National percentiles can mask local variation. Looking only at Maine, Belfast ranks #19 of 73 Maine cities by lowest crime rate - a narrower, more locally useful cut than the national comparison above.
Each percentile compares Belfast against every qualifying US city; each in-state rank narrows that to Maine only. Full formula and direction notes: methodology.
Maine-relative analysis
Among the 154 Maine cities PlainCities tracks with reported bachelor's degree or higher data, Belfast ranks #27 - the 82nd percentile within the state. This is a different, narrower cut than the nationwide percentiles above: it compares Belfast 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 Maine only, not a livability score. See the methodology for the source and calculation.
