Using the Survey of Consumer Finances, I calculated various wealth series for young families with heads below the age of 35.
Here is median net worth for young families. I include both the net worth concept used by the Federal Reserve and a modified net worth concept that excludes vehicles. Insofar as vehicles are rapidly depreciating consumer durables, many argue that they should not be counted as assets for these purposes. Without these vehicles, the median young family had a net worth of $1,250 in 2016. This was down from the $7,846 peak in 1995.
The next graph also provides greater detail for the mean wealth of young families. It differs from the prior graph in that it shows major debt categories rather than major asset categories. Once again, the most conspicuous trend here is the run up of home debt during the housing bubble and the subsequent decline of that debt after the bubble burst.
Another major debt trend is student debt. This is better seen in the graph below, which shows how debt levels have changed in percent terms since 1989. Student debt increased over this period by 702%. The next closest debt category was vehicle debt, which only increased by 40.7%.
