Historically ‘redlined’ urban areas have higher levels of air pollution

In the wake of the Great Depression, the federally sponsored Home Owners’ Loan Corporation drew maps of neighborhoods in U.S. cities that characterized their desirability for mortgage lending. Many neighborhoods with Black and immigrant communities received the worst grade, restricting access to federally backed loans and favorable mortgage terms. Now, researchers have found that these ‘redlined’ areas have higher levels of air pollution 80 years later.
