The EBRI/ICI report, 401(k) Plan Asset Allocation, Account Balances, and Loan Activity in 2009, is based on the largest database of its kind, with records on 20.7 million participants at year-end 2009, including 4.3 million consistent participants—those who have had 401(k) accounts with the same 401(k) plan each year from year-end 2003 through year-end 2009.
The full report is being published simultaneously by EBRI and ICI and is on their websites (EBRI's is here, ICI's is here). The joint press release is here.
