在世界人口走向老龄化和发达国家人口老龄化发展的同时，中国人口老龄化也在加剧。人口老龄化的产生，正是社会进步、经济发展的结果。中国人口转变一般被认为始于新中国成立，起先是死亡率明显而迅速地下降。而全国性的生育率转变则始于20世纪70年代初期国家计划生育政策的介入，并迅速由高生育率水平转向低生育率水平。这样，人口的老龄化就导致了劳动力人口负担不断增大的问题，影响了我国社会经济的发展，并对相应基础设施、法律制度等物质及精神各方面的建设提出了新的要求。
针对这一情况全国老龄委发布了《中国老龄事业发展“十一五”规划》，提出了“十一五”期间，中国在养老保障、医疗保障、社会救助等，以及老龄事业基础设施建设、老年产业、老年精神文化生活等方面所要实现的目标和任务。我们既要正确认识中国人口老龄化的形成原因、基本特征、发展趋势以及可能产生的社会经济后果，更要弄清人口老龄化对社会经济运行及可持续发展的影响。惟此，才能提高决策的科学性和可行性，解决好人口老龄化问题，为实施可持续发展战略创造有利的人口环境。通过对人口老龄化的科学内涵的界定，明确我国人口老龄化的成因。通过对人口老龄化的演进过程的研究，重点阐述我国人口老龄化的特征及其对经济、社会和家庭等各方面的影响，从而解决自身不足，提出解决人口老龄化问题的相应对策措施。
Of the world's population aging and the aging of the population in developed countries the same time, China's aging population has intensified.

Aging of Population in China
Many countries will experience aging populations in the next century because of declining birth and mortality rates. China will soon join their ranks. According to statistics, the aging of China's population will approach its peak by the middle of the next century, with the percentage of the people aged beyond 60 making up 27.4 percent of the total. That means one out of every four people will be elderly.
As for the issue of aging, its situation has been growing increasingly severe in spite of the fact most people are still ignorant of the problems it brings about. Firstly, with families becoming smaller and living pace escalating, it is even graver for families to care for aged members adequately. Secondly, aging causes a relative decline in working force in that fewer people have to support the increasing aged people. Consequently, the productivity of the whole society is affected to some extent. Thirdly and most importantly, the aging of population in China resulted from the successful implementation of family planning has not been synchronized with national economic progress.
The rapidity of the population's aging has made it more urgent for the adoption of countermeasures. No doubt they key is to build a solid economic foundation. Meanwhile, importance shall be attached to overall social progress by changing the backward situation in social security, welfare and service.
What's more, family care and community services shall also be encouraged.
