Is ZIP code 37779 safe? Honest data snapshot
ZIP code 37779 sits within Union County, TN. 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.
Union County reported a violent-crime rate of 91 per 100,000 residents and a property-crime rate of 732 per 100,000 in 2024, drawing on county-level agency submissions.
Based on just 18 reported violent incidents across a county population of 19,802, 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 37779 carries a Census-reported population of 3,376, ranking #2 of 3 ZIPs in Union County, spread across 34.56 square miles (about 98 people per square mile). For a full breakdown of Union County's crime categories and year-over-year trend, see the Union County crime page linked below.
