Redlining is against the law. It is a discriminatory practice, involving lenders which refuse to lend money or extend credit to borrowers in certain "struggling" areas of town. It is against the law to discriminate against borrowers based on race or income level, among other factors.
Redlining became known as such because lenders would draw a red line around a neighborhood on a map, often targeting areas with a high concentration of minorities, and then refusing to lend in those areas because they considered the risk too high. Even though it is now against the law, some lenders today are still accused of redlining.
