Sampling
Sampling Procedure
The survey was designed to interview a representative national sample of about 12800 households from Ulaanbaatar and urban and rural areas of 4 regions that was deemed sufficient to collect reliable data on employment and unemployment and child labour. The child labour surveys target group was 5-17 years old population. At this level of disaggregation the sample would be sufficient to produce estimates of high levels of precision in respect of selected child work and labour characteristics. The desired ratio between survey sampling units and households, the survey unit was set up as 12 households and units as 1068. These more detailed sampling techniques enabled to produce estimates of working children by aimags, which was one of main advantages of this survey over the previous survey.
