Finally, many studies have documented important racial differences in the economic returns to schooling. As young adults, black men have more trouble transitioning into stable full-time employment than white men do, and this racial difference is particularly pronounced among men with lower levels of education. In early adulthood, even college-educated black men earn less than white men, however.49 These differences in career entry alone help explain why black men are slower to marry than white men. But a difficult transition to stable employment is an even greater barrier to marriage for black men than it is for white men.
