Small-count caution
Mount Joy reported 2 violent offences in 2024 against a population of 8,349. 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 95.5 per 100,000 in 2020 to 24.0 in 2024 (-74.9%). The highest observed value was 95.5 in 2020 and the lowest 12.0 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 Mount Joy's 24.0 violent-crime rate per 100,000 are Murrysville (24.2), Larksville (23.5), Upper St. Clair Township (24.5), New Holland (23.3). 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.
Position in the state cohort
At 24.0 reported violent offenses per 100,000 residents in 2024, Mount Joy ranks 587 of 838 — above 251 of the 837 other Pennsylvania cities whose 2024 submission passes this site’s completeness test. That is -63.8% against the cohort median of 66.1. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Offense mix
Violent offenses are 5.6% of the 36 Part I offenses reported in Mount Joy for 2024, against a median of 10.0% across comparable Pennsylvania cities — a gap of 4.4 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 Mount Joy'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 2 reported violent incidents in a population of 8,349. 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.
