How does Longmont compare to other US cities?

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

Household income 71% higher than other cities
Home value 87% pricier than other cities
Median rent 85% pricier than other cities
Safety 15% safer 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 Longmont against every qualifying US city; each in-state rank narrows that to Colorado only. Full formula and direction notes: methodology.
