     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 l person in every 10 aged 60 or above. 1._____ 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?

     2._____ And another is that birth rates have dropped as people, especially women, are educated. Measures

to slow population growth like China's one-child policy, have also contributed to lowered birth rates. The

increase in the aged population is not just an interesting trend, however; it also has severe implications for the

future of global economies.

to ensure an active and productive old age. 5._____ By finding cures for diseases like Alzheimer's and cancer,

medical bills and the need for care would be drastically reduced.

valuable members of society only as pensioners or patients. It's high time we stopped seeing ageing as a disease

and started playing our parts in securing the future of our ageing societies.

A. Due to ageing problem, cities are facing more challenges.
