2024 reported record
Of the 3,595 Part I offences New Castle County reported for 2024, 19.2% were violent. Aggravated assault leads the violent categories at 577, and larceny-theft leads the property categories at 1,744, against a population of 570,719. Delaware has too few counties with a comparable 2024 submission to place this record against an in-state cohort, so it is reported on its own terms.
On a very large county row, county figures aggregate every participating agency inside the county. Participation is voluntary. Per-100,000 rates use a separately matched 2020 U.S. Census county population, never a Table 10 field; unmatched counties stay count-only. A large county line encloses very different communities.
