Macomb County is a county located in the eastern portion of the U.S. state of Michigan, bordering Lake St. Clair, and is part of northern Metro Detroit. As of the 2020 Census, the population was 881,217, making it the third-most populous county in the state.[3] The county seat is Mt. Clemens.[4] Macomb County is part of the Detroit-Warren-Dearborn, MI Metropolitan Statistical Area. The city of Detroit is located south of the county's southern border. Macomb County contains 27 cities, townships and villages, including three of the top ten most-populous municipalities in Michigan as of the 2010 census: Warren (#3), Sterling Heights (#4) and Clinton Township (#10). Most of this population is concentrated south of Hall Road (M-59), one of the county's main thoroughfares.


The Ojibwe lived in the area for centuries before European contact, and were preceded by other cultures of ancient indigenous peoples.

The first European explorers were French, and they arrived in the area during the 17th century. Other early settlers were French fur trappers, who sometimes married Ojibwe women, and Jesuit missionaries. A Moravian colony was established in the county in the late 18th century. In addition to the original French and English settlers, later immigrants included Germans, Belgians, and others from Europe. In the 19th century the county received many European-American migrants from New York and New England, who were attracted to the area for land and booming jobs in the lumber and other resource industries.[5]

Macomb County was formally organized on January 15, 1818, as the third county in the Michigan Territory. The county was named in honor of Detroit-born Alexander Macomb, Jr., a highly decorated veteran of the War of 1812 and hero of the Battle of Plattsburg. He was made Commanding General of the U.S. Army in 1828.[1][6]

As was typical in development, the county at first encompassed a much larger area than at present. As population increased in the area, the state legislature removed territory in 1819 and 1820 to form the counties of Oakland, Lapeer, Genesee, and St. Clair.[1]

In May 2008, Macomb County voters approved the inclusion of a County Executive in a new charter to be submitted to the voters by 2010. A charter commission was elected in November 2008 for the purpose of drafting a charter for submission to Governor Granholm, which was submitted and approved and placed on the November 2009 ballot. The Charter passed with a 60.4% to 39.6% margin.[7]

According to the U.S. Census Bureau, the county has a total area of 571 square miles (1,480 km2), of which 479 square miles (1,240 km2) is land and 92 square miles (240 km2) (16%) is water.[8] The county's southeastern border with Canada is located across Lake St. Clair.

Lake St. Clair borders the county on the east.

Far northern parts of the county, such as Richmond and Armada, are often considered to be part of Michigan's Thumb region.

The county is a mix of mostly rural/agriculture to the north, and a mix of suburban and urban areas to the south.

The county government operates the jail, maintains rural roads, operates the major local courts, keeps files of deeds and mortgages, maintains vital records, administers public health regulations, and participates with the state in the provision of welfare and other social services. The county board of commissioners, which for the 2019–21 term is chaired by Bob Smith, controls the budget and creates and adopts ordinances and resolutions related to County functions. In Michigan, most local government functions — police and fire, building and zoning, tax assessment, street maintenance, etc. — are the responsibility of individual cities and townships.

The Macomb Intermediate School District serves all school districts based in the county.

Macomb County has shown Republican tendencies in statewide elections, while tending to favor Democratic candidates at the federal and local level.[19] Since the 2010s, Macomb County has shifted towards the Republicans, and after the 2020 elections the party gained control of the Board of Commissioners for the first time as well as four of the five countywide offices.[20] The county gained fame in the 1980s and '90s as a bellwether of state and national politics. Macomb's large cohort of middle-class,[21] socially conservative whites gave it one of the nation's most prominent concentrations of "Reagan Democrats".[22] Outsider candidates with a conservative-populist bent have done well there in the past, such as Pat Buchanan in 1992 and Donald Trump in 2016 and 2020.[23][24][25] Macomb County voters were primarily responsible for the failure of the Regional Transit Authority proposal to create a public transit system in the Metropolitan Detroit region.[26]

The more populated communities south of M-59 (Warren, Sterling Heights, Clinton Charter Township), closer to Detroit city proper are friendlier to Democrats. Warren leans Democratic, while Sterling Heights, after voting for Barack Obama in 2012, voted for Trump by about 12 points in both 2016 and 2020, but in 2018, voted for Gretchen Whitmer and Debbie Stabenow by 3 points, and Clinton Charter Township after voting for Obama in 2012, voted for Trump in 2016, but swung back to Whitmer and Stabenow in 2018 and Joe Biden in 2020.[27][28] The communities north of M-59 further removed from Detroit are more strongly Republican, all backing Trump in 2016 and 2020 and Bill Schuette in 2018.[29]

Major highways[]

  • I-94 (Edsel Ford Freeway) runs –west through Detroit and serves Ann Arbor to the west (where it continues to Chicago) and Port Huron to the northeast. The stretch of the current I-94 freeway from Ypsilanti to Detroit was one of the first American limited-access freeways. Henry Ford built it to link his factories at Willow Run and Dearborn during World War II. It was called the Willow Run Expressway.
  • I-696 (Walter Reuther Freeway) runs east–west from the junction of I-96, I-275, and M-5 to I-94, providing a route through the northern suburbs of Detroit.
  • M-3 (Gratiot Avenue) is a major road that runs from Marysville to downtown Detroit. The portion of the road between 23 Mile Road and New Haven Road is not numbered. Between New Haven Road and Main Street in the city of Richmond the road is part of M-19. Between Richmond and Marysville the road is not numbered.
  • M-19 starts in New Haven goes up Gratiot to Richmond. The route leaves Gratiot and goes northwest through Richmond and then north through Memphis. Then it goes north through St. Clair and Sanilac Counties and ends at M-142 between Bad Axe and Harbor Beach in Huron County.
  • M-29 begins as part of 23 Mile Road, east of I-94 and ends in Marysville.
  • M-53 which is called the Van Dyke Freeway and Christopher Columbus Freeway from 18 Mile Road in Sterling Heights to 27 12 Mile Road in Washington Township. It is also called the POW/MIA Memorial Freeway from 27 12 Mile Road in Washington Township to the freeway's end at 34 Mile Road in Bruce Township, however it is locally known as the Van Dyke Freeway. It continues as Van Dyke Road or Van Dyke Avenue north to Port Austin and south through Warren to Gratiot Avenue in Detroit.
  • M-59 (Veterans Memorial Freeway) from Utica to Pontiac, continues east as Hall Road to Gratiot Avenue and as William P. Rosso Highway to its terminus at I-94 and west as various surface roads to I-96 near Howell
  • M-97 (Groesbeck Highway) begins in Detroit at Gratiot (M-3) and ends at Hall Road (M-59).
  • M-102 (8 Mile Road), known by many due to the film 8 Mile, forms the dividing line between Detroit on the south and the suburbs of Macomb and Oakland counties on the north. It is also known as Baseline Road outside of Detroit, because it coincides with the baseline used in surveying Michigan; that baseline is also the boundary for a number of Michigan counties.

Other roads[]

  • Jefferson Avenue is a scenic highway that runs parallel to the shore of the Detroit River and Lake St. Clair. It is also the principal thoroughfare for the Grosse Pointes, where it is called Lake Shore Drive.
  • "Mile" roads: Surface street navigation in Metro Detroit is commonly anchored by "mile roads," major east–west surface streets that are spaced at one-mile intervals and increment as one travels north and away from the city center. Mile roads sometimes have two names, the numeric name (ex. 15 Mile Road) used in Macomb County and a local name (ex. Maple Road) used in Oakland County mostly.
