  范文:

  Aging of the Population

  Population officials and demographers have much to worry about China’s increasingly aging population. It is estimated that the proportion of people aged 60 or older in China will rise to 11.8 percent in 2020. By the middle of this century, people aged beyond 60 will take up 27.4 percent of the total population — that means one out of every four people will be senior!

  The aging population poses a serious challenge to families and the society. On the one hand, with families becoming smaller and living pace escalating, it is even graver for families to care for aged members adequately. On the other hand, aging causes a relative decline in working force. Consequently, the productivity of the whole society will be affected to some extent。

  The rapidity of the population’s aging has made it more urgent for the adoption of countermeasures. There is no doubt that the key is to build a solid economic foundation. Meanwhile, importance should be attached to overall social progress by changing the backward situation in social security, welfare and service. What’s more, family care and community-based services should also be encouraged。

  篇二:關于人口老齡化的問題

  The problem of old age is known as one of the most serious problem in today's world. The old people can be seen everywhere. As is shown in the graph, the number of people in the world over the age of sixty will have increased to 600 million by the end of this century. And by the time, there will also be twice as many people over the age of eighty. In the ten years between 1970 and 1980, there was a 23.7% increase in the number of people aged over sixty-five in the industrial world, and an even bigger increase of 38.2% in the developing world.

  With the development of economy, the rise in people's living standards and the improvement of medical conditions, people are living longer and longer. Furthermore, birth rates are falling as the pace of population growth slows down. As a result, the number of old people in the world is experiencing an increase. Though the increase will cause manifold social and economic consequences, we can take effective measures to deal with it. So I believe a bright tomorrow for old people will be achieved through efforts of every person.
