Redlining is the illegal practice of denying or increasing the cost of goods and services based on a buyer's race or socioeconomic status.
Background
The term "redlining" was coined by Chicago-based community activists in the late 1960s to describe the practice of marking a map with a red line to denote the neighborhoods banks shouldn't invest in. Today, the term generically refers to any bank, insurance company, health care entity or business that refuses service to those in economically disenfranchised neighborhoods.
