Ageing Demographics

Ageing Demographics

Ageing demographics also known as Population ageing is the increase in age of a population confined to a particular region which may be due to rising life expectancy or declining potential natality. The population of aged is by far the highest in human history. Since 1950, the number of people above 60 years of age has increased three fold, reaching 600 million in 2000 and exceeding 700 million in 2006. Study says that the geriatric population will reach 2.1 billion by 2050.

The population aged 60 years and above was estimated to be 605 million in 2000 and is predicted to grow to nearly 2 billion by 2050. Persons aged 60 or older currently accounts for 10 per cent of the world’s population. Developed countries have a higher percentage compared to the developing countries accounting to 20 per cent and 8 per cent respectively. The least developed countries only account to 5 per cent. Greece and Italy are the countries which have high number of aged people. By 2050, we can see that many European countries will also have the same demographics.  The final statistics of old age will make up to 22 per cent of world population, 33 per cent in developed regions and 12 per cent in the under developed regions.

When regions are taken into consideration, the majority of world’s aged people reside in Asia accounting to 53 per cent, next comes Europe with 24 per cent. Research states that by 2050, Asia’s share of the older population will increase to 63 per cent while Europe will show a decrease from 24 percent to 11 percent.
