Named for President Andrew Jackson, Jackson County was formed in 1852 from the southwestern portion of Lane County and the unorganized area south of Douglas and Umpqua Counties. It originally included lands which now lie in Coos, Curry, Josephine, Klamath and Lake Counties. After a history of boundary changes, battles, and settlements, the County now covers 2,802 square miles, of which 2,785 square miles is land and 17 square miles is water, and has grown to have the sixth largest population of all Oregon counties.
The County is governed by a three-member Board of Commissioners
, an elected body responsible for many broad issues in the region, such as forest planning, water supply issues, regional land use planning, air quality, transportation, emergency management and economic development. The Board also works with the County’s 11 cities on matters of mutual concern, and serves the citizens of Jackson County by resolving complaints and legislating where necessary.
Service under Jackson County jurisdiction include the library system, the Airport, the Expo/Fairgrounds, County Roads and Parks, Health and Human Services, voting and voter registration, and the Sheriff and Community Justice departments.
