These maps are really interesting, although I agree that whether they are actually measuring gentrification is debateable. I would have found the site a lot easier to use if there were a big map view of the whole country where you could select from the supported regions. I was trying to see Mountain View, and finding the right setting in the drop down menu took a while (Mountain View and Los Altos are lumped in with "San Jose-Sunnyvale-Santa Clara" if anyone else is looking).
