Today, 870,000 people turn the grand age of 65 each month, making them 7% of the world’s population. But by 2019, this figure is set to stand at 1.9 million, according to the US census department. The number of under-5’s currently account for around 9% of the population.
Improvements of healthcare, diet and lifestyle are believed to have caused this unprecedented growth in the number of those aged 65 and over. Experts even believe that by the middle of the century the world will have 6 million centenarians compared to just 340,000 today.
“For the current middle-aged people, it will be comforting to think they can live past 80. At the same time, we might see 70 year old “kids” taking care of their centenarian parents,” Wan He, the co-writer of the report has said.
Europe is currently the greyest continent, with 23 of the world’s 25 oldest countries. The UK comes in at number 19 in the list of the world’s oldest countries, with the average life expectancy of 78.8 years. Topping the list is Japan, with 82 years.
