According to a new report from the Federal Reserve, the average family lost around 40% of their net worth between 2007-2010. The report shows that the decrease hit many different demographics, with lower and and middle income households being hurt the most because of the housing bubble. The current median net worth remains below pre-recession levels, even as people struggle to recover.
