4.5 Redlining and Housing Discrimination

Redlining was the practice of denying mortgages and loans to African Americans and other people of color by labeling their neighborhoods as "hazardous" financial risks. Combined with the Federal Housing Administration's 1938 Underwriting Manual and racially restrictive practices, this housing discrimination blocked Black families from homeownership, limited the wealth they could pass down, and deepened racial gaps.

Government policy and private lending reinforcing racial inequality is a pattern you can use across Unit 4 and beyond. It also lets you link housing discrimination to the wider Civil Rights movement.

How Housing Discrimination Shaped Black Wealth and Communities

• Housing discrimination limited Black homeownership, which limited the wealth families could pass to their children and widened the racial wealth gap.
• The Federal Housing Administration's Underwriting Manual (1938) codified housing segregation, and the NAACP helped push for the Fair Housing Act in 1968.
• Redlining meant mortgage lenders withheld loans from African Americans and other people of color in mapped areas labeled "hazardous."
• African Americans who moved into well-resourced, mostly white neighborhoods sometimes faced mob violence.
• Housing discrimination worsened gaps in transportation, clean water and air, recreation, healthy food, and healthcare, which fed health disparities along racial lines.
• Black communities responded to unequal transit by running jitneys and starting their own bus companies.

Housing Discrimination and Generational Wealth

Throughout the twentieth century, African Americans faced restrictions on buying homes. That mattered because homeownership is one of the main ways American families build wealth and pass it to the next generation. When Black families were blocked from owning property, they were also blocked from building equity and handing down that wealth, which kept disparities locked in place over time.

These restrictions did not come from one source. They came from federal policy, private lenders, and neighborhood-level practices working together.

How Housing Segregation Was Codified

Housing segregation was written into federal policy through the Federal Housing Administration's Underwriting Manual (1938). The manual treated African American neighborhoods as poor risks for lending, and the restrictions that followed made it effectively impossible for African Americans to live in many communities across the United States.

The NAACP fought housing discrimination over the long term, and its work contributed to the passage of the Fair Housing Act in 1968, which targeted racial discrimination in housing.

What Redlining Was

Redlining was the discriminatory practice of withholding mortgages from African Americans and other people of color within a defined geographic area. Lenders justified it by claiming those communities were a "hazardous" financial risk, even though the label was based on race rather than actual lending data.

This practice ran throughout the twentieth century and peaked in the mid-1900s. Government-backed maps marked neighborhoods by perceived risk, and areas with Black residents were often the ones cut off from loans.

Long-Term Effects of Redlining

• Families shut out of homeownership could not build home equity or pass it down.
• Communities labeled "hazardous" struggled to attract investment.
• Without access to mortgages, many residents were pushed into renting, which made it harder to build stable, long-term wealth.

Violence Against Integration

Some African Americans did move into well-resourced neighborhoods, and when they did, they sometimes became targets of mob violence. This violence was one of several tactics used to keep neighborhoods segregated, and it shows that housing discrimination was enforced socially as well as through official policy.

Unequal Resources and Health Disparities

Housing discrimination intensified gaps that already existed between African Americans and white Americans. Many Black communities had limited access to public transportation, clean water and air, recreational spaces, healthy food, and healthcare services. Those gaps were not just inconveniences. They built up into real health disparities that fell along racial lines.

When a community is cut off from clinics, grocery stores with fresh food, and clean environments all at once, the effects compound. That is why housing policy connects directly to health outcomes in this topic.

Transportation Inequality and Black Responses

Predominantly Black areas often lacked enough infrastructure for public transportation, and segregated transit stayed unequal. Rather than accept being cut off from jobs and services, African Americans built their own solutions. They operated jitneys, small buses that worked like taxi services, and they started their own bus companies to serve their communities.

Required Sources

Home Owners' Loan Corporation "Residential Security" Map of Philadelphia and Camden, 1937

This map is a primary record of how redlining worked on the ground. A federal agency color-coded neighborhoods to guide mortgage lending, and areas marked as "hazardous" were often the ones where Black residents lived. When you analyze it, focus on how an official-looking document turned racial bias into routine lending policy, and how that shaped which neighborhoods got investment and which did not.

Excerpt from A Raisin in the Sun by Lorraine Hansberry, 1959

Lorraine Hansberry's play follows a working-class Black family in Chicago as they try to move into a new home and a better future. The excerpt lets you see housing discrimination through the eyes of a single family rather than a map or a policy. The title of the play was inspired by Langston Hughes's poem "Harlem." When you use this source, connect the family's choices and obstacles to the larger patterns of restriction described in this topic.

Analyzing Sources and Building Housing Arguments

Using Sources Effectively: Both required sources reward close reading. For the Home Owners' Loan Corporation map, identify who made it, what the color coding did, and what effect it had on Black neighborhoods. For the A Raisin in the Sun excerpt, track how the characters experience the pressure of housing discrimination, and tie that lived experience back to policies like redlining and restrictive practices.

Argument and Evidence: When a prompt asks about causes or long-term effects, use the chain in this topic: discrimination blocked homeownership, blocked homeownership limited inherited wealth, and that gap widened over time. You can strengthen an argument by naming the Underwriting Manual (1938), redlining, the Fair Housing Act (1968), and the NAACP's role.

Continuity and Change: This topic works well for continuity and change questions. Redlining peaked in the mid-1900s, and the Fair Housing Act came in 1968, so you can show both the long persistence of discrimination and the point where federal law shifted.

Common Trap: Do not treat the Fair Housing Act of 1968 as if it erased the damage. The law targeted future discrimination, but decades of blocked wealth-building and disinvestment had already shaped where families lived and what they could pass down.

Common Misconceptions

• Misconception: Redlining was just individual prejudice.
  Actually: Redlining was not just individual prejudice. It was a systematic practice tied to maps and lending rules, with federal policy giving it structure through the FHA's Underwriting Manual.
• Misconception: "Hazardous" ratings were based on real financial data about borrowers.
  Actually: "Hazardous" ratings were not based on real financial data about borrowers. The label was applied to neighborhoods because of who lived there, not because of objective risk.
• Misconception: The Fair Housing Act of 1968 undid past harm.
  Actually: The Fair Housing Act of 1968 did not undo past harm. It aimed at stopping ongoing discrimination, but the wealth gaps created by earlier policy continued.
• Misconception: Housing discrimination was only a Southern issue.
  Actually: Housing discrimination was not only a Southern issue. The maps and practices in this topic affected cities across the United States, including Northern ones like Philadelphia and Camden.
• Misconception: African Americans were passive in the face of these barriers.
  Actually: African Americans were not passive in the face of these barriers. Communities responded actively, including by running jitneys and starting their own bus companies when transit was unequal.
