The county seat is Pontiac. Oakland County is part of the Detroit metropolitan area, though the city of Detroit is located in neighboring Wayne County. It is among the ten highest income counties in the United States with populations over one million people. Oakland County is home to 62 cities, villages and townships. These communities range from blue-collar, inner-ring suburbs like Ferndale and Hazel Park, to affluent cities such as Birmingham, Bloomfield Hills, West Bloomfield Township, Oakland Township and Franklin. The white-collar cities of Troy, Southfield, Farmington Hills, and Auburn Hills host a rich mix of Fortune 500 companies and international firms. The cities of Royal Oak and Ferndale attract many young people to their mature, bohemian downtowns, which have many restaurants, shops and night clubs. Many places such as Waterford Township, Independence Township, and Springfield Township to name a few have a variety of businesses and incomes. Oakland County is also home to Oakland University, a large public institution that straddles the Auburn Hills and Rochester Hills border. The county's knowledge-based economic initiative, coined "Automation Alley", is one of the largest employment centers for engineering and related occupations in the United States.
