The aging workforce, controversially referred to as The Silver Tsunami, refers to the rise in the median age of the United States workforce to levels unseen since the passage of the Social Security Act of 1935. It is projected that by the year 2020, about 25% of the U.S. workforce will be composed of older workers (ages 55 and over). While many factors contribute to the aging workforce, the Post-World War II baby boom created an unusually large birth cohort for the U.S. population, resulting in a large aging population today. This phenomenon has many short-term and long-term implications, affecting many areas, including the U.S. economy, society and public health.
