Household Budget Survey is the oldest sample survey in Bulgaria. Its beginning was set 95 years ago - in March 1925, when the first survey of family income and expenditure was conducted.
The survey is annual and it is included in the National Statistical Programme 2020. In the survey take part 3 060 randomly chosen households divided in three sub-samples each containing 1 020 households. During the April - June period households from each sub-sample are consistently included in the Household Budget Survey. Each household participates in the survey four months during the 12-month period of the method of rotation sample.
The households keep a regular record in the Household Diary on incomes and expenditure during the current month, also they keep a record on irregular income and expenditure during the previous two months, when they did not directly participate in the survey.
Household Budget Survey is a main source for income, expenditure and consumption of the population in the country that is needed to develop different policies and measures in the social sphere. Such surveys are conducted in all countries of the European Union and in a number of countries around the world. Eurostat periodically uses the survey data for comparison between EU members.
