Redlining in the United States
Redlining¹ refers to a racially discriminatory practice of disinvestment and exclusionary lending that systematically obstructed African Americans and other communities of color from accessing homeownership and economic mobility.² Originating in the 1930s, redlining was institutionalized by federal agencies such as the Home Owners' Loan Corporation (HOLC) and the Federal Home Loan Bank Board, which developed color-coded maps to evaluate the investment risk of residential neighborhoods. Predominantly white neighborhoods were marked in green as "best" for investment, while blue indicated "still desirable" areas, yellow denoted neighborhoods "definitely declining," and red signified areas deemed "hazardous"—the majority of which were heavily populated by Black residents. The red designations effectively discouraged banks and investors from offering mortgages and financial services to those areas, reinforcing racial segregation and contributing significantly to long-term Black poverty.
Impacts of Redlining
Racially Segregated Communities
Redlining reinforced racial residential segregation by directing investment away from communities of color, thereby creating racially homogenous neighborhoods with entrenched disparities.³ Today, nearly 64% of the neighborhoods classified as "red" by the HOLC remain predominantly non-white.⁴
Socioeconomic Disparities
Homeownership is a principal driver of intergenerational wealth in the United States. However, by restricting access to mortgages and investment opportunities, redlining severely limited wealth accumulation among African Americans. As of recent data, Black household wealth is estimated to be only about 5% of white household wealth.⁵ The lack of homeownership among communities of color also led to lower property values, reduced rental income, limited access to credit, and inflated borrowing costs—further discouraging private and public investment and contributing to the deterioration of urban neighborhoods.⁶
Health Outcomes
Redlining has had lasting health consequences.⁷ Studies have demonstrated that residents in historically redlined communities experience worse mental health outcomes, lower life expectancy, and higher rates of morbidity. On average, life expectancy is 3.6 years shorter in formerly redlined areas compared to their historically favored counterparts.
Crime and Social Disorganization
Redlined neighborhoods have also been associated with elevated crime rates.⁸ These areas exhibit characteristics of social disorganization—marked by high levels of poverty, ethnic heterogeneity, and frequent population turnover—all of which are linked to increased delinquency and reduced communal stability.
Redlining in Baltimore
Baltimore played a foundational role in the development of racially discriminatory housing policy. In 1910, Hawkins, a Yale-educated Black attorney, purchased a home on McCulloh Street—then considered a prestigious, majority-white neighborhood. This event prompted the enactment of Ordinance No. 610 in 1911, which instituted racial zoning laws prohibiting Black residents from moving into majority-white blocks. This ordinance became the first racial zoning law in the United States and served as a legal precursor to the redlining practices that would emerge nationally in the 1930s. Even before the formal adoption of redlining, the Baltimore City Housing Authority operated racially segregated and unequal public housing programs. Redlining entrenched a cycle of economic and racial disparity that continues to shape the socio-economic landscape of Baltimore to this day.
