December 6, 2010 - U.S. Census Bureau Director Robert Groves briefed the media on the release of the 2010 Demographic Analysis estimates. The Census Bureau released five series of national-level estimates of the population by age, sex, two race groups (black and non-black) and Hispanic origin (for under age 20). Demographic Analysis estimates are developed from historical vital statistics and estimates of international migration. Although not 2010 Census counts, these estimates provide one way of measuring the size of the U.S. population and will be used to analyze the 2010 Census results.
