Using geographic information systems (GIS), we mapped housing and population counts from the decennial U.S. Census Data at block group level geography to produce a spatially explicit dataset for the coterminous U.S. We also overlaid the raw housing data with the Protected Areas Dataset (PAD version 1.1) to split census block groups into privately and publicly owned sub-blocks, thereby creating a map that more accurately locates where people and houses exist in space. This data is useful within a GIS for mapping and analysis at national, state, and local levels.
