The City of Chicago has a mayor-council form of municipal government. The city’s government is made up of two branches: the executive branch, which is headed by the mayor, and the legislative branch, which is led by the City Council.
The mayor is elected in a city-wide popular vote and serves a term of four years. The mayoral election is held on the last Tuesday in February. The City Council is comprised of 50 aldermen, one from each of Chicago’s 50 wards. The aldermen also serve four-year terms and are elected by popular vote in the ward that they represent. There are no term limits for either the mayor or aldermen.
