Are Societies Ageing Too Fast?
An ageing society is one in which the population of people over the age of 60 is increasing.The global population at present is about 6 billion with 1 person in every 10 aged 60 or above.__71__.This will mean that for the first time in human history the population of older persons will be larger than the population of children! What are the causes of this population change?
__72__.And another is that birthrates have dropped as people, especially women, are educated.Measures to slow population growth like China’s one-child policy, have also contributed to lowered birthrates.The increase in the aged population is not just an interesting trend, however; it also has severe implications for the future of global economies.
People traditionally retire at 65 and live on government pensions.__73__.Another concern is that as medical expenses increase with age, the demands of the growing aged population will eventually cause medical systems to face bankruptcy(破产).
