An analysis of the 2010 U.S. Census shows the population was slightly overcounted, by about 0.01 percent or 36,000 people.
That means the latest census was more accurate than the 2000 Census, which had an overcount of about 0.49 percent. Census Bureau Director Robert Groves says the 2010 Census was "outstanding." But the analysis found that accuracy varied by demographics.
The 2010 Census overcounted whites by .08 percent, undercounted 2.1 percent of the African-American population, and undercounted 1.5 percent of the Hispanic population.
