Ennis - the verdict
Ennis ranks in the 37th percentile for household income and the 87th percentile for safety nationally, out of every US city with at least 1,000 residents. Source: Census ACS + FBI UCR.
Population, income, and housing-cost figures come from the U.S. Census Bureau American Community Survey 5-year estimates (B-series tables). 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.

Ennis 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.
A national percentile can hide a lot of local variation: narrowed to Montana alone, Ennis ranks #4 of 39 Montana cities by lowest crime rate - a different, more locally useful comparison than stacking it against the entire country.
Each percentile compares Ennis against every qualifying US city; each in-state rank narrows that to Montana only. Full formula and direction notes: methodology.
Montana-relative analysis
Among the 279 Montana cities PlainCities tracks with reported median home value data, Ennis ranks #59 - the 79th percentile within the state. This is a different, narrower cut than the nationwide percentiles above: it compares Ennis 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 Montana only, not a livability score. See the methodology for the source and calculation.
