What are the requirements of the children and the aged people?
Answers
Answer:
Between 2015 and 2050, the proportion of the world's population over 60 years will nearly double from 12% to 22%.
By 2020, the number of people aged 60 years and older will outnumber children younger than 5 years.
In 2050, 80% of older people will be living in low- and middle-income countries.
The pace of population ageing is much faster than in the past.
All countries face major challenges to ensure that their health and social systems are ready to make the most of this demographic shift.
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. By 2050, 80% of all older people will live in low- and middle-income countries.
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.
