Dallas County is the fastest growing county in Iowa, ranking 14th in the nation in growth among counties according to population estimates released by the U.S. Census Bureau. Dallas County grew by 8.8% since the 2010 census and added 5,382 residents for a total population of 71,967. The new estimates show 68 of Iowa's counties losing population since 2010. 31 counties have gained residents since the 2010 census.
The latest Census Bureau release also includes information about births, deaths, and migration in Iowa and its counties. Between 2010 and 2012, Iowa gained 9,269 residents from other nations and lost 3,274 residents to other states for a net migration of 5,995. Births outnumbered deaths by 22,494. Among counties, 17 counties experienced more people moving in than moving out and 41 counties recorded more births than deaths since the 2010 census.
Gary Krob, coordinator of the Iowa Library Service's State Data Center program, says that the current estimates show that Iowa's population growth continues to be the strongest in its metropolitan areas. "Of the 31 counties in our state that experienced population growth, 88.4% of that growth occurred in seven counties. Those seven counties were Polk, Dallas, Johnson, Linn, Scott, Story, and Dubuque."
The new county population estimates, rankings, and components are on the Iowa Library Services-State Data Center web site at http://www.iowadatacenter.org.
These new estimates from the Census Bureau are based on administrative data for births and deaths and estimates of migration since the 2010 census. Caution is urged in making year-to-year comparisons of population estimates. When the Census Bureau releases new estimates for the current year it also revises estimates for previous years in the decade.
The U.S. Census Bureau Population Estimates Program prepared the latest population estimates in partnership with the Federal-State Cooperative Program for Population Estimates. The State Data Center is part of Iowa Library Services and is a member of the Federal-State Cooperative Program for Population Estimates.
