The wealth gap between Blacks and Whites has grown by fourfold over the course of Generation X’s lifetime, exploding to $95,000, a study released today found. And the debt burden among African American families has nearly doubled.

Shapiro’s research team looked at data from a decades-long, national survey of family economics and discovered that, between 1984 and 2007, the wealth gap saw unprecedented growth, as assets among high-income White households shot up while debt among all Black households did the same.
