ZIP 40118 settlement vs Jefferson County

ZIP 40118 itself is about 675 people per Census sq mi across 15 sq mi (10,141 residents), a postal settlement fact independent of the county UCR proxy.

ZIP 40118 is about 1.3% of the county reporting population (10,141 of 782,969), so most of the denominator and submitted incidents sit outside this postal code.

Jefferson County's 2024 UCR book concentrates in aggravated assault (100% of 2 offenses; mix index 10,000). ZIP 40118 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.
