Is ZIP code 61770 safe? Honest data snapshot

ZIP code 61770 sits within McLean County, IL. 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.

McLean County reported a violent-crime rate of 15 per 100,000 residents and a property-crime rate of 53 per 100,000 in 2024, drawing on county-level agency submissions.

Based on just 25 reported violent incidents across a county population of 170,954, 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 61770 carries a Census-reported population of 1,146, ranking #15 of 24 ZIPs in McLean County, spread across 60.46 square miles (about 19 people per square mile). For a full breakdown of McLean County's crime categories and year-over-year trend, see the McLean County crime page linked below.
