Census 2010 data is being released - let the analyzing begin!
While US Government agencies like the Bureau of Economic Analysis issue a near constant stream of useful information, the gold standard of demographic information for the United States has always been the Census.
While continued funding for the Statistical Abstract of the United States is still up in the air, the Census Bureau has begun releasing information from the 2010 United States Census. Data is available on the Census Bureau website, and in the American Fact Finder.
As mandated by Article 1, Section 2 of The Constitution of the United States of America, the Census has been collected since 1790.
