Earlier this week the Census Bureau released new figures for population growth in U.S. counties. It has previously released figures that show that Arizona, Nevada, and Idaho were the three fastest growing states by percentage increase in the United States between mid 2005 and mid 2006 (3.6, 3.5, and 2.6 percent). Idaho has been the third fastest growing state for two years in a row now.
The county numbers released this week show Ada county to be the fourth fastest growing county in the state, by percentage. Ada's growth of 13,617 last year was a 3.9 percent increase. Valley county (think McCall) was first with 6.3 percent, followed by Canyon (Nampa-Caldwell) with 5 percent, and Teton (Driggs, on the eastern edge of the state) with 4.6 percent in third place. Canyon county made it to 39th on the list of 100 fastest growing counties in America, the only county in Idaho on the list.
The Treasure Valley area of Southwest Idaho has approximately 41 percent of the state's population... that's more than 607,000 people! Of that number, Ada and Canyon counties make up more than 532,000 of those folks. Growth in these two counties has been very strong for more than a decade now, with a 23 percent increase just since 2000! And as the word gets out about all that Boise and the Treasure Valley has to offer, there is no reason for these growth trends not to continue.
