1 . People worldwide are living longer. Today, for the first time in history, most people can expect to live into their sixties and beyond. By 2050, the world’s population aged 60 years and older is expected to total 2 billion, up from 900 million in 2015. Today, 125 million people are aged 80 years or older. By 2050, there will be almost this many (120 million) living in China alone, and 434 million people in this age group worldwide.

The pace of population ageing around the world is also increasing dramatically. France had almost 150 years to adapt to a change from 10% to 20% in the proportion of the population that was older than 60 years. However, places such as Brazil, China and India will have slightly more than 20 years to make the same adaptation.

A longer life brings with it opportunities, not only for older people and their families, but also for societies as a whole. Additional years provide the chance to undertake new activities such as further education, a new career or a long ignored passion. Older people also contribute in many ways to their families and communities. Yet the extent of these opportunities and contributions depends heavily on one factor: health.

There is, however, little evidence to suggest that older people today are experiencing their later years in better health than their parents. While rates of severe disability have declined in high­income countries over the past 30 years, there has been no significant change in mild or moderate disability over the same period.

If people can experience these extra years of life in good health and if they live in a supportive environment, their ability to do the things they value will be of little difference from that of a younger person. If these added years are affected by declines physically and mentally, the results for older people and for society are more negative.
