Is ZIP code 83666 safe? Honest data snapshot
ZIP code 83666 sits within Boise County, ID. 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.
Boise County reported a violent-crime rate of 289 per 100,000 residents and a property-crime rate of 171 per 100,000 in 2024, drawing on county-level agency submissions.
Based on just 22 reported violent incidents across a county population of 7,610, 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 83666 carries a Census-reported population of 41, ranking #5 of 6 ZIPs in Boise County, spread across 10.2 square miles (about 4 people per square mile). For a full breakdown of Boise County's crime categories and year-over-year trend, see the Boise County crime page linked below.
