling distibution by aimag anc city districts was made in proportion to work age population. At primary sampling stage, the selection was made by probability proportional to size and at secondary stage 12 households were selected from each enumeration area using the simple random sampling procedure. To rephrase, the survey households were chosen with the method of a sub-sampling.
