WASHINGTON, Aug. 9 (UPI) -- State pension systems across the United States total $2.5 trillion in cash and holdings in 2011, a 14.6 percent increase over 2010, the U.S. Census Bureau said.
Earnings on investments last year were $410.6 billion, up from $291.1 billion in 2010, the Commerce Department agency said Thursday in a release.
The bureau said the statistics were from the "2011 Annual Survey of Public Pensions: State-Administered Defined Benefit Data," which examines financial activity and membership information for the nation's 222 state-administered, public-employee retirement systems, including revenues, expenditures, investment holdings, membership and beneficiaries.
Total revenue increased 32.8 percent, from $389.0 billion in 2010 to $516.5 billion in 2011.
Total payments rose 8.5 percent in 2011, from $174.2 billion in 2010 to $189.0 billion the previous year.
