Sampling
Sampling Procedure
The sample for the Social Indicator Sample Survey was designed to provide estimates for a large number of indicators on the situation of children, women and men in Nalaikh district, and its seven khoroos (first to seventh khoroos).
Deviations from Sample Design
A total of 1000 households were selected and selection probabilities and corresponding weights vary by soum and PSU. As the main sampling strata, the sample was selected in two stages. At the first stage the primary sampling units (PSUs) within each stratum were selected systematically with probability proportional to size (PPS). After a household listing was carried out in the sample PSUs, a systematic sample of 25 households was selected within each sample PSU in second stage.
The official statistics of the household registration end of 2015 was used as a sampling frame. As the lowest administrative units - 52 khesegs of 7th khoroos were defined as primary sampling units (PSUs).The listing of households was updated during September to October, 2016.
Thus the data collection fieldwork took place during November and December 2016, when the internal migration of households was stable and managed to collect survey data entirely and covered all 52 selected sampling units.
