While 98% of government-backed mortgages in the mid-20th century were restricted to white neighborhoods, a deliberate and systemic practice known as redlining codified racial segregation into the very geography of American wealth, creating a stark economic divide that still poisons our cities today.
Key Takeaways
- The Home Owners' Loan Corporation (HOLC) produced residential security maps for 239 cities across the United States between 1935 and 1940, grading neighborhoods from A (best) to D (hazardous)
- Of all the neighborhoods mapped by HOLC, approximately 75% of those graded 'D' (redlined) had majority Black residents
- HOLC maps explicitly considered racial composition in grading, with Federal Housing Administration (FHA) underwriting manuals stating "inharmonious racial groups" as a risk factor
- 64% of Black Americans lived in redlined neighborhoods in 1940
- In 1930s-40s, 85% of redlined areas nationwide had Black populations over 10%
- Latino neighborhoods in Southwest cities were redlined at 70% rate, e.g., Los Angeles Boyle Heights
- Homeownership rate in redlined areas today is 30 percentage points lower for Blacks
- House values in former redlined areas are 25% lower on average in 2020
- Redlined neighborhoods have 2.7x higher poverty rates than non-redlined peers
- Life expectancy 3.6 years shorter in redlined neighborhoods
- Asthma hospitalization rates 2.4x higher in former redlined areas
- Lead exposure risk 35% higher due to older housing stock in redlined zones
- 40% of redlined areas remain high-poverty today
- $156 billion wealth gap attributed to redlining legacies per 2020 estimates
- Only 17% of redlined tracts gentrified by 2010 vs 40% of others
Historical government redlining systematically denied Black communities wealth, creating lasting inequalities.
