ZIP 18351 settlement vs Northampton County
ZIP 18351 itself is about 1,836 people per Census sq mi across 0.3 sq mi (606 residents), a postal settlement fact independent of the county UCR proxy.
ZIP 18351 is about 0.2% of the county reporting population (606 of 312,951), so most of the denominator and submitted incidents sit outside this postal code.
Northampton County's 2024 UCR book concentrates in aggravated assault (100% of 1 offenses; mix index 10,000). ZIP 18351 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.
