Jefferson County is part of the Idaho Falls, ID Metropolitan Statistical Area.

The Salt Lake City to Virginia City Stagecoach was established through the area in 1864. Stops were established at Market Lake (Roberts), Sand Hole (Hamer), and Camas. Small settlements grew up around the stagecoach stops with the most significant development occurring at Market Lake. The county's first post office was established at Market Lake on July 29, 1868 when the post office at Eagle Rock was relocated there. Initial settlement at Mud Lake also originated in 1868.
The Utah and Northern Railway reached Camas on July 3, 1879, bringing with it a new wave of settlement, particularly at Camas and Market Lake. Mormon settlement of the county began when John R Poole settled the Menan area in April, 1879 with the settlement initially named Poole's Island. Settlement followed at Lewisville in 1882, Rigby in 1883 and Ririe in 1888. The Camas and Market Lake precincts are the first to emerge in census data under Bingham County in 1890. At that point, 379 residents were enumerated in the Camas precinct and Market Lake counted 218. By the 1900 census, precincts were added for Lewisville, Menan, Rigby, and Rudy (located between Ririe and Rigby). Together with Camas and Market Lake precincts, they contained a population of 3,046. By 1910 there were 10 precincts that would become part of Jefferson County three years later with additional precincts added for Grant, Hamer, Labelle, and Lorenzo. The 1910 census population for those precincts was 5,535.
