The number of people over 60 years old is projected to double in the next 20 years. Most of these older persons will be living in developing countries. Reducing and postponing age-related disability is an essential public health measure and physical activity can play an important role in creating and sustaining well-being at all ages. WHO
AS WE ENTER THE TWENTY FIRST CENTURY, population aging has emerged as a major demographic trend worldwide. Declining fertility, and improved health and longevity, have swelled the older populations dramatically—and at an unprecedented rate.
For the first time in history, people aged 65 and over will soon outnumber children under the age of 5.
By 2030, 55 countries are expected to see their 65 and older populations at least 20 percent of their total.
