Richest Cities in Illinois

Illinois is the preemptive state of the Midwestern United States and is one of the most important States in the Union. It has the fifth largest economy and is sixth in terms of population. While most people only think of Chicago when talking about Illinois, there are countless cities that are well off and can provide their citizens with a good income. We compiled a list of the richest cities in Illinois in case you are interested:


Naperville is located in the West of Chicago and can be considered a suburb of it, despite the fact that there are 150 thousand people living there. Many of the residents commute to downtown Chicago or some of the other satellite cities surrounding it, but there are plenty of jobs to be found in Naperville. Nokia has a large office there, and BP, Nalco, and Bell labs also have offices there, among many other companies. Like cities in America, retail, restaurants, and shopping centers provide a lot of employment and wealth to the community. The largest employer is Edward Hospital, which has more than 4500 employees.

St. Louis

Including St. Louis in a list of the richest cities in Illinois is kind of cheating, but it is a bi-state city and has hundreds of thousands of residents in the State of Illinois. The city has fallen on hard times in recent years, but it remains a large American metropolis and that means that there is a lot of money being made here. There are 10 Fortune 500 companies in St. Louis including Emerson Electric, Express Scripts, Reinsurance Group of America, and Monsanto. While the manufacturing industry is not what it used to be, there is a sizable and growing biotechnology industry. While this cannot replace automobile manufacturing, it does provide good-paying jobs with a career path to the citizens of St. Louis.


Chicago is the third largest city in the US and the most populous city in the Midwestern United States. Due to its large size, strategic location, and historical importance, it dominates the State of Illinois and the entire region. Historically, the city has been a major world financial center, with the Federal Reserve, Chicago Stock Exchange, CBOE, the Mercantile Exchange, Chase bank, and many others being located here. Besides finance, there is a great tech ecosystem in Chicago, with many large corporations and startups being based here. There is also a very large and successful convention destination and a popular tourist destination, both of which bring millions of visitors every year.
