redlining is the practice of denying services, either directly or through selectively raising prices, to residents of certain areas based on the racial or ethnic composition of those areas. While the best known examples of redlining have involved denial of financial services such as banking or insurance,[2] other services such as health care[3] or even supermarkets[4] have been denied to residents (or in the case of retail businesses like supermarkets, simply located impractically far away from said residents) to result in a redlining effect.[5] The term "redlining" was coined in the late 1960s by John McKnight, a sociologist and community activist.[6] It refers to the practice of marking a red line on a map to delineate an area where banks would not make loans; later the term was applied to discrimination against a particular group of people (usually on the basis of race or sex) irrespective of geography.
