Women with degrees work longer
A recent study of working women by Penn State labor economist Elizabeth Hill revealed an unexpected correlation between college education and working past retirement age. While Ms. Hill had suspected that for economic reasons high school-educated women would work later in life than college-educated women, it turns out that almost twice as many college-educated work past the age of seventy. The study also revealed that the driving force behind continued workforce participation beyond the age of retirement is the greater job flexibility available to women with higher-educations.
