Housing segregation in Black history refers to the discriminatory practices and policies that prevented Black people from living in certain neighborhoods or communities. This practice, also known as "redlining," was pervasive in the United States, particularly during the early to mid-20th century.

One of the key ways housing segregation was implemented was through the practice of redlining, which involved the categorization of neighborhoods based on racial composition and perceived financial risk for lending purposes. Black neighborhoods were often designated as high-risk areas, making it difficult for Black residents to secure mortgages or loans to buy homes. This led to the concentration of poverty and limited economic opportunities for Black families.

Government policies, such as the Federal Housing Administration's underwriting guidelines, also played a significant role in perpetuating housing segregation by explicitly excluding Black neighborhoods from receiving federally-backed home loans. This further disadvantaged Black families and reinforced racial disparities in homeownership and wealth accumulation.

The effects of housing segregation continue to be felt today, as Black communities still face higher levels of poverty, limited access to quality housing, and disparities in homeownership rates compared to white communities. Efforts to address housing segregation and promote fair housing practices have been ongoing, but systemic inequalities persist and continue to impact Black individuals and communities.
