The Annual Survey of State & Local Public-Employee Retirement Systems provides revenues, expenditures, financial assets, and membership information for public employee retirement systems. Data are shown for individual retirement systems as well as at the national, state, and local level. There were 3,418 public employee retirement systems in the sampling frame, of which 1,798 systems were selected for the sample. The increase in the number of systems from 2008 to 2010is due to an increase in coverage of the retirement systems in Florida, Illinois, Minnesota, Pennsylvania, and Texas. A sample of these units was added in 2010. The coverage was improved through research and greatly impacted the local retirement systems universe. Any year-to-year comparisons should be exercised with caution.
The 2010 survey covered fiscal years that ended between July 1, 2009 and June 30, 2010 and does not reflect data for the entire calendar year of 2010.
