Just how common are defined benefit plans?

Not very. The percentage of workers in the private sector whose only retirement account is a defined benefit pension plan is now 10%, down from 60% in the early 1980s. About 30% of companies offer a combination of both types.

Meanwhile, the few employers that still offer traditional pensions - typically industries with a strong union presence, such as the airline and auto sectors - are working overtime to cut deals to either reduce or eliminate their plans.
