Norwalk, IA carries a PlainCrime A safety grade with violent crime 69% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Norwalk, IA shows violent crime at 109.1 per 100,000 residents and property crime at 179.6 per 100,000. Violent crime runs 69% below the U.S. average. PlainCrime assigns grade A from those rates. Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 48.7 per 100,000 in 2020 to 109.1 in 2024 (+123.8%). The highest observed value was 109.1 in 2024 and the lowest 48.7 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Small-count caution
Norwalk reported 17 violent offences in 2024 against a population of 15,588. 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.
Offense mix
Violent offenses are 37.8% of the 45 Part I offenses reported in Norwalk for 2024, against a median of 15.8% across comparable Iowa cities — a gap of 22.0 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.
Comparable rate records
The nearest comparable 2024 records to Norwalk's 109.1 violent-crime rate per 100,000 are Pella (109.7), Gowrie (107.8), West Branch (105.6), Lansing (105.2). 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.
Property-offense composition
Larceny-theft is 100.0% of reported property offenses in Norwalk, against a cohort median of 76.1%. The remainder is burglary (0) and motor vehicle theft (0). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Position in the state cohort
At 109.1 reported violent offenses per 100,000 residents in 2024, Norwalk ranks 93 of 148 — above 55 of the 147 other Iowa cities whose 2024 submission passes this site’s completeness test. That is -25.5% 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 Norwalk'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 17 reported violent incidents in a population of 15,588. 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.
