The Aging of the Population

The Aging of the Population(人口老齡化)是指人口生育率降低和人均壽命延長導(dǎo)致的總?cè)丝谥幸蚰贻p人口數(shù)量減少、年長人口數(shù)量增加而導(dǎo)致的老年人口比例相應(yīng)增長的動態(tài)。

當(dāng)一個國家或地區(qū)60歲以上老年人口占人口總數(shù)的10%,或65歲以上老年人口占人口總數(shù)的7%,就意味著人口老齡化了。

我們來看2個例句:

How to solve the aging of the population and the problems brought about by in such a developing country is an extremely challenging reality.

如何解決人口老齡化及其所帶來的問題在我們這樣一個“未富先老”的發(fā)展中國家是一個極具挑戰(zhàn)性的現(xiàn)實問題。

As the aging process of China's population structure is accelerating, the aging of the population issue has become the focus of attention.

隨著我國人口結(jié)構(gòu)老年化進(jìn)程的加速,人口老齡化問題已經(jīng)成為全社會關(guān)注的焦點。
