How does Clarendon Hills compare to other US cities?

Where Clarendon Hills sits among all US cities (population 1,000+) on each measure, computed live from Census and FBI data.

Household income 89% higher than other cities
Home value 89% pricier than other cities
Median rent 72% pricier than other cities
Safety 88% safer than other cities

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

A national percentile can hide a lot of local variation: narrowed to Illinois alone, Clarendon Hills ranks #96 of 455 Illinois cities by lowest crime rate - a different, more locally useful comparison than stacking it against the entire country.

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 Clarendon Hills'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.
