%description
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').
