Offense mix
Violent offenses are 40.4% of the 52 Part I offenses reported in St. Johns for 2024, against a median of 14.3% across comparable Arizona cities — a gap of 26.1 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.
Small-count caution
St. Johns reported 21 violent offences in 2024 against a population of 3,343. 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.
Position in the state cohort
At 628.2 reported violent offenses per 100,000 residents in 2024, St. Johns ranks 7 of 64 — above 57 of the 63 other Arizona cities whose 2024 submission passes this site’s completeness test. That is +146.7% against the cohort median of 254.7. 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 St. Johns's 628.2 violent-crime rate per 100,000 are Williams (619.9), Tucson (588.8), Page (548.8), Show Low (737.4). 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 455.3 per 100,000 in 2020 to 628.2 in 2024 (+38.0%). The highest observed value was 628.2 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-offense composition
Larceny-theft is 51.6% of reported property offenses in St. Johns, against a cohort median of 77.9%. The remainder is burglary (12) and motor vehicle theft (3). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate St. Johns'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 21 reported violent incidents in a population of 3,343. 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.
