Maricopa County ( /ˌmærɨˈkoʊpə/ marr-i-koh-pə) is located in the south-central part of the U.S. state of Arizona. As of April 1, 2010, its population is an estimated 3,817,117, the most populous in the state,^[1] which ranks fourth among the nation's counties and is greater than the population of 23 states.^[2] Maricopa County is also one of the largest counties in the United States by area having a land area greater than that of seven states. The county seat is Phoenix,^[3] which is Arizona's largest city and capital. The center of population of Arizona is located in Maricopa County, in the town of Gilbert.^[4] It is by far Arizona's most populous county, encompassing well more than half of the state's residents.

The population explosion is evident in a 2007 Forbes study which ranked four of Maricopa County's municipalities in the top ten fastest-growing cities in the nation. Those included Buckeye as the second-fastest-growing city, Surprise and Goodyear as 3rd and 4th, and Avondale as 9th.^[5] All four of these cities are located in the growing "West Valley", which is the area of Maricopa County to the west of the city of Phoenix.

There are five Indian reservations located in the county.^[6] The largest of these are the Salt River Pima-Maricopa Indian Community (east of Scottsdale) and the Gila River Indian Community (south of Phoenix).

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. In 2008, the county was the most populous in the nation to be won by John McCain over Barack Obama.

Despite its 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 slim 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.^{[citation needed]} Each member serves for a period of four years, and may be continuously reelected. The Board of Supervisors acts in the capacity of executive authority for the county within the statutes and powers prescribed by Arizona state law. In this respect the Legislature of the State of Arizona is, in effect, the legislative body of the county, 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. Unlike cities and towns in Arizona, each county is not a chartered government and is considered both politically and legally a sub-division of the state.

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 current sheriff is Joe Arpaio, who has labeled himself "America's Toughest Sheriff" due to his flamboyant and often controversial management of office.^[12]

As Maricopa County is home to almost 60 percent of the state's population, it dominates Arizona's politics. Six of the state's eight congressional districts take in significant portions of the county, and most of the state's most prominent elected officials live there.
