People from the West Coast are seeking more affordable living in the mountain states, helping to propel nine counties in the southern half of Idaho to grow more than 25% in the past decade.
Many of the new residents migrated from California, Washington and Oregon, Dale said.
Several counties in the state’s southeast quadrant grew by more than a quarter. Madison and Jefferson Counties both grew 37%.
Idaho became slightly more diverse in the past decade. The population in 2000 was 88% non-Hispanic white; now it is 84%. The non-Hispanic black population, less than 1% of the state, went from 0.4% to 0.6%: 8,875 people.
Hispanics, who can be of any race, account for 11% of the population, up from 8% in 2000.
“People don’t think about Idaho having any diversity at all,” said William Frey, a demographer at the Brookings Institution. “Hispanics account for a lot of the growth in the state.”
