According to the FBI Uniform Crime Reporting (UCR) Program for 2024, New Castle, CO shows violent crime at 123.7 per 100,000 residents and property crime at 680.3 per 100,000.

Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
New Castle reported 6 violent offences in 2024 against a population of 4,851. 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 75.6 per 100,000 in 2020 to 123.7 in 2024 (+63.5%). The highest observed value was 123.7 in 2024 and the lowest 59.9 in 2021. 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 123.7 violent-crime rate per 100,000 are Golden (123.8), Hudson (124.5), Meeker (126.7), Crested Butte (120.5). 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.
Position in the state cohort
At 123.7 reported violent offenses per 100,000 residents in 2024, New Castle ranks 92 of 134 — above 42 of the 133 other Colorado cities whose 2024 submission passes this site’s completeness test. That is -39.0% against the cohort median of 202.8. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Property-offense composition
Larceny-theft is 60.6% of reported property offenses in New Castle, against a cohort median of 76.9%. The remainder is burglary (8) and motor vehicle theft (5). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Offense mix
Violent offenses are 15.4% of the 39 Part I offenses reported in New Castle for 2024, against a median of 11.7% across comparable Colorado cities — a gap of 3.7 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 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 6 reported violent incidents in a population of 4,851. 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.
