Dual Graphs for 2010 Census Units

County Subunit
Block Group

This page contains links to five dual graphs for each state, corresponding to the Blocks, Block Groups, Tracts, County Subunits, and Counties as defined by the census in 2010. Each graph contains adjacency information, geographic measurements, as well as population values and Urban/Rural labelling. Full descriptions of the tabular data are here.

The underlying geographic data was downloaded from the census website and processed using GerryChain and maup. Each node in the graph represents one unit and there is an edge between two units if they share a positive length boundary. Population values are aggregated up from census blocks and geographic measurements are taken directly from the census shapefiles.
