The recent financial crisis left the median American family in 2010 with no more wealth than they had in the early 1990s, erasing almost two decades of accumulated prosperity, the Federal Reserve said Monday.

The median family, richer than half of the nation’s families and poorer than the other half, had a net worth of $77,300 in 2010, down from $126,400 in 2007, the Fed said. The crash of housing prices explained three-quarters of the loss.
