According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Fairfield, IA shows violent crime at 140.5 per 100,000 residents and property crime at 486.4 per 100,000.

Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Fairfield reported 13 violent offences in 2024 against a population of 9,251. 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 Fairfield's 140.5 violent-crime rate per 100,000 are Oskaloosa (140.1), Waverly (141.4), Waukee (141.9), Altoona (142.7). 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 199.3 per 100,000 in 2020 to 140.5 in 2024 (-29.5%). The highest observed value was 280.1 in 2022 and the lowest 126.7 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property-offense composition
Larceny-theft is 57.8% of reported property offenses in Fairfield, against a cohort median of 76.8%. The remainder is burglary (10) and motor vehicle theft (9). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Offense mix
Violent offenses are 22.4% of the 58 Part I offenses reported in Fairfield for 2024, against a median of 15.8% across comparable Iowa cities — a gap of 6.6 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 140.5 reported violent offenses per 100,000 residents in 2024, Fairfield ranks 78 of 148 — above 70 of the 147 other Iowa cities whose 2024 submission passes this site’s completeness test. That is -4.0% against the cohort median of 146.3. 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 Fairfield'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 13 reported violent incidents in a population of 9,251. 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.
Across 6.6 Census sq mi, Fairfield logged 6.8 property and 2 violent offenses per square mile in 2024.
Fairfield leans on larceny-theft at 45% of reported offenses, with a moderate mix index of 2,872.
