Just about any stat you want is at the Census Bureau Web site, but finding it can sometimes be diffiucult.
The American Community Factfinder page is probably the best place to start. You can get quick population, housing, economic, and geographic data by just typing a zip, city, town or county.
Check out the Newsroom . Here are some of the links you'll find there: the latest news releases and links to the stats; a Facts and Features link that has Factoids for holidays, special observances and feature stories; a Media Services link for reporters and editors that has contact information for specialists by subject area.
The Minority Links page has links to the latest data on racial and ethnic U.S. populations.
