According to the FBI Uniform Crime Reporting (UCR) Program for 2024, New Castle, DE shows violent crime at 378.2 per 100,000 residents and property crime at 3,530.3 per 100,000. Violent crime runs 7% above the U.S. average. PlainCrime assigns grade D from those rates. Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
New Castle reported 21 violent offences in 2024 against a population of 5,552. At this volume one additional or one fewer report moves the per-100,000 rate noticeably, so the figure is better read as a data point than as a precise measurement, and year-to-year swings here are expected.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 239.9 per 100,000 in 2020 to 378.2 in 2024 (+57.7%). The highest observed value was 561.1 in 2023 and the lowest 239.9 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Comparable rate records
The nearest comparable 2024 records to New Castle's 378.2 violent-crime rate per 100,000 are Harrington (385.8), Millsboro (418.6), Camden (320.8), Newark (309.7). These are same-year agency submissions that pass the same completeness screen, not a claim that the cities have identical conditions. They make the cohort position above checkable against named records instead of a generic state average.
Offense mix
Violent offenses are 9.7% of the 217 Part I offenses reported in New Castle for 2024, against a median of 14.3% across comparable Delaware cities — a gap of 4.6 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.
Position in the state cohort
At 378.2 reported violent offenses per 100,000 residents in 2024, New Castle ranks 17 of 38 — above 21 of the 37 other Delaware cities whose 2024 submission passes this site’s completeness test. That is +28.5% against the cohort median of 294.2. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Property counts dominate New Castle's FBI UCR Table 8 municipal row. Per-100,000 rates use the reporting-year population on that row; cities that fail the completeness test stay out of rate rankings. A citywide figure rarely describes any single neighbourhood inside the municipal boundary.
Based on 21 reported violent incidents in a population of 5,552. At this volume, one additional or one fewer report can shift the rate and letter grade noticeably; small-city crime counts are inherently more volatile year to year than large-city counts, so treat this grade as a data point, not a precise ranking.
Small-city offense counts above are voluntary UCR submissions, not neighbourhood advice. Year-to-year swings can look large when the population base is modest.
