Methodology: How We Determined The Most Expensive Places To Live In The Prairie State For 2026

The two most important things to think about when it comes to being able to afford a city in Illinois are how much money you make and how much you have to spend to live there.

You need to understand your costs in the context of how much money you make.

For example, if the median household earns $100,000 and spends $40,000 on housing, it’s actually cheaper to live there than a place with a median income of $50,000 and housing costs of $21,000. You might spend more on housing, but you have more money overall to play with.

With that example in mind, we derived several statistics from the latest Census American Community Survey 2020-2024 around incomes and costs. They are:

  • Overall Cost Of Living Index
  • Median Home Price / Median Income (lower is better)
  • Median Income / Median Rent (Higher is better)
  • Median Home Price

You can then compare these metrics in each of the places in Illinois to figure out which is the most expensive.

You are left with a “Cost of Living Index” by taking the average rank of each of these metrics for each city.

So we used that cost of living index to rank all of the 330 places in Illinois that have more than 5,000 people.

The place with the highest cost of living in Illinois according to the data is Glencoe. We updated this article for 2026. This article is our eleventh time ranking the most expensive places to live in Illinois.
