The data provided by the Center includes 2006 information on participation, contribution rates, investment allocation, total assets, and distribution options, among other things. The Center said the data will be updated annually and filled in for previous years.
In addition, the Center has released defined benefit plan data for 126 plans largely administered by states. The effort was coordinated with the Public Fund Survey.
The Center said it will release information on municipal pension plans later this year.
