Cities and towns

[edit]

Marion County has a consolidated city-county government, known as Unigov, in which only four municipalities retain full government autonomy (including a mayor and city council) as "excluded cities". The remaining municipalities within the county are "included towns" and exercise very limited authority, mainly in zoning and appointing their own police departments and maintaining some of their own municipal services and town identities. They retain the ability to levy taxes for these purposes.

Politics

[edit]

The northern two-thirds of Marion County is in Indiana's 7th congressional district, which is held by Democrat André Carson. Indiana's 6th congressional district, which runs along the southern third of the county, is held by Republican Jefferson Shreve. The county is represented by 15 seats in the Indiana House of Representatives, 86th through 100th districts, with ten seats held by Democrats and five by Republicans. In the State Senate Marion County is divided among nine districts, which are held by two Democrats and seven Republicans. The Senate districts are numbered 28 through 36.

The Indianapolis City-County Council is the combined legislative body of Indianapolis and Marion County. The consolidated government, known as Unigov, was formally established in 1970 upon the merger of the city government with the county government. The council passes ordinances for the city and county, and makes appointments to certain boards and commissions.

For most of the 20th century, Marion County was considered one of the most conservative urban counties in the nation. Between 1896 and 2000, it went Democratic only four times, in the national landslides of 1932, 1936 and 1964 as well as 1912 when Woodrow Wilson won a plurality in the county. The Republican edge began to lessen considerably in the 1990s, and in 2004 John Kerry became the first Democrat since Lyndon B. Johnson in 1964 to carry the county. The trend continued in 2008 and 2012 with Barack Obama showing strongly in Marion County, winning 63% and 60% of the vote respectively. Hillary Clinton won it with 58 percent in 2016, and Joe Biden took 63 percent in 2020. Biden's 247,772 votes is the highest number of votes a candidate has ever received in the county. It is now one of the few Democratic bastions in traditionally heavily Republican central Indiana, and in the 2020 and 2024 elections, it was the most Democratic county in the entire state.<ref>https://uselectionatlas.org/RESULTS/</ref>

The six northern and central townships lean more Democratic, especially Center Township containing Downtown Indianapolis, and Pike Township in the northwestern corner with an African-American majority. In contrast, the three less populated southern townships with a higher Caucasian population (Decatur, Perry and Franklin) lean more Republican.<ref>Template:Cite news</ref>
