“The Center for State and Local Government Excellence and the Center for Retirement Research at Boston College have partnered to develop the Public Plans Database (PPD). The PPD contains comprehensive financial, governance, and plan design information for 126 state and local defined benefit plans, along with additional data on state defined contribution plans.

• At the state level, the PPD covers 107 plans, which represent more than 90 percent of all state government pension assets and members.
• At the local level, the PPD covers 19 plans, which represent more than 20 percent of all local government pension assets and members.
• On a combined basis, the PPD represents more than 85 percent of total state and local government pension assets and members.
• Data are collected from plans, annual reports, actuarial valuations, member handbooks, and contact with plan administrators.”
