edlining is a discriminatory practice that involves denying or limiting financial services, such as home loans, to residents of certain neighborhoods, often based on the racial or ethnic makeup of those neighborhoods. This practice, which was widespread in the United States in the 20th century, effectively excluded many minority communities from access to mortgage financing and other financial services, and contributed to the segregation and devaluation of those neighborhoods.

Redlining was made illegal by the Fair Housing Act of 1968, which prohibits discrimination in the sale, rental, and financing of housing on the basis of race, color, religion, national origin, sex, familial status, or disability. However, the effects of redlining continue to be felt today, as minority neighborhoods often have higher rates of poverty, lower homeownership rates, and less access to credit and other financial services.
