Globally, the ageing population has been increasing faster than projected earlier. The number of people aged 60 and above is much higher than the number of children below five years. With an increasing life expectancy and decreasing birth rate, the demographic structure is changing with a rise in the number of older persons.
According to the World Health Organisation (WHO), about 12 per cent of people are aged 60 and above around the world. The number will be almost doubled by 2050. It is projected that 1 in 6 people will be 60 and above by 2030.
