Thomas Rahlf: Documentation of Choroplet Maps for Germany, 1882-2017. HSR Trans 33 (2020) v01.
As part of the 2nd edition of Germany in Data, 21 interactive choropleth maps were created at the district level. A total of eight thematic areas (population density, births, social care, voter turnout, grievous bodily harm, employed persons in the manufacturing sector, unemployed, and denominations), for which statistics are available at district level for current years (2011-2017), were compared to seven statistics for the German Empire and to five for the Weimar Republic. For the presentations, existing map geometries of the Max Planck Institute for Demographic Research as well as of Daniel Ziblatt and Jeffrey C. Blossom were linked with data records that were created in the 1980s and 1990s. The datasets are based on extensive publication material from official statistics. In addition to the mapping, full names of all districts and their assignments to higher-level administrative units have been added. The jQuery plugin Mapael was used to create the maps.
