Maricopa County (// MARR-i-KOH-pə) is a county located in the south-central part of the U.S. state of Arizona. As of the 2010 census, its population was 3,817,117, making it the most populous county in the state, and the fourth-most populous in the United States. It is more populous than 23 states. The county seat is Phoenix, the state capital and sixth-most populous city in the country.
In 2010, the center of population of Arizona was located in Maricopa County, in the city of Mesa.
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. 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. 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.
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 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. 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.
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 county is served by three interstates (Interstate 8, Interstate 10, and Interstate 17), one U.S. Highway (US 60), and several state highways (SR 51, SR 74, SR 85, SR 87, SR 143, Loop 101, Loop 202, and Loop 303).
In the area of rail transport, the region is also served by Phoenix's light rail system. The county has no other passenger rail transport as Amtrak's Sunset Limited, which once served Phoenix, has its closest stop in Maricopa, Arizona in neighboring Pinal County. The train connects Maricopa to Tucson, Los Angeles, and New Orleans three times a week. However it does not stop in Phoenix itself.
Phoenix's major airport is Sky Harbor International Airport. Other airports that are also used are Phoenix-Mesa Gateway Airport in Mesa, Scottsdale Municipal Airport in Scottsdale, Deer Valley Airport, Phoenix Goodyear Airport in Goodyear and Buckeye Municipal Airport in Buckeye.
