Sidney measured against every US city with 1,000+ residents, computed live from the same Census and FBI data shown throughout this page.
"Safer than" reflects total crime rate from FBI UCR; the others use Census ACS estimates.
National percentiles can mask local variation. Looking only at Montana, Sidney ranks #17 of 39 Montana cities by lowest crime rate - a narrower, more locally useful cut than the national comparison above.
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 Sidney'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 Montana, breaking ties alphabetically. See the methodology page for the full source-to-figure lineage.
