How does Lemont compare to other US cities?

Lemont measured against every US city with 1,000+ residents, computed live from the same Census and FBI data shown throughout this page.

Household income 89% higher than other cities
Home value 81% pricier than other cities
Median rent 72% pricier than other cities

"Safer than" reflects total crime rate from FBI UCR; the others use Census ACS estimates.

How we calculate these percentiles & ranks

Each percentile compares Lemont against every qualifying US city; each in-state rank narrows that to Illinois only. Full formula and direction notes: methodology.
