The growing gap by education is even more apparent when looking at annual household income. For households headed by Millennials ages 25 to 37 in 2018, the median adjusted household income was about $105,300 for those with a bachelor’s degree or higher, roughly $56,000 greater than that of households headed by high school graduates.
This modest difference in wealth can be partly attributed to differences in debt by generation. Compared with earlier generations, more Millennials have outstanding student debt, and the amount of it they owe tends to be greater. The share of young adult households with any student debt doubled from 1998 to 2016. In addition, the median amount of debt was nearly 50% greater for Millennials with outstanding student debt.
