Environmental Justice communities are census tracts within Oakland that (a) face the greatest social-economic and pollution burdens and more risks of harm (exposure); (b) are more susceptible to the impacts of those harms; and (c) have less capacity to mitigate the impacts of the harms they experience. The most burdened communities represent the top 10th percentile of census tracts experiencing these issues. More information on how the Environmental Justice communities were developed is available in the Environmental Justice Element.
