This was more than double the next-largest increase in net worth since 1989, when the Fed began the survey.
Median net worth — which measures household assets like houses and vehicles, minus debts like mortgages and student loans — surged to $192,000 when accounting for inflation.
While this group, comprised of younger millennials and Gen Zers, has a much smaller net worth than any other age group, median net worth grew from $16,100 to $39,000 during the three-year period.
So-called DINKs, or couples with "double income, no kids," also saw huge net worth increases, according to the Fed's survey.
Americans in the 55 to 64 age group saw median net worth gains of 48%, while those between the ages of 65 and 74 had a 33% rise in median net worth.
