Here's how Loudon 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.
Zoom in to just New Hampshire and the picture shifts: Loudon ranks #5 of 53 New Hampshire cities by lowest crime rate, a different read than the national percentile above.
For each metric we count every US city with population 1,000+ and a non-null value, then compute what share of them fall below Loudon's value: round(cities-below ÷ total × 100). Safety is inverted (percentile = share of cities with a higher crime rate) so a higher number always means safer. The in-state rank narrows that same crime-rate comparison to only the cities PlainCities tracks in New Hampshire, breaking ties alphabetically. See the methodology page for the full source-to-figure lineage.
