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 Rock Island Arsenal'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.
