American Forests' Tree Equity Score combines tree canopy coverage, surface temperature, income, employment, race, age, and health data to identify where trees are needed most. Scores range from 0 to 100, and areas below 60 are priority for investment.

Equity Indicators
These factors show how tree canopy gaps overlap with social and environmental vulnerabilities.
1930s Redlining
29.2%
of neighborhoods were graded "hazardous" or "declining" on 1930s federal lending maps. Banks refused to invest in these areas, and many are still under-treed decades later.
Environmental Justice
4.2%
of neighborhoods are classified as overburdened by the White House's Climate & Economic Justice Screening Tool, meaning they face outsized pollution, poverty, or health risks. Trees help, but they're not the whole fix.
Heat Island Effect
-0.1°F
cooler than surrounding areas on average. The canopy is doing its job here.
