Abstract:
With the advent of the twenty-first century, a new phenomenon in human history emerged, one that is expected to dominate the social, economic, health, and health care agenda of the United States and the world. This so-called "age wave" represents an unprecedented demographic trend that will make the oldest cohorts, especially those older than 75, 85, and 100 years old, the fastest growing segment of the population for at least the next 50 years.
