The population and housing census 2011 was an EU-wide census in all EU member states. In Germany, the basis was a largely register-based method. In this paper, it is shown that communities with less than 10.000 inhabitants have significantly less relative losses in the number of inhabitants compared to communities with more than 10.000 inhabitants.
