Here's how Belmont stacks up against the full field of US cities (population 1,000+), computed live from Census and FBI data.
"Safer than" reflects total crime rate from FBI UCR; the others use Census ACS estimates.
National percentiles can mask local variation. Looking only at Massachusetts, Belmont ranks #60 of 149 Massachusetts cities by lowest crime rate - a narrower, more locally useful cut than the national comparison above.
Each percentile compares Belmont against every qualifying US city; each in-state rank narrows that to Massachusetts only. Full formula and direction notes: methodology.
Massachusetts-relative analysis
Among the 247 Massachusetts cities PlainCities tracks with reported bachelor's degree or higher data, Belmont ranks #11 - the 95th percentile within the state. This is a different, narrower cut than the nationwide percentiles above: it compares Belmont only against its own state's cities, not the full US field.
Ranked by raw value (highest first); a higher rank is not automatically "better" for every measure, see each metric's own context above. This is a comparison within Massachusetts only, not a livability score. See the methodology for the source and calculation.
