Demographic data from the US Census and American Community Survey, offered as tables (and some shapefiles with added data) ready for import into GIS software

The US Census stores its spatial data in a "Master Address File and Topologically Integrated Geographic Encoding and Referencing system" (MAF/TIGER). Researchers may download limited extracts from this database as shapefiles to use in GIS software or GIS applications. This is a very easy way to obtain (vector) shapes, which can be joined with regular data tables (such as those from Fact Finder) to generate maps that include quantitative information.

Physical geographic information is stored in the National Atlas, such as land cover, hydrography, orthoimagery and elevation data.
