The United Nations believe that if the old people in a country over the age of 60 are more than 10 percent or over 65years old of population for more than 7percent of the total number, then it is already belongs to an ageing population country. This problem is generated by population age structure, while the change depends on three factors: births, deaths and migration. The most important element determining the ageing population is the decline of fertility rate.[1] So far, in our country there are 144 million of classified old people, making 11percent population in total, and increasing at 3percent average annual rate. It is predicted that by 2020 China’s elderly population will reach 248million, accounting for 17.2percent in total, and after 2050, the data will jump to 30percent, getting into severe ageing stage. The ageing levels rise from 10percent to 30percent in just less than 50years, while Britain, France, the United States and other western industrialized countries of will take roughly 100years. [2] As a developing country with a large population, this rate is indeed staggering.
Impact
Ageing population is the product related to national economy, politics, culture and many other fields. It concerns the people’s livelihood and national sustainable development strategies of major social issue. In this paper I will discuss two main impacts related in economy and the whole
