How does Island Lake compare to other US cities?

Here's how Island Lake stacks up against the full field of US cities (population 1,000+), computed live from Census and FBI data.

Household income 77% higher than other cities
Home value 54% pricier than other cities
Median rent 72% pricier than other cities
Safety 81% 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, Island Lake ranks #131 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

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