The budding ageing population challengesListen /
The United Nations says there are approximately 810 million persons aged 60 years or more in the world in 2012 and by 2050, this number is projected to grow to more than two billion.
By then, older persons will outnumber the population of children from birth to 14 years of age for the first time in human history.
Asia has more than half, 55 per cent, of the world's older persons, followed by Europe, which accounts for 21 per cent of the total.
