Outstanding student loan balances in the United States total roughly $1 trillion, with student loan debt following one of every five adults. People across the income, age, and educational attainment spectrums have student loan debt, but it is particularly concentrated in some groups. African Americans and Hispanics are about twice as likely to have student loan debt as whites. Fifty-seven percent of people with student loans are concerned that they may be unable to repay that debt. This concern cuts across demographic and economic groups but is more prevalent among people with children, with lower household incomes, and women.
