Is ZIP code 52738 safe? Honest data snapshot

ZIP code 52738 sits within Louisa 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.

Louisa County reported a violent-crime rate of 166 per 100,000 residents and a property-crime rate of 332 per 100,000 in 2024, drawing on county-level agency submissions.

Based on just 18 reported violent incidents across a county population of 10,837, 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.
