Idaho’s population grows by 53k from 2020 to 2021

The newest data released shows how the population growth was distributed around the state. While the largest numerical growth was concentrated in urban counties, most of Idaho’s rural counties experienced proportional growth. In all, 38 of Idaho’s 44 counties grew by at least 1%, and every county grew faster than the national average growth rate, except for Clark County, which is Idaho’s least populous county.

Population growth continued to be strong in Idaho’s three largest counties — Ada, Canyon and Kootenai — from 2020 to 2021. These three counties collectively accounted for just less than 50% of the state’s total population, and they accounted for 31,491 of the state’s new residents, or 59% of the population growth. Ada County’s population exceeded half a million for the first time, growing to 511,931.

Despite the continued trend toward urbanization, several rural Idaho counties showed significant growth, with six rural counties growing by faster than 4%. Boise County was the fastest-growing county at 5.8%.
