Most workers had only one type of retirement plan in March 2008, but some had two.
Forty-three percent of private-industry workers had a defined-contribution plan and 20 percent had a defined-benefit plan.

Among occupational groups, the rate of participation in retirement plans was highest among management, business, and financial employees–77 percent. The lowest rate of participation was that of service workers–25 percent.
