The Census Bureau is clearing its data cupboard to make room for results of the 2010 Census. Today, the bureau released 2009 state and county housing unit estimates, the last ones before decennial results are compiled.
Last week, the bureau released population estimates by age, sex, race and Hispanic origin for the nation, states and counties. The baseline for these estimates is the 2000 Census, updated with data from the American Community Survey and recent government records such as birth and death certificates, immigration statistics and building permits. The reference date for these estimates is July 1, 2009.
All sets of estimates can be found on the Census Bureau’s population estimates page.
