Offense mix
Violent offenses are 35.1% of the 111 Part I offenses reported in Arnold for 2024, against a median of 10.0% across comparable Pennsylvania cities — a gap of 25.1 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 839.8 reported violent offenses per 100,000 residents in 2024, Arnold ranks 10 of 838 — above 828 of the 837 other Pennsylvania cities whose 2024 submission passes this site’s completeness test. That is +1185.7% against the cohort median of 65.3. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Comparable rate records
The nearest comparable 2024 records to Arnold's 839.8 violent-crime rate per 100,000 are Steelton (838.3), Bradford (843.3), Plymouth (834.1), Darby (831.3). 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.
Property-offense composition
Larceny-theft is 63.9% of reported property offenses in Arnold, against a cohort median of 85.9%. The remainder is burglary (19) and motor vehicle theft (7). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 750.5 per 100,000 in 2020 to 839.8 in 2024 (+11.9%). The highest observed value was 839.8 in 2024 and the lowest 0.0 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Arnold'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.
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.
