In their latest study, Partnership member Raj Chetty and colleagues at the Equality of Opportunity Project analyzed data on 20 million children and their parents. The research shows substantial variations in upward mobility by race, including lower rates of upward mobility for black versus white boys even when a range of factors--parental income, neighborhood, parental marital status, education, and wealth--are held constant. "Differences in ability also do not explain the patterns of intergenerational mobility we document," the researchers write. "These findings," they conclude, "suggest that reducing the black-white income gap will require efforts whose impacts cross neighborhood and class lines and increase upward mobility specifically for black men."
