PolicyMap has done an excellent job of curating publicly available data and publishing maps by several administrative boundary types. The
PolicyMap web map provides a quick way to review data such as from the Community Reinvestment Act for low-medium income housing, population density, economic data, etc.
It's used by many non-profits to visually understand trends of geospatial relationships.
It's another example of #coolmap
