Is ZIP code 57454 safe? Honest data snapshot
ZIP code 57454 sits within Marshall County, SD. The figures below are the county's own FBI UCR numbers for 2024, the most accurate available statistic for this location, not a ZIP-specific calculation.
Marshall County reported a violent-crime rate of 70 per 100,000 residents and a property-crime rate of 209 per 100,000 in 2024, drawing on county-level agency submissions.
Based on just 3 reported violent incidents across a county population of 4,306, this count is too low to support a reliable per-100K rate comparison. It may reflect a genuinely low-crime county, or it may reflect incomplete agency-level reporting to the FBI UCR Program for this county and year, small county-level counts are common in FBI Table 10 and should be treated as a data point, not a precise safety ranking.
ZIP 57454 carries a Census-reported population of 726, ranking #3 of 6 ZIPs in Marshall County, spread across 151.32 square miles (about 5 people per square mile). For a full breakdown of Marshall County's crime categories and year-over-year trend, see the Marshall County crime page linked below.
