Ozone Risk Map

The map shows the risk of ozone for people in each of Colorado’s census tracts — small geographic regions used for the US census. The risk is an index between 0 and 1, where 0 indicates lowest risk (lightest color) and 1 indicates the highest (darkest color). This index represents a combination of exposure and social vulnerability to ozone. Communities with a higher share of young people, older people, outdoor workers, and people with asthma or heart disease are more likely to be harmed by the impacts of ozone.

We have the power to curb the worst of climate change by taking action on eliminating pollution from our atmosphere and investing in the communities facing the greatest threats from climate change. To learn about solutions and actions you can take to act on these issues visit Impacts and Solutions.

Zoom in to see the ozone risk index in your census tract. You can use the search bar in the upper-left-hand corner of the map to type in your city or county. Hover over a census tract to see the components of the index in that area. You can also highlight multiple census tracts by clicking and dragging with your cursor.
