New U.S. Census estimates show Iowa’s population continued to increase slowly in the last year and now numbers a little over 3.1 million. The July 1, 2019, estimate released Monday was up over 108,000 from the 2010 population. Iowa’s population would have been significantly lower if not for international migration, which since 2010 has added nearly 48,000 people to the state. That migration offset nearly 30,000 residents who moved from Iowa to other states during that period. The national population was estimated at 328.2 million.
