According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Mercer, PA shows violent crime at 52.2 per 100,000 residents and property crime at 1,512.8 per 100,000.

Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Mercer reported 1 violent offences in 2024 against a population of 1,917. 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 107.2 per 100,000 in 2020 to 52.2 in 2024 (-51.4%). The highest observed value was 107.2 in 2020 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.
Comparable rate records
The nearest comparable 2024 records to Mercer's 52.2 violent-crime rate per 100,000 are Amity Township (52.1), East Whiteland Township (52.3), West Lampeter Township (52.0), Foster Township, McKean County (51.8). 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 3.3% of the 30 Part I offenses reported in Mercer for 2024, against a median of 10.0% across comparable Pennsylvania cities — a gap of 6.7 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 96.6% of reported property offenses in Mercer, against a cohort median of 85.8%. The remainder is burglary (1) and motor vehicle theft (0). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Position in the state cohort
At 52.2 reported violent offenses per 100,000 residents in 2024, Mercer ranks 473 of 838 — above 365 of the 837 other Pennsylvania cities whose 2024 submission passes this site’s completeness test. That is -21.1% 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.
Property counts dominate Mercer'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 1 reported violent incidents in a population of 1,917. 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.
On a small municipal row, small denominators make rates sensitive to a handful of incidents. Figures are reported totals, not neighbourhood advice.
