摘要

In the United States, the average life expectancy in 2004 was 75.2 years for men and 80.4 years for women; by 2015 it is expected to be 76.2 and 82.2 years, respectively, and to continue to grow. During the 1990s, the population older than 85 years was the fastest growing group at 38% growth. This older age group is the largest consumer of health care services.
