The world’s population is rapidly ageing

The number of people aged 60 years or older will rise from 900 million to 2 billion between 2015 and 2050 (moving from 12% to 22% of the total global population).

Population ageing is happening more quickly than in the past. For example, while 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, places like Brazil, China and India will have slightly more than 20 years to make the same adaptation.
