Is ZIP code 51246 safe? Honest data snapshot

ZIP code 51246 sits within Lyon County, IA. 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.

Lyon County reported a violent-crime rate of 8 per 100,000 residents and a property-crime rate of 151 per 100,000 in 2024, drawing on county-level agency submissions.

Based on just 1 reported violent incidents across a county population of 11,934, 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 51246 is the largest ZIP in Lyon County by population, 4,007 residents (#1 of 8 county ZIPs), across 161.11 square miles (25/sq mi). For a full breakdown of Lyon County's crime categories and year-over-year trend, see the Lyon County crime page linked below.
