La Paz County is the 15th county in the U.S. state of Arizona, located in the western part of the state. As of the 2020 census, its population was 16,557,[1] making it the second-least populous county in Arizona. The county seat is Parker.[2] The name of the county is the Spanish word for "the peace", and is taken from the early settlement (now ghost town) of La Paz along the Colorado River.
History[]
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, Arizona laws were changed to make splitting other existing counties much more difficult.
Under the revised Arizona laws, a county shall not be formed or divided by county initiative unless each proposed county would have all of the following characteristics: (1) at least three-fourths of one percent of the total state assessed valuation and at least the statewide per capita assessed valuation; (2) a population of at least three-fourths of one percent of the total state population according to the most recent United States decennial census; (3) at least one hundred square miles of privately owned land; (4) common boundaries with either (a) at least three other existing or proposed counties; or (b) at least two other existing or proposed counties and the state boundary.[3] A county formation commission is required to be formed to evaluate the feasibility of the proposed county.[4] A proposal to divide a county must be approved by a majority of the votes cast in each proposed new county.[5]
The Colorado River Indian Reservation is located in the western portion of the county. Part of the reservation extends westward into San Bernardino and Riverside counties in California.
Geography[]
According to the U.S. Census Bureau, the county has a total area of 4,514 sq mi (11691 km2), of which 4500 sq mi (11655 km2) is land and 14 sq mi (36 km2) (0.3%) is water.[6]
The area that now makes up La Paz County was formerly part of Yuma County.
