Colorado Risk Spotlight: the highest- and lowest-risk counties (August 2026)
Published 2026-08-10
Every county in Colorado carries a different mix of natural-hazard, road-safety and crime risk. RiskIndex scores all of them on a single 0–100 composite scale (higher = riskier) built entirely from official U.S. government data — FEMA, NHTSA and the FBI. Here's how Colorado's counties stack up this month.
The 5 highest-risk counties in Colorado
| # | County | Composite | Grade |
|---|---|---|---|
| 1 | Pueblo County | 79.9 | D |
| 2 | Weld County | 75.7 | D |
| 3 | Denver County | 73.7 | D |
| 4 | El Paso County | 73 | D |
| 5 | Adams County | 72.4 | D |
Across these five, the biggest risk driver is crime rates reported to law enforcement. Click any county for its full hazard, crash, crime and area profile.

How these scores are built
The composite blends three government datasets: natural hazard (FEMA National Risk Index, 45%), road safety (NHTSA fatal-crash records, 30%) and crime (FBI Crime Data Explorer, 25%). Each is expressed as a percentile against all U.S. counties, so a score of 80 means an area is riskier than 80% of the country. Full methodology and refresh dates are on our Data Sources page.

Scores are statistical percentiles for comparing areas, not predictions, and not a consumer report under the FCRA. See our Terms.
