"AARP conducted a telephone survey of 2,001 individuals between the ages of 50 and 70 years old who are employed on a full-time or part-time basis. Of the individuals interviewed, more than eight in ten (85%) have never retired from a job; and fifteen percent report that they have retired from a job but either remained in the workforce after rehiring or have since returned to the workforce. The phone interviews, which were conducted by RoperASW using random digit dialing, took place from April 9 through June 5, 2003." (p.4)
