Using the EBRI IRA Database, this Issue Brief examines the trends in account balances, contributions, withdrawals, and asset allocation in IRAs from 2010-2015. Results from both the annual cross-sectional samples and a consistent sample of IRA owners who have been in the database in each year from 2010-2015 are presented. The cross-sectional overall average balance increased 36.1 percent from 2010 to 2015, while the increase for those IRA owners who continuously owned IRAs from 2010-2015 was 47.1 percent. Similarly, the cross-sectional share of assets allocated to equities increased from 45.7 percent in 2010 to 54.7 percent in 2015, while among consistent account owners, the share of assets allocated to equities increased from 44.5 percent in 2010 to 52.6 percent in 2015. Finally, among consistent Traditional IRA owners, 87.2 percent did not contribute to the IRA in any year, as opposed to 60.1 percent of consistent Roth IRA owners not contributing in any year.
