Populations in local counties saw a slight decrease in 2012 as the state continued with strong growth, according to a recent population estimate report by the U.S. Census Bureau.
Clinton County population went from 49,086 in 2011 to 48,717 in 2012. The county lost 369 residents for a decrease of 0.8 percent and a consistent ranking of 11 in the state.
Jackson County saw little change with a population of 19,712 in the 2012 report, down 16 residents or 0.1 percent from 19,728 in 2011. Jackson ranks 36th out of 99 counties in the state.
Across the river in Illinois, Whiteside and Carroll counties also had a subtle decrease in population growth. The population in Whiteside County decreased by 0.7 percent from 58,240 in 2011 to 57,846 in 2012. According to the U.S. Census Bureau, 394 residents have left since 2011, putting the county at 25th out of 102 counties in the state.
Carroll County ranked 74th for population growth with a 1.2 percent decrease from 2011. Population in the county went from 15,195 in 2011 to 15,011 in 2012 for a loss of 184 residents.
Dallas County is the fastest growing county in Iowa, ranking 14th in the nation in growth among counties according to the census. Dallas County grew by 8.8 percent 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. Thirty-one 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.
The new county population estimates, rankings and components are on the Iowa Library Services-State Data Center web site at 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.
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.
