Is ZIP code 81146 safe? Honest data snapshot
ZIP code 81146 sits within Alamosa County, CO. 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.
Alamosa County reported a violent-crime rate of 67 per 100,000 residents and a property-crime rate of 702 per 100,000 in 2024, drawing on county-level agency submissions.
Based on just 11 reported violent incidents across a county population of 16,376, 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 81146 carries a Census-reported population of 820, ranking #2 of 3 ZIPs in Alamosa County, spread across 279.86 square miles (about 3 people per square mile). For a full breakdown of Alamosa County's crime categories and year-over-year trend, see the Alamosa County crime page linked below.
