Check out this great website called "The Policy Map". It provides an online interactive mapping tool so you can access data about many different domains of society. Think of it as an advanced version of Google Maps for the mapping of communtiy data to help make more informed policy decisions. The Policy Map includes data for the entire United States at many different scales. You can even type in your own address to check out an indicator that you feel is important to your own specific community. The city of Philidelphia has tweaked the Policy Map to create this customized version, making it possible to zoom even further, to consider data at the scale of census tract.
Mapping "mash-ups" like these are similar to what we are doing here at SCOPE these days; tailoring resources for the sake of generating local innovations here in Sarasota County. We are eager to share these efforts with our community soon.
