ZIP 03233 settlement vs Merrimack County
ZIP 03233 itself is about 475 people per Census sq mi across 0.4 sq mi (209 residents), a postal settlement fact independent of the county UCR proxy.
ZIP 03233 is about 0.1% of the county reporting population (209 of 153,808), so most of the denominator and submitted incidents sit outside this postal code.
Merrimack County's 2024 UCR book concentrates in rape (67% of 3 offenses; mix index 5,556). ZIP 03233 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.
