Sampling
Sampling Procedure
Sample design
The Child development survey is a household-based survey. Therefore households are defined as the sampling units. The sample for the survey was designed to provide estimates for a large number of indicators on the situation of children, women and men at the aimag (province) level. The total sample size was determined as 2,000 households and it was variably allocated for each of the soums depending on the respective number of households.
The lowest administrative units (bagh of soum's in the aimag) were defined as primary sampling units (PSUs). In total for the Khuvsgul aimag, 80 PSUs were selected systematically with probability proportional to size. After a household listing of the selected PSUs was carried out by the soum's state treasury representative and the bagh governor, 25 households were selected using systematic random sampling in each PSU.
During the data collection fieldwork in August-September 2012, we had encountered a problem due to nonappearance of families at the registered addresses, and absence of family members, because of seasonal movement for livestock hay and fodder preparation, as well as during the vacation period. In spite of this, we managed to collect survey data from the selected baghs.
Data were collected from the households in the sample, and for reporting aimag level results, sample weights are used.
