Cities and townsEdit
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. Since many of these included towns were and remain fairly wealthy and influential within the county, they can still have considerable unofficial clout. Likewise, some neighborhoods that had already been formally incorporated into Indianapolis (such as Broad Ripple) possess similar influence.

Marion County has nine townships roughly organized into a grid-like, three-by-three pattern. This arrangement can be seen below, with the top being north.
Most of Marion County is in Indiana's 7th congressional district, which is held by Democrat André Carson. Indiana's 5th congressional district, which runs along the northern edge of the county, is held by Republican Susan Brooks. 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 also makes appointments to certain boards and commissions.
