The City of Chicago is a municipality located in Cook County, Illinois. It has over 2.7 million people and covers more than 227 square miles, with the city limits stretching as far as 25 miles from downtown.

The Chicago government employs close to 20,000 people and has been led by Mayor Lori E. Lightfoot since 2019. A few noteworthy facts about Chicago’s government are that it operates on an annual budget exceeding $8 billion U.S., pays out pensions for nearly 98% of its retired employees, and oversees more than 130 public schools with approximately 400 campuses across the greater metropolitan area.

According to the American Community Survey, the population of Chicago was 2,695,598, with a median age of 34.8 years. Also, 51.6% of the population is female. The 2020 Census shows that 21.5% of the population lives below the poverty line, and 59.4% reported having at least some college education or post-secondary schooling.

These numbers are all important facts to note when you are trying to understand the composition of the Chicago government. For example, if most residents are female and college-educated, more women may be in high-ranking positions than in other cities in Cook County and the surrounding area.

Tourism and Government Jobs

Chicago is one of the largest tourist magnets and employment hubs nationwide, attracting locals and foreigners alike. The city’s local government has a huge role in the smooth functioning and running of the locality.

Initially, Chicago was a small trading center settled in the 1770s by Jean Baptiste Point de Sable. In March 1837, it was incorporated as a city. What was once a small center on Lake Michigan shore quickly began developing into the metropolis today.

As for the government, Chicago is divided into ‘ward’ or municipal legislative districts, each represented by an Alderman in the city council. Originally, the city had six wards, which were established in 1837 as per the charter then.
Now, Chicago has 50 wards, and the Illinois Constitution authorizes the local government to perform certain acts and any function about its affairs. These authorization powers are held by the city council, the city treasurer, the city clerk, and the mayor.

The City of Chicago Governmental Structure and Departments

The state legislature and home rule provisions grant the Chicago city legislative powers in compliance with the Illinois constitution. As a result, the City Council has wide power over the city’s government and affairs, including the authority to regulate for the protection of public health, safety, morals, and interests.

To put it simply, Chicago has a mayor-council government type. In this type of government, the council members and the mayor work together in balancing things along with passing the city budget, overseeing city departments, drafting legislations, and then enforcing them. The mayor must preside at council meetings as the head of the city.

Under the Illinois Constitution, the city of Chicago holds the position of a home rule governmental unit. Therefore, the authorities in the city have the power to perform jobs and functions.

Here are the notable positions in the city of Chicago government:


Lori E Lightfoot is the mayor of Chicago, responsible for managing and administering different city government departments. In Chicago city, the mayor serves for four years.

The mayor’s job is to submit recommendations and proposals to the Chicago city council. They also must enforce the ordinances and legislations unanimously agreed upon by the council members.

More importantly, the mayor submits the annual budget of the city and appoints different members of the government, such as:

  • City officers
  • Department commissioners
  • Department directors
  • City board members

In a city council meeting, the mayor acts as the presiding officer. If the mayor is not present, President Pro Tempore takes their place. President Pro Tempore is also a part of the council and must be elected by the members.

The mayor can also submit recommendations to the council on the city departments’ behalf or their own. Then, the city council votes on these legislative matters.

Even though the mayor is a part of the Chicago city council, they cannot vote on the issues discussed in the meetings, except in some exceptional cases.

For example, if the city council’s vote ends up in a tie, the mayor may be asked to vote. Meanwhile, President Pro Tempore is authorized to vote on every discussion in the Chicago city council meeting.

City Clerk

The city clerk keeps a record of the council and the city documents. The city clerk also maintains the city’s corporate seal and publishes the city council’s legislative record in the Journal of Proceedings.

Depending on the directions given by the municipal law or state, the city clerk has to record the council’s actions in the relevant pamphlets and documents. Thus, the city clerk also serves as an official witness to the different meetings of the Chicago city council.

City Treasurer

The city treasurer monitors and manages the investments and cash flow in the city. The treasurer also manages the teacher’s pension and employee pension funds.

Moreover, the treasurer is also involved in managing several programs that help economically develop the city. Every year, the treasurer must file a report with the city council.

The report summarizes how the city’s investments went, how much money was received, where it was invested, and how it was dispersed.


Alderpersons are elected for a four-year period during which they represent their designated district, called a ward.

The city of Chicago holds elections for Alderman selection in February. These elections, held on the last Tuesday of the month, determine who will represent the ward for the next four years, based on the ward’s voters.

If there is no chosen candidate, the city holds a run-off election between the candidates getting the highest votes on the first Tuesday of April that year due to the lack of sufficient vote casts.

A ward’s Alderman is responsible for voicing the concerns of the locality in the council. They serve as intermediaries between the council and the ward.

The Alderman also must recommend and support legislation for different wards and the city.

What are the Political Districts in the City of Chicago?

The political districts, or wards, in the city of Chicago are municipal regions that an elected Alderman represents. Currently, there are 50 political districts or wards in the city. You can find the ward your house falls in by checking using your street address on the city’s website.

All you must do is type your home or work address, and the search result will show you your ward and the Alderman who represents it. You can also check the Alderman responsible for your ward and contact them by visiting the Chicago City Clerk website.
