FDZ Data description: Population projection for Germany 2015–2050 on grid level (RWI-GEO-GRID-POP-Forecast)

RWI Datenbeschreibung

Existing nationwide population projections focus on highly aggregated spatial units. The most regionalized nationwide study is provided by the German Federal Institute for Building, Urban Affairs and Spatial Research (BBSR) and predicts population on county level up to 2035 (BBSR 2015). Projections of the German Federal Statistical Office – marking the benchmark approach for German population projections – are constraint to agglomerated projections for entire Germany or for federal states, provided by the state offices. Existing small scaled data e.g. the RWI-GEO-GRID impressively reveal the high heterogeneity of local socioeconomic traits within commonly applied county- or municipality-data. Based on these existing population data on the grid level (offering a resolution of 1×1km-grids), the presented RWI-GEO-GRID-POP-Forecast provides a population projection up to 2050. The applied methodological concept strongly follows the approach of the German Federal Statistical Office and the agglomerated results are in line with this projection. This article gives an overview on the provided dataset, the applied methods, some basic results and the access to the data for scientific purposes.
