The sample for the Kyrgyzstan Multiple Indicator Cluster Survey was designed to provide representative estimates of MICS indicators at the national level, in urban and rural areas, as well as for eight regions: Batken, Jalalabad, Issyk Kul, Naryn, Osh, Talas, Chui regions, and Bishkek. The urban and rural areas of each region were used as strata, where the sample design was made in two stages.
The principal objective of the sample design was to provide current and reliable estimates on a set of indicators covering the four major areas of the World Fit for Children declaration, including promoting healthy lives; providing quality education; protecting against abuse, exploitation and violence; and combating HIV/AIDS. The population covered by the 2006 MICS is defined as the universe of all women aged 15-49 and all children aged under 5. A sample of households was selected and all women aged 15-49 identified as usual residents of these households were interviewed. In addition, the mother or the caretaker of all children aged under 5 who were usual residents of the household were also interviewed about the child.
Four hundred clusters, or Census-1999 Enumeration Areas (CEA), were selected with a probability proportional to the population size in the first stage. For rural areas, populated settlements were used as Primary Sampling Units (PSUs). For urban areas, internal territorial-administrative units were used as PSUs. For each enumeration area, a household listing was updated and used as a sample framework for the second selection stage. Later, households with an equal probability were
selected, according to the up-dated lists of addresses.
In defining the cluster size, a high rate of intra-cluster correlation of different indicators was taken into account. This required clusters of small size, as well as consideration of the effective use of interviewers’ time, requiring a minimization of movement from one settlement to another. As a compromise between data accuracy and the efficient use of limited time and funding, a cluster size was determined to consist of 13 households.
Thus, a total sample volume consisted of 5,200 households. Given that a sample is not self-weighting, and that sample size by strata is approximately equal, sample weights were used for reporting national level results.
The sampling procedures are more fully described in the sampling design document and the sampling appendix of the final report.
