The data were obtained through Household Budget Survey, which has been conducted since 2003 according to international standards and recommendations of Eurostat, International Labour Organization (ILO) and UN, thus providing international data comparability. The survey collects the data on income and household consumption, i.e. the data on basic elements of individual consumption. Besides, the survey compiles also the data on some important living standard indicators (dwelling conditions, supply with durable consumer goods, etc.), as well as some basic data related to demographic, economic and social features of households.

In this survey, a two-stage stratified sample is applied, with enumeration districts as primary and households as secondary selection units. Every fifteen days, 370 households are interviewed, i.e. 8856 households annually.

Of the total number of households envisaged for interview in the third quarter (2214 for the Republic of Serbia), the number of 1562 households (71%) was interviewed.
