Iowa's population is growing but not as fast as most other states.
The State Data Center says Iowa's population has grown 3.6% since 2010 to 3.156 million people. Iowa's slower growth rate dropped it from 30th to 31st in population in the U.S. Utah, which boats the fastest growing state population rate at 14%, leaped Iowa.
Iowa's growth rate ranks 28th in the country, below the national growth rate of 6%. That is still better than Iowa's some of Iowa's neighbors, including Illinois which was one of two states to lose population. West Virginia was the other.
Iowa's growth is mostly attributable to more births than deaths in the state. International migration also added 48,000 to Iowa's population. That overcame a net migration of Iowans moving out of the state, with 21,000 more people moved away from Iowa than moved to the Hawkeye state.
Washington, D.C. outpaced all states in population growth at 16.7%.
