EconStor: Geburtsstaat und Geburtsort im Ausländerzentralregister ... econstor.eu › handle › 10419 › 253431
Official statistics use the variables 'country of birth' and 'place of birth' from the Central Register of Foreigners. In the administrative context, however, the variables are collected incompletely (country of birth) or unstructured as free text (place of birth) and without plausibility checks. The Federal Statistical Office develops concepts for the standardisation, validation and supplementation of administrative data, so that these can be used for statistical purposes. The article focuses on the processing of the country of birth data from the Central Register of Foreigners for reference day 31 December 2020 and on first exemplary analyses based on that. Also, a concept for the potential processing and geocoding of the place of birth data is presented.
