According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Walnut, CA shows violent crime at 127.3 per 100,000 residents and property crime at 1,891.2 per 100,000.

Position in the state cohort
At 127.3 reported violent offenses per 100,000 residents in 2024, Walnut ranks 399 of 458 — above 59 of the 457 other California cities whose 2024 submission passes this site’s completeness test. That is -61.8% against the cohort median of 333.1. 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 Walnut's 127.3 violent-crime rate per 100,000 are Laguna Niguel (126.7), Camarillo (128.8), Simi Valley (129.1), Agoura Hills (124.8). 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 44.4% of reported property offenses in Walnut, against a cohort median of 69.5%. The remainder is burglary (243) and motor vehicle theft (38). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Offense mix
Violent offenses are 6.3% of the 539 Part I offenses reported in Walnut for 2024, against a median of 17.1% across comparable California cities — a gap of 10.8 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.
2020–2024 direction
Across 4 comparable reporting years, the rate moved from 127.8 per 100,000 in 2020 to 127.3 in 2024 (-0.3%). The highest observed value was 160.0 in 2023 and the lowest 127.3 in 2024. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Walnut'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.
