Crime data uses FBI UCR; climate uses NOAA Climate Normals; school counts come from NCES Common Core of Data; permits use the Census Building Permits Survey (BPS). See our methodology page for the full ETL pipeline and OMB / FIPS join keys.

Where Erin sits among all US cities (population 1,000+) on each measure, computed live from Census and FBI data.
"Safer than" reflects total crime rate from FBI UCR; the others use Census ACS estimates.
A national percentile can hide a lot of local variation: narrowed to Tennessee alone, Erin ranks #7 of 174 Tennessee cities by lowest crime rate - a different, more locally useful comparison than stacking it against the entire country.
Each percentile compares Erin against every qualifying US city; each in-state rank narrows that to Tennessee only. Full formula and direction notes: methodology.
Tennessee-relative analysis
Among the 482 Tennessee cities PlainCities tracks with reported median gross rent data, Erin ranks #341 - the 0th percentile within the state. This is a different, narrower cut than the nationwide percentiles above: it compares Erin 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 Tennessee only, not a livability score. See the methodology for the source and calculation.
