Thanks to Rebecca, Kathryn and the other good people at the Google Research | Structured Data Group, a map I created to show the distribution of Americans living in urban areas for a story about the need to fund urban mass transit is now fully functional. If I don’t say so myself, the map is pretty cool: when you point your cursor over each of the states, a little grey window pops up to show what percentage of each state’s residents live in an urban area. Check it out below — and if you want to view the original story, click here.
