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
2.1%
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
0.0%
No neighborhoods here meet the federal threshold for environmental and economic burden. That's a good thing.
Heat Island Effect
+7.8°F
hotter than surrounding areas on average. Pavement absorbs heat, trees block it. That's the whole pitch.
People in the Data
58,104
people live across the 48 Census block groups we analyzed. That's who these numbers represent.
