The Census Data Mapper is a web mapping application intended to provide users with a simple interface to view, save and print county-based demographic maps of the United States. The data are from the 2010 Census.
Reference Maps include a variety of map types that show the boundaries and names of geographic areas for which the Census Bureau tabulates statistical data. In some cases, the name is only in the form of a geographic code, such as a census block number. Some types of reference maps include geographic features and their identifiers that are coincident with the boundary. Examples are roads and water features. Reference maps can include additional features such as railroads to aid users in orienting themselves to the area depicted on the map.
My Congressional District gives you quick and easy access to selected statistics collected by the U.S. Census Bureau through the American Community Survey (ACS) and County Business Patterns (CBP). The ACS provides detailed demographic, social, economic, and housing statistics every year for the nation's communities. CBP provides annual statistics for businesses with paid employees at a detailed geography and industry level. My Congressional District is powered by ACS and CBP data through the Census Application Programming Interface (API). - See more at: http://www.census.gov/mycd/application/#sthash.Su3DrcNd.dpuf
Thematic maps are data maps of a specific subject or for a specific purpose. Statistical thematic maps include a variety of different map types such as choropleth or shaded maps, dot maps, proportional symbol maps, and isarithmic maps. Special purpose maps generally concentrate on a single theme, such as the Centers of the Population Centers of the U.S. between 1790 and 2000.
