Power to the pensioners: growing elderly population means more political leverage by 2050

In 2019, about one in every 11 people on Earth was 65 or older. By 2050, that number will nearly double, rising to one in six, according to the United Nations. 

The World Health Organization says the number of people 60 or older will more than double from 2015 to 2050, from 900 million to 2 billion.
