The microcensus is conducted every year and usually starts in January, and can be contacted throughout the year. There are three ways to do this: telephone, online or paper questionnaires. On-site visits are also possible in principle, but only in exceptional cases due to the pandemic.
The collected data is relevant, for example, for adjustments to parental or housing benefits or pensions. The results also flow into the poverty and wealth reports of the federal government and the federal states as well as into the children and youth report of the federal government.
Every four years, the microcensus asks in-depth questions on the subject of housing, and this will also be the case in 2022. The data from this additional program provides information about the home ownership rate or the average rent burden of households in Germany, for example.
Across Germany, more than 30,000 households are written to for the microcensus each month by the competent state statistical office. Anyone who has been selected is legally obliged to provide information. In order to be able to make statements about changes and developments in the population, the selected households are usually surveyed up to four times (maximum twice within a year).
