I am looking for information on percentages on distributions from retirement plans or programs on a national level. Specifically, employer related retirement plans or programs distributions vs. non-employer related plans or programs (IRAs and Rollover IRAs). If anyone has information on this subject, I would appreciate any assistance they can provide. Thank you.

The Investment Company Institute has a lot of information in this area. I'm not sure that they will have an answer to your specific question, though. Their web site is www.ici.org.
