The HSES 2012 is a nationally representative survey, which aims to evaluate and monitor the income and expenditure of households, update the basket and weights for consumer price index, and offer inputs to the national accounts. The HSES is a survey regularly conducted by the NSO and covers a 12-month period for analysis.
Mongolia is divided into 21 aimags. Ulaanbaatar is the capital city and is subdivided into 9 districts, 121 khoroos and 1,035 khesegs. Each kheseg has approximately 200 households. The rest of the country is divided into soums and bags. One of the soums in each aimag is normatively considered as the aimag center, while the others are regarded as the rural area.

Coverage
The survey is nationally representative and covers the whole of Mongolia.
Households (defined as a group of persons who usually live and eat together)
- Household members (defined as members of the household who usually live in the household, which may include people who did not sleep in the household the previous night, but does not include visitors who slept in the household the previous night but do not usually live in the household)

Sampling
The 2011 HSES used the sampling frame which was developed by the NSO based on 2005 population figures obtained from local registration offices. This updated sampling frame was of great importance because the spatial distribution of the population had changed dramatically over the last years and any frame based on the Census 2000 would not be relevant anymore.
The design of the survey recognizes three explicit strata: Ulaanbaatar, aimag centers, and soum centers and the countryside. In addition, the sample was implicitly allocated by districts and khoroos in Ulaanbaatar, and by aimags in rural areas. Each aimag center was an explicit sub-stratum. The selection strategy was different in each stratum: a two-stage process in urban areas and a three-stage process in rural areas. In Ulaanbaatar, 360 khesegs were initially selected, from each of which 10 households were chosen. In aimag centers, 12 or 24 bags were initially selected, and then 10 households from each bag. In rural areas, first 52 soums, then 12 bags in each soum and finally 8 households in each bag were selected. All 1,248 primary sampling units or clusters (units, bags or soums) were selected with a probability proportional to their sizes and were randomly allocated into twelve months of survey fieldwork.
The use of this sampling procedure means that households living in different areas of the country have been selected with different probabilities. Therefore, in order to obtain representative statistics for each stratum and for the country as a whole, it was necessary to use sampling weights. The weight which was assigned to each household corresponds to the inverse of the selection probability and takes the sampling strategy into account.
The sample of 11,232 households was allocated as follows: 3,600 in Ulaanbaatar, 2,640 in aimag centers and 4,992 in rural areas and soum centers. However, the actual sample size used for this analysis is slightly smaller: 3,572 households in Ulaanbaatar; 2,639 in aimag centers; and 4,987 in rural areas and small towns. The difference is explained by 60 households, for which complete information was unavailable and were thus, excluded.

- face to face
The overall data quality is to be considered of good standard. On the one hand, the large amounts of information that the HSES collects from households imposed new demands on operational strategies and data management compared to the previous HIES.
Data processing
All procedures were streamlined and centralized, which is likely to have had a positive impact on the quality of the information. On the other hand, three different rounds of consistency checks were applied to the data: first during the data entry process, then during the compilation of the raw data files and finally during the preparation of this report. In all cases it was possible to compare these listings against the actual questionnaires filled out by the households (and at least during the first round of checks, some households were visited again) and the data were amended whenever a mistake was found.Databases for the HSES 2007/08 have been unified and data error checking was made (by using STATA program) in cooperation with working group.
