Jefferson (proposed Pacific state)

Jefferson, proposed officially as the State of Jefferson is a proposed U.S. state that would span the contiguous, mostly rural area of Southern Oregon and Northern California, where several attempts to separate from Oregon and California, respectively, have taken place. The region encompasses most of Northern California's land but does not include San Francisco or other Bay Area counties that account for the majority of Northern California's population.
