Global aging: implications for women and women's health.

The world's older population has been growing for centuries; however, the pace of this growth is accelerating rapidly. According to the U.S. Census Bureau, by 2030, more than 60 countries will have 2 million or more older people. Population aging represents a "success story," with increasing numbers of people worldwide enjoying additional years of life. However, the sustained increase in numbers of older people (usually defined as persons over the age of 65) poses many challenges to policy makers and health care providers around the world. As the world population ages, we are just beginning to understand the social, economic, and political implications of the "age wave." The majority of older people are women, thus the implications of population changes for women and women's health are astounding. Nurses can take a national and world leadership role to adequately address the health care needs of increasing numbers of older women.
