Data presented for 2010 through 2011 are Vintage 2011 population estimates. Each year the U.S. Census Bureau revises their post-2010 estimates. Therefore, data presented here may differ from previously published estimates. Figures for 1990, 2000, and 2010 represent revised population estimates for July 1, 1990, July 1, 2000, and July1, 2010 - not actual Census counts from April 1, 1990, April 1, 2000, and April 1, 2010.
