- Additional information (2020-2021):German microcensus final results – population in families/living arrangements in private main residence households. Impact of the methodological redesign and the Covid-19 crisis on the microcensus 2020 and 2021 results:A completely new IT system was set up for the redesigned microcensus from 2020; its introduction was accompanied by technical problems. Individual technical challenges continued in the 2021 survey year. Together with the partially ongoing effects of the corona pandemic, these led to restrictions in the survey conduct. Taken together, however, the effects were much less strong than in 2020 - analysis limitations may still occur in deep technical or regional breakdowns. The average non-response rate for the final results of the 2021 microcensus is approximately 14% at the federal level (first results approx. 17%). This value is considerably lower than in 2020 (approx. 38%; final result approx. 35%). Thus, there is an improvement in the quality of the annual results in 2021 compared to 2020.

- 2011-2021: The statistics are based on register-based household statistics, which are based, in turn, on population registration by dwelling unit and an imputation model for people who are not registered in a dwelling. Households with a single parent are based on households that have been classified as single parents with children. Couple households are based on households that have been classified as households with cohabiting adults. There are persons who have been defined as single parents or cohabiting couples in households that have been classified as Other households. These “families” are included in other households.
- Information on three-generation households has only been calculated from 2011 and forward. These refer to households that consist of persons from three generations, which, in practice, can be a grandparent that belongs to the same household as a grandchild. Therefore, in a few cases there may be multi-generational households among single-person and cohabiting adult households. However, in this table, only multi-generational households in the other households group have been calculated.
Children are defined based on relationships. In addition to biological and adopted children, children are linked together based on the pregnancy of the guardian and “Other person”. This means that an older sibling may, in some cases, be classified as a parent to their younger sibling. There is no age limit for children.
- Prior to 2011, the statistics were based on sample surveys.
