My sense of my neighborhood and social spaces are imprecise and vague, based on a general feeling about how fun or wealthy or diverse they happens to be. I suspect that this is true for most people. More importantly, I’m skeptical whether quantifying these things adds to any of my experiences of them.
In any case, this web site, city-data.com (via preposterous universe), provides a host of statistical information on cities and neighborhoods in the United States. Surfing around it is fun. To compare my old neighborhood, in the East Village (zip code 10009), with my new one in Boerum Hill (zip code 11217):
