IRA asset allocations vary by age, balance and type, but the difference between genders is minimal, according to a new report by the Employee Benefit Research Institute.

Older individuals with higher account balances or who own a traditional IRA that originated as a rollover had, on average, lower allocations to equities. The report notes that as account balances increased, the percentages of assets in equities and balanced funds decreased, while bond and other asset shares increased.

Equity allocations for the youngest IRA owners (under age 35) with small account balances were the lowest across the age groups. When balances reached $10,000 or more, younger IRA owners had significant increases in equity allocations.
