Canyon County sits in southwest Idaho, with its westernmost border adjacent to the state of Oregon.  Canyon County is so named because of the spectacular basalt cliffs along the Snake River canyons.

Canyon County has experienced extraordinary growth during the past several years, having some of the highest population percentage growth in the Treasure Valley.  However, sales prices began to decline in 2008, and experienced more declines in 2009.  Short sales and foreclosures are a significant portion of the SFR market, causing the average and median sales prices for residential properties to continue their downward trend. 

Most of Canyon County is included in the Boise-Nampa MSA, which includes more than 500,000 residents.

Canyon County is home to the College of Idaho and Northwest Nazarene University, and has a nice mix of commercial and agricultural businesses as economic bases.  The Simplot Company has a significant number of its operations throughout Canyon County.  Sunny Slope along the Snake River on the southwestern edge of the county has several good-sized fruit operations.

• Caldwell (county seat), population 37,056
