View New Population Estimates for Each County

New Census Bureau data shows which counties are gaining and losing residents.

The U.S. Census Bureau published updated population estimates Thursday, tallying numbers of residents for counties and metropolitan areas.

Much of the nation’s fastest-growing counties are concentrated in the Sun Belt, with parts of Florida and Texas experiencing notable population gains since 2013. Rural counties in western North Dakota also continued to add residents at a rapid pace as a result of growth in the energy sector.

Of larger counties with at least a half million residents, the top three fastest-growing jurisdictions between 2013 and 2014 are all found in Texas: Fort Bend County (+4.7%), Montgomery County (+3.8%) and Denton County (+3.3%). Wayne County, Mich., and Cuyahoga County, Ohio, recorded the steepest estimated population decreases, but the losses represented declines of less than 1 percent.

The following map shows population growth over a 12-month period ending last July, with counties registering the highest percentage changes shown in green. Open an interactive map to view data for each county.
