Last month, the U.S. Census Bureau released July 1, 2009, population estimates for each of the nation’s counties and metropolitan and micropolitan statistical areas that show migration results during the years of the housing and economic downturn. Those statistics show that some counties in Florida, Arizona, New Mexico and California saw slower growth in populations and some even showed a decrease in population growth as those areas were hardest hit from the real estate slow down.
The new estimates are not 2010 Census population counts. They are, however, the last estimates to use 2000 Census results as a base. The 2010 Census population totals will be used to apportion seats in the U.S. House of Representatives. By April 1, 2011, the Census Bureau must release data for counties, cities and other small geographic areas so that states can proceed with redistricting.
