Mass data-based long-term models of migration-induced growing diversity in an urban context: Foreigner registration files as cultural assets and the basis for reflexive migration research

The project is based on the digitisation of Osnabrück's analogue foreigner registration file ("Ausländermeldekartei") for the period from 1930 to 1981. AI-based data extraction and GIS-supported modelling enable the tracking of migrants' movements within the city and the analysis of segregation and integration processes, thereby observing the migration-induced social change of an urban society. Furthermore, it is possible to reveal practices of administrative knowledge production about migration in the datafied foreign residents' register.
