According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Mountain Brook, AL shows violent crime at 65.2 per 100,000 residents and property crime at 772.6 per 100,000.

Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Mountain Brook reported 14 violent offences in 2024 against a population of 21,486. 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 Mountain Brook's 65.2 violent-crime rate per 100,000 are Tuscumbia (65.2), Hanceville (59.5), Helena (71.2), Triana (59.0). 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 65.2 reported violent offenses per 100,000 residents in 2024, Mountain Brook ranks 219 of 263 — above 44 of the 262 other Alabama cities whose 2024 submission passes this site’s completeness test. That is -70.0% against the cohort median of 217.1. 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 7.8% of the 180 Part I offenses reported in Mountain Brook for 2024, against a median of 13.9% across comparable Alabama cities — a gap of 6.1 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.
Property-offense composition
Larceny-theft is 82.5% of reported property offenses in Mountain Brook, against a cohort median of 74.2%. The remainder is burglary (22) and motor vehicle theft (7). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Mountain Brook'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 14 reported violent incidents in a population of 21,486. 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.
