ZIP 83451 settlement vs Madison County

ZIP 83451 itself is about 63 people per Census sq mi across 16.6 sq mi (1,038 residents), a postal settlement fact independent of the county UCR proxy.

ZIP 83451 is about 2% of the county reporting population (1,038 of 52,913), so most of the denominator and submitted incidents sit outside this postal code.

Madison County's 2024 UCR book concentrates in larceny-theft (54% of 59 offenses; mix index 4,163). ZIP 83451 inherits that county mix, not a postal-native split.

Settlement lines use Census ZCTA figures only; incomplete county agency coverage blocks any UCR mix or rate desk for this ZIP.
