The HSES is a nationally representative survey that aims to estimate and monitor the level of poverty of the country and people's living standards. 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.
The 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.
