DEC. 20, 2017 — Idaho was the nation’s fastest-growing state over the last year. Its population increased 2.2 percent to 1.7 million from July 1, 2016, to July 1, 2017, according to the U.S. Census Bureau’s national and state population estimates released today.
Following Idaho for the largest percentage increases in population were: Nevada (2.0 percent), Utah (1.9 percent), Washington (1.7 percent), and Florida along with Arizona (1.6 percent).
“Domestic migration drove change in the two fastest-growing states, Idaho and Nevada, while an excess of births over deaths played a major part in the growth of the third fastest-growing state, Utah,” said Luke Rogers, Chief of the Population Estimates Branch.
