The release of the Federal Reserve’s 2010 Survey of Consumer Finances (SCF) is a great opportunity to assess how conflicting forces – the maturation of the system and the Pension Protection Act of 2006 on the one hand and the devastating effects of the 2008 financial collapse and Great Recession on the other hand – have affected workers’ 401(k) accounts. The SCF is a triennial survey of a nationally representative sample of U.S. households, which collects detailed information on their assets, liabilities, and demographic characteristics. The 2001, 2004, and 2007 surveys showed some improvement in terms of 401(k) participation, contribution levels, investment choices, and cashing out. But median holdings of those approaching retirement remained low even at the peak of the market in 2007. This brief explores the extent to which the positive trends in 401(k) behavior have persisted in the weak economy and how balances have fared in the wake of the financial collapse.
