Offense mix
Violent offenses are 54.5% of the 235 Part I offenses reported in Nassau County for 2024, against a median of 20.7% across comparable Florida counties — a gap of 33.7 points. Offense mix is shaped by which agencies report and how incidents are classified as well as by the underlying offenses, so it describes the reported record rather than a settled difference in conditions.
Property-offense composition
Larceny-theft is 50.5% of reported property offenses in Nassau County, against a cohort median of 77.2%. The remainder is burglary (43) and motor vehicle theft (10). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
2020–2024 direction
Across 4 comparable reporting years, the rate moved from 168.2 per 100,000 in 2020 to 141.7 in 2024 (-15.8%). The highest observed value was 173.8 in 2022 and the lowest 138.3 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 141.7 reported violent offenses per 100,000 residents in 2024, Nassau County ranks 22 of 37 — above 15 of the 36 other Florida counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -9.7% against the cohort median of 156.9. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
On a 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.
