What data does the census provide?
It's already been a few days since the latest census data was published. But you could say that the topic will remain "topical" for the next 10 years.
Due to EU census regulations, Germany is obliged to carry out a census every 10 years. The last census took place in May 2011, but for those who remember, coronavirus intervened. By law, the census was postponed by one year due to the pandemic. The 2011 census was the first census since the 1987 (FRG) and 1981 (GDR) censuses. This time it was "only" a period of 11 years.
The census (population census, which is used to obtain population and housing data ) is a joint task of the federal and state statistical offices. It is a register-based population census. It is supplemented by a sample and combined with a building and housing census.
Significance for the Nexiga database
The census data is an important tool for Nexiga for validating, optimizing and expanding the market database. Data on building age, heating type, energy source and construction method are just as important for optimizing the Nexiga house database as the ownership structure and average net cold rents(real estate data).
In addition to validating and updating our features at regional level with the socio-demographic results of the census, our Building and building database benefits from the results of the building and housing census. One example of this is the fine-grained data for heating types and energy sources, which we can evaluate and process down to house level using specially created references. This enables us to optimize and supplement our information on gas network availability and the use of alternative energy sources such as heat pumps for the energy market, for example.
However, we do not accept the results without checking them, but always take the plausibility and topicality aspects into consideration. The information basis may be more up-to-date in certain areas. In addition, there are cases in which municipalities arrive at different results than the data published in the census.

Optimization

Supplement
Results of the building and housing census provide new detailed data, e.g. on heating types and energy sources. -
Plausibility & up-to-dateness
The results of the census are not transferred to the Nexiga database without being checked. Nexiga's own information basis, validated by other data sources, may be more up-to-date.
Current census results 2022
Germany's population has grown less strongly in recent years than previously assumed. This is according to the results of the 2022 census. According to the results, there were around 82.7 million people living in Germany on May 15, 2022, around 1.4 million fewer inhabitants than previously assumed on the basis of the official population update.
The census determines the population figures of all 10,786 municipalities in Germany. In 56 percent of these municipalities, there were at least one percent fewer people on May 15, 2022. According to the data, the deviation was particularly large for Cologne, where 5.6 percent fewer people lived on the cut-off date than assumed.
According to the data, the nationwide deviations from the population update particularly affect the foreign population. According to the 2022 census, there were around 10.9 million foreigners living in Germany on May 15, 2022, almost one million fewer than previously officially reported. One reason for this is that some foreigners have not deregistered in Germany, for example if they are spending their retirement abroad.
The majority of the population does not have to provide information for this type of census. Detailed background information on the implementation of the census can be found on the website of the statistical offices. To the official website

A look back at 2011
The last census in Germany was carried out in 2011. The most important finding was that Germany had significantly fewer inhabitants than previously assumed. On the cut-off date, there were 80.2 million people living in our country - 1.5 million fewer than assumed. This corresponds to a city larger than Munich. The figures at the time were based on the 1987 (FRG) and 1981 (GDR) censuses. Since then, the population figures have been continuously updated with the help of data on births, deaths and changes of registration.
In 2011, the census results caused great excitement in the municipalities, as the population figures for many towns were significantly lower than the previous official statistics. This also meant significant financial losses, particularly in terms of municipal financial equalization. There were many complaints from municipalities to the administrative courts.
