Here's how Northfield 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 Minnesota, Northfield ranks #160 of 229 Minnesota cities by lowest crime rate - a narrower, more locally useful cut than the national comparison above.
Each percentile compares Northfield against every qualifying US city; each in-state rank narrows that to Minnesota only. Full formula and direction notes: methodology.
Minnesota-relative analysis
Among the 784 Minnesota cities PlainCities tracks with reported bachelor's degree or higher data, Northfield ranks #53 - the 93rd percentile within the state. This is a different, narrower cut than the nationwide percentiles above: it compares Northfield 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 Minnesota only, not a livability score. See the methodology for the source and calculation.
