How does Mount Prospect compare to other US cities?

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

Household income 80% higher than other cities
Home value 75% pricier than other cities
Median rent 72% pricier than other cities
Safety 65% safer than other cities

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

National percentiles can mask local variation. Looking only at Illinois, Mount Prospect ranks #240 of 455 Illinois cities by lowest crime rate - a narrower, more locally useful cut than the national comparison above.

How we calculate these percentiles & ranks

For each metric we count every US city with population 1,000+ and a non-null value, then compute what share of them fall below Mount Prospect's value: round(cities-below ÷ total × 100). Safety is inverted (percentile = share of cities with a higher crime rate) so a higher number always means safer. The in-state rank narrows that same crime-rate comparison to only the cities PlainCities tracks in Illinois, breaking ties alphabetically. See the methodology page for the full source-to-figure lineage.
