Most Dense — Illinois
The most densely populated cities in Illinois pack the most residents per square mile, creating vibrant urban environments with walkable neighborhoods and extensive public transit. Berwyn leads with 14,330 people per square mile.
High population density is often associated with better access to public transportation, more walkable streets, and a wider variety of restaurants, shops, and entertainment options within close proximity. These cities tend to have lower car ownership rates and shorter commute distances.
Dense cities face unique challenges including higher housing costs, limited parking, and potential overcrowding in public spaces. However, they also tend to have lower per-capita carbon footprints due to shared infrastructure and reduced driving.
