Replication package for: Mapping access to medical service provision at micro-scale: Dynamics in supply and demand in Germany

EN: This dataset includes a 100 m raster of changes in access to primary care physicians in Germany. It complements the article "Mapping access to medical service provision at micro-scale: Dynamics in supply and demand in Germany".

For calculating the change in access, data on physicians and population for the years 2011 and 2022 on the level of individual buildings has been combined using the Enhanced Two Step Floating Catchment Area (E2SFCA) method and aggregated into the provided 100 m raster. A maximum travel time of 20 min by car was assumed.

Physician data consisted of full-time-equivalent (FTE) values for precise physician locations, provided by the "Kassenärztliche Bundesvereinigung". Population for 2011 was taken from the official census and dasymetrically mapped to building footprints, while the data for 2022 has been estimated on building level using an AI-based approach. The calculation of the catchment areas was conducted with "OpenRouteService". The aggregation raster is the official INSPIRE 100 m.

The results for the access calculation are presented in a unit we call "Minutes", which can be understood as the theoretical maximum amount of time any person can spend at primary care physicians in a year. The higher the value, the better the access to service provision.
