What is the Population of Chicago? 

The most recent calculation of Chicago’s population is 2.71 million residents spanning across the city’s 234 million square miles. The number of people in Chicago help the city rank as the:

  • #1 most populous city in the Midwest
  • #3 most populous city in the United States
  • #5 most populous city in North America 

The city’s popularity is attributed to many factors. Built on the shores of Lake Michigan, Chicago provides its residents with a harmonious balance of city amenities and natural elements, allowing people to spend an afternoon at the beach and then dinner at a fine dining restaurant. Chicago also offers a wealth of culture, entertainment, education, and career opportunities, attracting a large population with a wide variety of interests and passions. 

How the Chicago Population Has Grown 

Chicago was incorporated in 1837 with a founding population of 4,000 residents. Modern innovations such as a dedicated railroad line and telegraph access increased the Chicago population density over the next several decades, and by 1854, the number of people in Chicago soared over 30,000. 

By the time of the Great Chicago Fire in 1871, there were over 320,000 people living in Chicago, but the disaster ravaged a third of the city and left an estimated 100,000 people homeless. After a significant building effort, the city slowly began to recover and revive interest in commerce and tourism. 

Chicago’s population density saw steady inclines until the 1950s and 60s when suburban areas began drawing families away from the city. Even still, the Windy City has continued to be a midwestern beacon for entertainment and opportunity, drawing over 50 million visitors a year.
