Reveal News has done a good investigation on modern redlining from data gathered from the Home Mortgage Disclosure Act. This is what they do report for the Detroit, Dearborn, Livonia area.

Reveal found evidence suggesting discrimination in the DETROIT-DEARBORN-LIVONIA, MI metro area. In 2016, black applicants were 1.9 times as likely to be denied a conventional home mortgage as white applicants. There weren’t enough conventional loan applications in this metro area from Native American applicants to draw a conclusion. For Asian and Latino applicants, there were enough applications, but other statistical factors made it difficult to draw a conclusion.
