How this was calculated
The area is a 15-minute driving isochrone generated from downtown Chicago (41.8781, -87.6298). Population and demographics are aggregated from every U.S. Census block group centroid falling inside that polygon, using ACS 2024 5-year estimates. Income, home value, age, and poverty figures are population-weighted averages across those block groups, so they approximate rather than exactly reproduce a single official median.
