Is ZIP code 57735 safe? Honest data snapshot

ZIP code 57735 sits within Fall River 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.

Fall River County reported a violent-crime rate of 29 per 100,000 residents and a property-crime rate of 86 per 100,000 in 2024, drawing on county-level agency submissions.

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.
