Maricopa County is the central county of the Phoenix-Mesa-Chandler, AZ Metropolitan Statistical Area. The Office of Management and Budget renamed the metropolitan area in September 2018. Previously, it was the Phoenix-Mesa-Glendale metropolitan area, and in 2000, that was changed to Phoenix-Mesa-Scottsdale.
Maricopa County was named after the Maricopa Native Americans. There are five Native American Reservations located in the county. The largest are the Salt River Pima-Maricopa Indian Community (east of Scottsdale) and the Gila River Indian Community (south of Chandler).
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. Maricopa County is one of the largest counties in the United States by area, with a land area greater than that of four other US states. From west to east, it stretches 132 miles (212 km) and 103 miles (166 km) from north to south. It is by far Arizona's most populous county, encompassing well over half of the state's residents. It is the largest county in the United States to have a capital city.

Government, policing, and politicsEdit
The governing body of Maricopa County is its Board of Supervisors. The Maricopa County Board of Supervisors consists of five members chosen by popular vote within their own districts. Currently, the Board consists of four Republicans and one Democrat. Each member serves a four-year term, with no term limits.
Maricopa County sheriffEdit
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.
Prior to 1960, Maricopa County voted for the winner in every election. However, for much of the time after World War II, Maricopa County was one of the more conservative urban counties in the United States. While the city of Phoenix has leaned Tossup in recent years, most of the rest of the county was strongly Republican. Until 2020, every Republican presidential candidate since 1952 had carried Maricopa County. This includes the 1964 presidential run of native son Barry Goldwater, who would not have carried his own state had it not been for a 21,000-vote margin in Maricopa County. Until 2020, it was the largest county in the country to vote Republican. Since 1964, Democrats have held the margin within single digits only four times–in 1992, 1996, 2016, and 2020. In 2020, Joe Biden became the first Democrat in 72 years to win the county, which flipped Arizona to the Democratic column for the first time since 1996 and only the second time since 1948. Furthermore, Biden became the first presidential candidate to win more than one million votes in the county. This makes Maricopa County the third county in American history to cast more than one million votes for a presidential candidate. The county is also a statewide bellwether, voting for the statewide winning candidate in all elections except 1996.
Despite its consistent Republican allegiance since 1952, its fast-growing Hispanic population and influx of conservative retirees and Mormons, which were traditionally conservative voting blocs but were increasingly skeptical of President Donald Trump, signaled that it was a crucial bellwether in the 2020 election.

Despite its political leanings at the time, 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 a successful state constitutional amendment banning same-sex marriage. The amendment was later invalidated by the Supreme Court's 2015 ruling in Obergefell v. Hodges, which declared that same-sex marriage is a fundamental right in the United States.
Unlike cities and towns in Arizona, counties are politically and legally subordinate to the state and do not have charters of their own. The county Board of Supervisors acts under powers delegated by state law, mainly related to minor ordinances and revenue collection. With few exceptions, these powers are narrowly construed. The state legislature devotes considerable time to local matters, with legislative approval required for many routine local issues. The chairperson of the board presides for a one-year term, selected by the board members during a public hearing.
The County Sheriff, County Attorney, County Assessor, County Treasurer, Superintendent of Schools, County Recorder, Constables, Justices of the Peace, and Clerk of the Superior Court are elected by the people. Retention of Superior Court Judges is also determined by popular vote.
The county's dominant political figure for over two decades (from 1993 to 2017) was Sheriff Joe Arpaio, who called himself "America's Toughest Sheriff" and gained national notoriety for his flamboyant and often controversial practices and policies.
Maricopa County is home to 62 percent of the state's population, thus dominating Arizona's politics. For example, in the 2018 Senate election, Democrat Kyrsten Sinema carried the county en route to becoming the first Democrat to win a Senate seat in Arizona since 1988. She won the county by over 60,000 votes, more than enough for the victory; she won statewide by 55,900 votes. All but one of the state's nine congressional districts include part of the county, and five of the districts have their population center located there. Most of the state's prominent elected officials live in the county. Further underlining Maricopa County's political dominance, Biden's margin of 45,109 votes was more than enough to carry the state; he only won Arizona by 10,457 votes.

The Democratic victory -- declared days after CNN projected Biden's win in the presidential race -- was anchored by Maricopa County, home to Phoenix and nearly 60% of all people in the state. Maricopa is the fastest-growing county in the country, transforming over the last two decades into a sprawling mass of metropolitan hubs, sun-scorched planned communities and bustling strip malls.
