PolicyMap integrates geographic mapping with extensive data on health, demographics, education, economy, income, quality of life, etc. Users select a geographic region (city, state, country, census tract, block group, congressional district, school district, etc.) and can use data derived from more that 150 sources. Users can also create a customized geographic region (e.g. DC/Maryland/Virginia) and upload their own data. PolicyMap's 3-layer maps allow users to define up to three data parameters and will identify areas on the selected map that match those parameters.
