Based on the most recent comprehensive data, the gap between what state and local governments have promised in pension benefits to their workers and the funding to meet those obligations continues to widen.

A combination of investment return shortfalls, missed contributions, and unfunded benefit increases had left states with a $452 billion unfunded liability for pensions in fiscal 2008; by 2010 this funding gap had grown to $757 billion.
