Urban affairs & planning: Analytical tools & quantitative skills

Policy Map offers both extensive data and mapping options about communities across the US, especially for topics of interest for public policy. Data are aggregated from multiple sources and normalized to map across different geographical levels, from census tracts and ZIP codes to states. Data reports may be downloaded without maps. Policy Map also permits users to upload and map their own data. Focus is on information compiled since the early 2000s.
