In-Migration Accounted for 73 Percent of Idaho’s Population Increase
Idaho’s population continued to become more urbanized from mid-2017 to mid-2018, with nearly 73 percent of the growth coming from outside the state, newly released data from the U.S. Census Bureau shows. The data provides additional detail at the county level to the January release that showed Idaho’s 2.1 percent population increase tied with Nevada as the fastest-growing state in the nation.
The Boise Metropolitan Statistical Area (MSA) population grew by 2.9 percent – the eighth fastest among the nation’s 383 other MSAs. The five counties that comprise the Boise MSA – Ada, Boise, Canyon, Gem and Owyhee counties – increased by 20,346 people accounting for 58 percent of the state’s total increase of 35,304. The concentration of more than half of Idaho’s growth in the Boise MSA typifies the continued steady shift toward urbanization of the state’s population from rural to urban counties.
