Small-count caution
Groton Town reported 26 violent offences in 2024 against a population of 27,927. 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.
Comparable rate records
The nearest comparable 2024 records to Groton Town's 93.1 violent-crime rate per 100,000 are Berlin (92.6), East Hartford (89.0), Windsor Locks (87.9), East Haven (98.4). 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 93.1 reported violent offenses per 100,000 residents in 2024, Groton Town ranks 23 of 94 — above 71 of the 93 other Connecticut cities whose 2024 submission passes this site’s completeness test. That is +60.2% against the cohort median of 58.1. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 76.2 per 100,000 in 2020 to 93.1 in 2024 (+22.3%). The highest observed value was 139.1 in 2021 and the lowest 73.4 in 2022. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Offense mix
Violent offenses are 8.6% of the 302 Part I offenses reported in Groton Town for 2024, against a median of 4.7% across comparable Connecticut cities — a gap of 3.9 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 Groton Town'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 26 reported violent incidents in a population of 27,927. 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.
Mid-size municipal totals above are reported offenses, not safety advice for any single block. Reporting completeness still varies by year and agency.
