What to know about Today's urban inequality goes far beyond legacy of 'redlining,' study shows

A study published in the Proceedings of the National Academy of Sciences (PNAS) examines urban inequality in Portland, Oregon, finding that while historical redlining created lasting disparities, current patterns of privilege and disadvantage are also driven by gentrification and displacement. The researchers argue that policymakers must consider a broader range of socioeconomic and environmental factors beyond historical redlining to create equitable cities.
