It aims to update consumption weights for the Consumer Price Index baskets and estimate private consumption expenditure for the national accounts (GDP).  Before HSES, Household Income and Expenditure Survey (HIES) was a main survey and then since 2007, instead of HIES, HSES has been implemented in the current form. \nThe data is collected over 12 months and the main comprehensive form of the survey for poverty estimation has been implemented biennially since 2012. A short-form survey is conducted once every two years when the main comprehensive survey is not conducted. As for the data collection method, HSES has adapted computer-assisted personal interviewing (CAPI) method since 2014.\n\nSurvey questionnaire\n\nThe 2015 HSES was conducted in the comprehensive form, consisting of two sub-questionnaires with 11 modules in total.  These include:  \n\u00b7\tHousehold socio-economic questionnaire (HSES-1): The questionnaire HSES-1 aims to collect general information about the household characteristics, employment, livestock breeding and crop farming, non-agricultural manufacturing, trade, services, dwelling and energy, durable goods, and non-food expenditure data.\n\u00b7\tHousehold food consumption questionnaire (HSES-2a, HSES-2b): A combination of both a household diary and a recall methods are used to measure food consumption in the HSES survey. A thirty day diary (HSES-2a) compiled by an enumerator every 10 days, for three times during a single month is used to capture food consumption of hosueholds in Ulaanbataar and Aimag centers. A 7 day recall period questionnaire (HSES-2b) is used to capture food consumption in Soum Centers and the countryside.","coll_dates":[{"start":"2015-01-01","end":"2015-12-01","cycle":""}],"nation":[{"name":"Mongolia","abbreviation":"MNG"}],"geog_coverage":"The survey is nationally representative and covers the whole of Mongolia.","universe":"Households (defined as a group of persons who usually live and eat together)\n- 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)"},"method":{"data_collection":{"sampling_procedure":"Sampling\n\nThe HSES is representative of the nation, region, urban\/rural areas, residential location and amigas. It was enumerated in 320 soums and 9 districts of Mongolia. In total 11,232 households were randomly selected for the HSES 2015.\n\nSampling frame\nThe list of all households of Mongolia or the list of households registered in the population and households' database at NSO was used for HSES as a sampling frame. \n\nSample size\n\nFor the HSES 2015, the sample size is 11,232 households, of which 936 households were surveyed each month.\n\nSamling design\nThe HSES's sampling strata or geographic domains of estimation were decided to the level of four residential location zones: Ulaanbaatar, Aimag center, Soum center, and Countryside.\nHouseholds were selected using two stages of probability sampling. In the first stage, Primary Sampling Unit (PSU) was selected, using probability proportional to estimated size, and then in the second stage, households are selected in the selected PSUs using simple random sampling.\n\nIn the HSES, Primary sampling units (PSUs) are kheseg in Ulaanbaatar, and bag in aimag, soum centers and countryside.\nIn Ulaanbaatar city: \n-\t360 PSUs were selected out of total khesegs of UB city  \n-\t10 households were selected from each selected khesegs. \nIn aimag centers: \n-\t12 PSUs were selected from each aimag center. Taking into account the number of households, 24 PSUs from Darkhan-Uul aimag and Orkhon aimag. \n-\t10 households were selected from each PSUs. \nIn soum centers and countryside:\n-\t24 bags were selected from each aimag as PSUs. For Khentii, Selenge, Bayankhongor, Zawkhan, Bayarn-Ulgii and Uvs aimags, 36 bags were selected. For Uvurkhangai, Tuv and Arkhangai aimags, 48 bags were selected. For Khuvsgul and Darkhan aimags, 60 and 12 bags were selected, respectively.\n-\t8 households were selected from each PSUs. \n\nSampling distribution\nThe sample size is distributed using proportional probability sampling techniques. Sampling distribution is made to be proportional to each domain, taking into account the number of households of aimags.\n\nThe sampling weight applied for each sample household is equal to the inverse of its probability of selection. \n\nIn the 2015 HSES, 99.8 percent of the selected hosueholds, or 11212 households have participated in the survey.","sources":[{"name":"","origin":"","characteristics":""}],"coll_situation":"The overall data quality is to be considered of good standard.
