    abstract = {Provides fast and easy access to German census grid
      data from the 2011 and 2022 censuses
      <https://www.zensus2022.de/>, including a wide range of
      socio-economic indicators at multiple spatial resolutions (100m,
      1km, 10km). Enables efficient download, processing, and analysis
      of large census datasets covering population, households,
      families, dwellings, and buildings. Harmonized data structures
      allow direct comparison with the 2011 census, supporting temporal
      and spatial analyses.  Facilitates conversion of data into common
      formats for spatial analysis and mapping (terra, sf, ggplot2).},
