while the workforce overall has shrunk nearly 10 million since 2009, the cohort of workers in the labor force ages 55 to 64 has actually increased over that same period, with many delaying retirement due to poor economic conditions.
over two-thirds of all labor force dropouts since that time have been under the age of 55.
