How does Twin Rocks compare to other US cities?

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

Median rent 23% pricier than other cities

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

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 Twin Rocks'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 Pennsylvania, breaking ties alphabetically. See the methodology page for the full source-to-figure lineage.
