Household Budget Survey

The Household Budget Survey describes in detail the Danish households' expenditure on goods and services and the economic condition of the households. The statistics are used to compile weightings in the Consumer Price Index and for calculation of the private consumption in the National Accounts. The statistics were first compiled in 1897 and annually since 1994.

Statistical presentation

The Household budget survey is yearly calculated at Households level. The survey is based on a combination of interviews, accounting and administrative data from the participating households. 99 per cent of the total population is covered by the survey, which covers all private households in Denmark.

Statistical processing

The survey is based on a sample where the number of households accounts for about 2,200 out of Denmark's total of approximately 2.6 million households.

The survey included data from three different data sources: Accounting booklets, CAPI interviews and data from registers. In this way the sample can give results which are good approximations for all private households. The data from the 3 different sources are validated. We are constantly looking at how we can improve and compile the statistic in a more efficient way.

The data is collected annually from approximately 1,100 households. Such a sample is too small to form the basis of very detailed statistics and therefore we averaged data from two consecutive years to a single sample. All expenses, income, etc. are converted to the price and volume level of the end year.

Consumption survey is published annually. Preliminary figures 20 months. After the reference year, while the final figures are published 27 months. After the reference year.

Relevance

Public authorities' planning and feasibility studies, etc. Internationally, where especially EUROSTAT is very active in order to establish comparable figures between countries. Research in a number of areas, as well as for marketing purposes.

Accuracy and reliability

With only 19 pct. of the households who have been contacted participating in the Household Budget Survey. This creates uncertainty, not least for detailed consumer groups. For total consumption, this means that there is an uncertainty margin of +/- 1.2 per cent. while that for that for bread is 1.9 per cent. and 58 per cent. for a rarely purchased item such as condensed milk. There is underreporting in a number of areas such as alcohol, tobacco, prostitution and undeclared work. The uncertainty is greater when data is based on accounting rather than interviews, and it will be greater if one looks at smaller subgroups of households.

Timeliness and punctuality

The statistics are usually published according to the time announced. The statistics are published annually 12 months after the end of the year.

Comparability

The Household Budget Survey is conducted in accordance with guidelines from the European statistical agency Eurostat. Comparable figures are published by Eurostat. Since 1994, the survey has been methodologically rearranged and is now conducted annually by the same method and on a comparable basis.

Data for 2014 and onwards are based on a two-year-old sample and COICOP5 nomenclature. To ensure comparability and continuity over time, data from 1994 to 2013 were recalculated in compliance with the new nomenclature in both current and constant prices
