City-Data.com (http://www.city-data.com/) - We've collected and analyzed data from numerous sources to create as complete and interesting profiles of all U.S. cities as we could. We have tens of thousands of city photos not found anywhere else, hundreds of thousands of maps, satellite photos, stats about residents (race, income, ancestries, education, employment...), geographical data, state profiles, crime data, housing, businesses, birthplaces of famous people, political contributions, city government employment, weather, hospitals, schools, libraries, houses, airports, radio and TV stations, zip codes, area codes, user-submitted facts, similar cities list, comparisons to averages... If you ever need to research any city for any reason, from considering a move there to just checking where somebody you know is staying, this is the site for you.

I visited that site recently and kinda question some of the numbers compare to what I've seen "officially" listed for the same city. Some are definitely outdated - using figures from several years ago when more recent statistics are available. They also add this disclaimer at the bottom of their website:
