The government didn't just allow discrimination. It mapped it, funded it, and enforced it.
Between 1935 and 1968, the federal government systematically excluded Black Americans from the greatest wealth-building program in American history. While white families used federally subsidized mortgages to buy homes that tripled in value, Black families were locked out by federal policy, not individual prejudice. The racial wealth gap today is the predictable result.
Federal agents graded every neighborhood in 239 American cities. The grading criteria were explicit about race.
New, homogeneous, in-demand neighborhoods with no 'infiltration' of foreign-born residents or 'Negroes.' Banks would freely lend here.
Typical resident: White, native-born, middle to upper classOlder but stable neighborhoods. Would receive loans, though with stricter terms than Grade A.
Typical resident: White, mixed classNeighborhoods noted for 'infiltration' of 'foreign-born families' or other groups deemed undesirable. Loans possible but expensive.
Typical resident: Mixed, including recent immigrantsAny neighborhood with Black residents — regardless of income, home condition, or stability — was graded D. Banks would not lend. The word 'redlining' comes from the literal red lines drawn around these areas.
Typical resident: Black residents, regardless of class or incomeThe HOLC maps are now publicly available through the University of Richmond's Mapping Inequality project. You can look up your city and see exactly how your neighborhood was graded in 1935 — and compare it to income and health outcomes today.

Federal agents surveyed 239 cities and created color-coded maps rating neighborhoods for lending risk. Any area with Black residents was graded D (Hazardous) by default — not because of housing quality, but because of race. Banks used these maps as the standard reference for decades.
The FHA's official underwriting manual explicitly warned against lending in 'inharmonious racial groups' and recommended deed restrictions barring Black buyers. The manual stated that 'incompatible racial elements' would lower property values. This was federal policy, not individual bank bias.
The Servicemen's Readjustment Act of 1944 (GI Bill) offered low-interest mortgages, college tuition, and business loans to 16 million veterans. The VA administered the program through private banks — which refused to extend loans to Black veterans or in Black neighborhoods. The federal government did not require nondiscrimination.
Deed covenants contractually prohibited the sale of homes to Black buyers. Enforceable in court until Shelley v. Kraemer (1948), which ruled them unenforceable — but the FHA continued insuring subdivisions with covenants for years afterward. Many covenants remain in original deeds today.
Black families desperate to buy in cities were sold homes on 'contract' — they paid monthly installments but held no equity and could be evicted for missing a single payment, at which point all prior payments were forfeit. Sellers often bought from white owners at market price and resold to Black buyers at 2–3x markup with no path to ownership.
Redlining was not a Southern phenomenon. It shaped every major American city.
The South Side and West Side were comprehensively redlined. Between 1930 and 1960, Chicago's Black population grew from 233,000 to 813,000 — almost entirely contained within the redlined zone. By 1960, 25% of the city's population occupied 9% of the land. Contract selling extracted hundreds of millions of dollars. Public housing projects were deliberately sited in redlined areas to reinforce segregation.
Baltimore was one of the first cities to enact racial residential zoning (1910). The HOLC maps reinforced decades of existing segregation. Black residents were confined to a narrow band of the city, paying premium prices for substandard housing. The Interstate Highway System (I-95, I-83) was routed through Black neighborhoods in the 1950s–60s, destroying the communities that had survived redlining.
Atlanta's HOLC maps graded every Black neighborhood D regardless of income. Sweet Auburn — described in the HOLC's own documents as the "best negro section in Atlanta" — was graded Hazardous anyway, with instructions to sell properties "as quickly as possible." Black families who had built wealth were excluded from the postwar mortgage market while white suburbanization was federally subsidized.
Detroit's auto industry employed hundreds of thousands of Black workers who migrated from the South. The HOLC mapped 200 Black neighborhoods as D, while the FHA insured all-white suburbs like Dearborn and Grosse Pointe. White workers built equity; Black workers paid rent. The 1967 uprising occurred in neighborhoods that had been redlined for 30 years.
A 2020 study by the NCRC and three universities analyzed health and economic outcomes in 142 cities and found that formerly redlined neighborhoods have significantly higher rates of asthma, heart disease, diabetes, and premature death — outcomes that directly track 80-year-old lending maps.
The Federal Reserve's 2022 Survey of Consumer Finances found the median white family holds $284,310 in wealth; the median Black family holds $44,890 — a 6:1 ratio. Homeownership accounts for the majority of American household wealth, and the homeownership gap traces directly to the federally enforced exclusion of the GI Bill era.
In 2021, Evanston, Illinois became the first American city to offer reparations for redlining — $400,000 in housing assistance funded by a tax on cannabis sales. No federal reparations program exists.
"The Fair Housing Act of 1968 outlawed redlining. But it did not undo it. A family locked out of the postwar wealth boom had no mechanism to recover the equity that was never built."
