The steady shift of Idaho’s population from rural to urban counties continued between July 1, 2016 and July 1, 2017, according to estimates released Thursday by the U.S. Census Bureau.

Six urban counties – Ada, Canyon, Kootenai, Bonneville, Bannock and Twin Falls – had a combined population of 1,116,173, accounting for 75 percent of the growth in the state’s population and 65 percent of overall population. The state’s total population was estimated at 1,716,943.

Adams had the highest percentage gain at 5 percent, but less than 200 new people. Fifteen counties had a percent increase larger than the state’s 2.2 percent gain. Clark County’s population increased at the same rate as the state. Forty-two counties showed population increases ranging from 12,580 people in Ada County to 18 additional people for Camas County. Six counties reported growth in excess of 1,000 – Ada (12,580), Canyon (5,588), Kootenai (4,493), Bonneville (2,570), Twin Falls (1,588) and Bonner (1,217).

Two counties experienced a decrease in population – Clearwater’s population decreased by nine people and Power’s population dropped by 61 people.

Population estimates show the net migration in Idaho was 26,525, or 1.5 percent of total population. Nearly 93 percent of the state’s population growth was due to people moving into the state. More people moved into 40 of Idaho counties than moved out, adding 27,334 people. The increase from net migration ranged from 10,268 in Ada County to 11 in Cassia County. Four counties – Gooding, Madison, Minidoka and Power - experienced losses in net migration – 809 more people left than moved in. The 12 counties that make up Idaho’s five Metropolitan Statistical Areas accounted for 60 percent of the state’s net migration.

Births and deaths are two other major components in population changes, commonly referred to as natural increases. Statewide there were 22,981 births between July 1, 2016, and July 1, 2017, and 12,653 deaths resulting in a gain of 10,328 people. Ada County reported the largest number of births - 5,170 - and deaths - 2,899 - for a net gain of 2,271 people.

Clark County experienced the smallest number of births, numbering eight with the fewest deaths at two. Three Idaho counties had a natural increase (births minus deaths) of more than 1,000 – Ada (2,271), Canyon (1,763), and Bonneville (1,147). Seven counties experienced net losses – Lemhi (4), Benewah (7), Bonner (7), Idaho (11), Boise (12), Shoshone (19) and Clearwater (37).
