Small-count caution
St. Ignatius reported 4 violent offences in 2024 against a population of 836. 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 St. Ignatius's 478.5 violent-crime rate per 100,000 are Wolf Point (484.1), Hot Springs (471.7), Sidney (464.3), Deer Lodge (461.7). 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 4.9% of the 82 Part I offenses reported in St. Ignatius for 2024, against a median of 19.5% across comparable Montana cities — a gap of 14.6 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 478.5 reported violent offenses per 100,000 residents in 2024, St. Ignatius ranks 17 of 44 — above 27 of the 43 other Montana cities whose 2024 submission passes this site’s completeness test. That is +40.2% against the cohort median of 341.3. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Property-offense composition
Larceny-theft is 76.9% of reported property offenses in St. Ignatius, against a cohort median of 85.6%. The remainder is burglary (3) and motor vehicle theft (15). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate St. Ignatius'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 4 reported violent incidents in a population of 836. 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.
