In 2022, one will once again determine how many people live in Germany, how they live and where they work. This collection of statistics is called census. Many decisions made at national, federal or municipality level are based on population and property figures. A regular review of the population size is necessary in order to have reliable baseline figures to plan with. The data primarily stems from administration registries, so that the majority of the population does not have to provide any information.
In the concepts of the 2022 census, refugees are also considered. For this reason, it might be the case that you will be questioned in the 2022 census if you stay in Germany in the longer term. Please, find further information on the 2022 census here: https://www.zensus2022.de/
