According to estimates by the United Nations Population Division (UNPD) of the Department of Economic and Social Affairs, China now has one of the lowest child dependency ratios (the ratio of the population aged 0–14 to the population aged 15–64), as its child dependency ratio declined 60 per cent during the 1980–2015 period. Meanwhile, China’s old-age dependency ratio (the ratio of the population aged 65 years or over to the population aged 15–64) keeps increasing, and its population ageing is accelerating. Currently, the total dependency ratio in China is about 38 per cent, which is considered low globally. With further demographic transition and the decline of the ‘demographic dividend’, it is estimated that China’s total dependency ratio will exceed 75 per cent by 2055, much higher than the estimated global average.
