History of La Paz County
La Paz County was established in 1983 after voters approved separating the northern portion of Yuma County, making it the only county to be established after Arizona became a state in 1912, and currently the second youngest county in the United States (behind the consolidated city-county of Broomfield, Colorado, which was established in 2001). The county did not have a large enough tax base to begin supporting a separate county government immediately and had to rely on state money at first. As a result, the Arizona State Legislature changed Arizona laws to make splitting other existing counties much more difficult.
