The average net worth of a family headed by someone born in the 1980s is 34% below what is expected, due to the Great Recession, according to a new study from the St. Louis Federal Reserve. The study found that loss to be higher than any other age group surveyed, and the discrepancy continued well after the end of the recession — primarily because the generation carries debts but is less likely to own an appreciating asset. Although millennial-headed families are unlikely to own real estate, they are still heavily in debt, with student loans, auto loans and credit card debt.
