Maricopa County (/ˌmærɪˈkoʊpə/ MARR-i-KOH-pə) is a county in the south-central part of the U.S. state of Arizona. The U.S. Census Bureau estimated its population was 4,307,033 as of 2017,^[2] making it the state's most populous county, and the fourth-most populous in the United States. It is more populous than 23 states. The county seat is Phoenix,^[3] the state capital and fifth-most populous city in the United States.

Maricopa County is the central county of the Phoenix-Mesa-Glendale, AZ Metropolitan Statistical Area.

Maricopa County was named after the Maricopa Indians.^[4] There are five Indian reservations located in the county.^[5] The largest are the Salt River Pima-Maricopa Indian Community (east of Scottsdale) and the Gila River Indian Community (south of Chandler).

Geography

According to the U.S. Census Bureau, the county has a total area of 9,224 square miles (23,890 km²), of which 9,200 square miles (24,000 km²) is land and 24 square miles (62 km²) (0.3%) is water.^[6] Maricopa County is one of the largest counties in the United States by area, with a land area greater than that of four states. From west to east, it stretches 132 miles (212 km) and 103 miles (166 km) from north to south.^[7] It is by far Arizona's most populous county, encompassing well over half of the state's residents.

Government, policing, and politics

Government

The governing body of Maricopa County is its Board of Supervisors. The Board of Supervisors consists of five members chosen by popular vote within their own districts. Currently, the Board consists of four Republicans, each representing districts in the more affluent or conservative districts of the county, and one Democrat, representing the largest district. Each member serves a four-year term, with no term limits.

Maricopa County sheriff

The Maricopa County Sheriff's Office provides court protection, administers the county jail, and patrols the unincorporated areas of the county plus incorporated towns by contract.

Politics

Maricopa County has a long history of being a Republican Party stronghold. While the city of Phoenix leans towards the Democratic Party, along with some other small areas within the county, the rest of the county tends to vote heavily Republican. Every Republican presidential candidate has carried Maricopa County since 1948. This includes the 1964 presidential run of native son Barry Goldwater, who would not have even carried his own state had it not been for a 21,000-vote margin in Maricopa County. It is currently the largest county in the country to vote Republican. Since 1964, Democrats have only kept the margin to single digits three times–in 1992, 1996, and 2016.

Despite its apparent political leanings, Maricopa County voted against Proposition 107 in the 2006 election. This referendum, designed to ban gay marriage and restrict domestic partner benefits, was rejected by a 51.6–48.4% margin within the county, and statewide by a similar margin. Two years later, however, a majority of county residents voted to pass the ultimately successful state constitutional amendment banning same-sex marriage.

The County Board of Supervisors consists of five members chosen by popular vote within their own districts. Currently, the Board consists of four Republicans, each representing districts in the more affluent or conservative districts of the county, and one Democrat, representing the largest district.^[23] Each member serves a four-year term, with no term limits.

Unlike cities and towns in Arizona, counties are politically and legally subordinate to the state, and do not have charters of their own. The Board of Supervisors acts in the capacity of executive authority for the county within the statutes and powers prescribed by Arizona state law. The state legislature devotes considerable time to local matters, with limited discretion granted to the Board of Supervisors on minor ordinance and revenue collection issues. Chair of the Board is held by one member for a period of one year, and is selected by the Board members themselves through public hearing.

The election of the County Sheriff, County Attorney, County Assessor, County Treasurer, Superintendent of Schools, County Recorder, Constables, Justices of the Peace, Clerk of the Superior Court, and retention of Superior Court Judges are also determined by popular vote.

The county's dominant political figure for over two decades (from 1993 to 2017) was Sheriff Joe Arpaio, who had dubbed himself "America's Toughest Sheriff" and gained national notoriety for his flamboyant and often controversial practices and policies.^[24]

As Maricopa County is home to almost 60 percent of the state's population, it dominates Arizona's politics. Eight of the state's nine congressional districts include at least some portion of the county, and five of said districts have their population center located there. Most of the state's most prominent elected officials live in the county, as well.

The train connects Maricopa to Tucson, Los Angeles, and New Orleans three times a week. However it does not stop in Phoenix itself.
