Census
The area now known as Gem County was first part of Boise County (1863). When Ada County was formed in 1864, it included portions of what are now Gem and Canyon Counties. When Canyon County was formed in 1891 it included a portion that later became southern Gem County. Gem County as we know it today was created March 1915 from Canyon County and Boise County. (see Book 1, page 33 map showing old Boise/Canyon county line and Westview Mining District (Pearl). The map was filed in Canyon County Oct. 27, 1897, and certified Nov. 11, 1915 when we became Gem County.)
