Two Louisiana parishes were the nation’s fastest-growing counties in 2007, according to recent population estimates by the U.S. Census Bureau. St. Bernard County, which led the nation in population loss after Hurricane Katrina in 2005, saw its population increase 42.9 percent from July 2006 to July 2007. Orleans county, also hit by Katrina, rose 13.8 percent in the same period. Nine of the top ten fastest-growing counties were located in the South or West.
Of the ten counties that had the greatest numerical increase in population, half were in Texas, two were in North Carolina, one was in California and one was in Nevada. Maricopa County, Ariz. led the pack with an increase of 102,000 residents between 2006 and 2007.
Although the population in Los Angeles County decreased by 2,000 from 2006, it remained the nation’s most populous county with 9.9 million people.
