The relative rarity of banks in nonwhite neighborhoods is exacerbating the racial wealth gap by leaving African Americans more reliant on expensive financial services such as payday lending institutions, according to Reuters, citing research by McKinsey & Co. The study found that majority-white counties have an average of 41 financial institutions per 100,000 people, compared to 27 in nonwhite majority neighborhoods. It also found banks in majority-black neighborhoods tend to require a higher minimum account balance, with an average minimum of $871 in black neighborhoods compared to $626 in white neighborhoods.
