Wonder Lake, up 33.4% from July 2020 to July 2024 among places of 5,000+, to 5,296 residents.
Which Illinois city added the most people?
Yorkville, which gained 4,221 residents from July 2020 to July 2024.
How many Illinois cities are shrinking?
218 of 330 places of 5,000+ had the same or fewer residents in July 2024 than in July 2020.
Why use places of 5,000 or more?
Small towns can swing by double-digit percentages from a few new homes, and Census estimates for them carry more uncertainty. The 5,000 floor keeps the ranking to places where a percentage means something.
