COSTAT
KOSTAT is the short form for the KOSIS community of municipal statistics . This community operates a collection of small-scale local community population data. Both the participating cities and third parties can use them for spatial analyzes. Depending on the type and scope of data usage, the latter have to make a financial contribution.
Members are the cities of Bielefeld , Bremen , Dortmund , Frankfurt am Main , Hanover , Nuremberg , Stuttgart (these are represented by their statistical offices) and the Federal Institute for Building, Urban and Spatial Research .
A supervisory position in a federal state is elected every two years.
The supervisory body chairs the community and represents it internally to the cities providing the data and externally to the data users and in the executive committee of the KOSIS association. The KOSIS association is a self-help institution of the German cities for the joint development and maintenance of standards and procedures for municipal statistical information management. Around 100 German municipalities with more than 35,000 inhabitants are participating in the project, including all large cities with more than 400,000 inhabitants.
Data collection
About 26 million people are statistically represented, which corresponds to a third of Germany's population. The data basis are the population registers. The data are updated annually and are comprehensively quality assured. A long-term time series has been built up since 1998/99.
The data include population figures for specified age groups, gender and nationality as well as the number of households in an inner-city breakdown. In addition to the data for a large part of the cities, there is also the regional classification system (street directory) in digital form.
The following features are available:
Residents at the place of the main residence
- all in all
- Female
- not German
- under 18 years
- 18 to under 30 years
- 30 to under 40 years
- 40 to under 50 years
- 50 to under 60 years
- 60 years and older
- Eligible population (main and secondary residence)
- Number of households or comparable size
Each data record is preceded by the spatial reference with the municipality code and the identification from the small-scale structure. Data are available for around 9,000 territorial units; on average, almost 3,000 people live in each territorial unit.
With the inner-city spatial observation of the Federal Institute for Building, Urban and Spatial Research (BBSR) and the European cooperation project Urban Audit, there are further small-scale municipal statistical data collections that differ in terms of the scope of characteristics and spatial layout and thus address different target groups.
