Chicago, the largest city in Illinois and the Midwest, stands proudly along the western shore of Lake Michigan. Founded by Jean Baptiste Point du Sable around 1780, the city officially became a town in 1833 and a city in 1837. Today, it is home to over 2.7 million residents, making it the third-most populous city in the United States.

The Chicago metropolitan area stretches across more than 9.4 million people, ranking third in the nation and highlighting the city’s significance as a cultural and economic hub. Chicago is famous for iconic attractions such as the Art Institute of Chicago, Navy Pier, Wrigley Field, and the historic “L” train system. The city’s nickname, “The Windy City,” reflects both its breezy lakeshore and its vibrant public life.

Governed by a mayor–council system, Chicago is currently led by Mayor Brandon Johnson. The city spans 234.53 square miles, with a diverse population that thrives in its mix of urban density and lakeside charm. With a metropolitan GDP of over $919 billion in 2024, Chicago is not only a cultural icon but also a major economic powerhouse in the United States.
