How does Waterloo compare to other US cities?

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

Household income 29% higher than other cities
Home value 27% pricier than other cities
Median rent 24% pricier than other cities
Safety 17% 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 Iowa alone, Waterloo ranks #131 of 141 Iowa 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 Waterloo'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 Iowa, breaking ties alphabetically. See the methodology page for the full source-to-figure lineage.
