The percentage of American children growing up to earn more than their parents has decreased from 90% in 1945 to 50% today. And even among the more successful of recent generations, such upward economic mobility varies across cities and demographic groups.
Harvard-based nonprofit group Opportunity Insights recently published data linking parent and child tax records, finding a significant gap in economic mobility attained by Black males compared with white males. However, data for females showed no racial mobility gap. And the racial mobility gap between Black and white males varied from city to city.
What could explain these findings? After all, Black males and females predominantly go to the same schools, live in the same areas, and can share the same homes. What about their lived experiences could explain this different outcome?
Institution for Social and Policy Studies faculty fellow Rourke O’Brien, an associate professor of sociology, and Manuel Schechtl, assistant professor of public policy at the University of North Carolina at Chapel Hill, constructed a study to test one possibility.
“This is one of these curious findings,” O’Brien said. “We had to think of a social factor that varied across places and differently impacted people based on both race and gender. We know that structural racism would drive outcomes between Black people and white people and that gender disparities would lead to differences between men and women. But what might disparately impact only Black males?”
In a paper published this month, O’Brien and Schechtl analyzed data in 200 major cities from the 1990s, when the subjects from the Opportunity Insights data were teenagers and young adults. They found that the racial mobility gap increased in relation to the per capita size of a city’s police force — for males but not females. In addition, they found that the increased exposure to police personnel during the teenage and young adult years of people studied led to a higher likelihood of incarceration for Black males compared with white males.
“For other groups — Black females, white males, and white females — there were better outcomes,” Schechtl said. “For them, more policing might have primarily meant less crime. But our findings are consistent with a large body of research showing that where there is more intensive policing, Black males are more likely to make contact with the criminal justice system, negatively impacting their levels of educational attainment and ability to secure a good job.”
