In 1860, Idaho north of 46 degrees north latitude was part of Spokane County, Washington Territory. The 1860 federal census appears to reflect no white population, and the 1860 federal census of Cache County, Utah Territory, included some persons living in what is now the southeastern corner of the Bear Lake area. The 1870 Idaho territorial census is extant for all counties and has been indexed, although the unorganized area of Kootenai was enumerated with Nez Perce County. A portion of Bear Lake and the Franklin County area was enumerated with Cache County, Utah. An index has been compiled by the Idaho State Historical Society entitled “Missing 1870 Census of Franklin and Bear Lake Counties Idaho Found in 1870 Census of Utah” (Boise, Idaho: Williams Printing, Co., 1982). Any population in the Yellowstone National Park area of Idaho for 1880 was enumerated in the Wyoming census. An index to the 1910 federal population schedule was published by the Idaho Genealogical Society.
