Statement

For a few individual grid cells, the values shown may appear implausible. This is due to the fact that a back calculation of the census data had to be performed, based on data from demographic statistics. As this data is given at municipality level (LAU3) and not at grid level, a mapping between grid cells and municipalities had to be created in order to maintain the municipality figures correctly. In individual cases, it is therefore possible that the population of a small municipality is partially assigned to the wrong grid cell in order to obtain exact figures at a higher aggregation level. Please note that floating point values may result from the back calculation. For reasons of plausibility, these have been rounded, what might result in minor deviations and non-additivity. Notably the sum of all grid cell values deviates from the total population.To implement the EU-wide census, Germany opted for a register-based method instead of the full census used before 2011 census.<br /><br />Use of register data:<br />In Germany, the requirement to register means that all local authorities have population registers available containing comparable information.<br />However, this administrative information contains no data on employment, education, profession or housing. Information on the economic activity of certain groups (such as the self-employed) can also not be found in registers. There is no comprehensive register information on buildings and dwellings in Germany.<br /><br />Supplementary surveys:<br />The building and dwelling census was carried out as a full census:<br />Around 23 million owners or administrators of houses and apartments were sent a postal survey.<br />The household survey was conducted on a sampling basis:<br />Around 10.5 mio persons were covered by the household survey. The respondents were selected using a statistical mathematic random procedure. Initially, addresses were selected at random. Subsequently, all the individuals living at these addresses on 15May 2022 were interviewed.<br /><br />Following the survey, this information was then extrapolated for the entire population, thus providing reliable data for both the municipalities and the whole of Germany.<br />At 4 % of the addresses where the household survey was carried out, the occupants were surveyed a second time several weeks after the first interview. This repeat survey was carried out by different interviewers using a questionnaire shortened to only a few characteristics.<br /><br />The survey in residential homes and other forms of collective accommodation was carried out as a full census:<br />The 2001 census test and the 1987 population census showed that the population registers are particularly inaccurate for residential homes and other forms of collective accommodation. Therefore, in order to reliably determine the population of municipalities and urban districts, in the 2021 census data were collected on all residents of residential homes and other forms of collective accommodation. This information was used to correct the data from population registers on the reference date.<br /><br />Household generation:<br />Household relationships were formed from the individual parts of the survey in a separate procedure known as household generation. This was done using information taken directly from the registers and from the analysis of the dwelling occupant data.Part of survey: household survey (sample survey)<br />A repeat survey was carried out to assess the quality of the sampling results as regards the official population figures . To this end, 4 % of the addresses selected during the household sample were surveyed again.<br />A shorter version of the questionnaire for the household sample was used. The primary statistical survey was also carried out by interviewers.<br /><br />Part of survey: housing census (full census)<br />The non-response rate was in line with expectations. It was not possible to collect data from respondents for around 8 % of all buildings. In these cases the data had to be imputed or, if this was not possible, the property was visited by a municipal interviewer.There is no evidence for general unreliability of the data on the topics being part of the grid cell dataThe 2021 German census micro data are covered by statistical confidentiality pursuant to § 16 of the Bundesstatistikgesetz [Federal Law on Statistics]. It must therefore be ensured that it is not possible to identify individual information on person and factual circumstances from the published tables.A rounding procedure was applied to small population numbers.
