On Tendency and Features of Population Aging in China

Population aging in China is now in a stage of rapid development. This paper firstly introduces ways of measuring population aging process in regions and analyses in detail the trends and characteristics of population aging in provinces. We think that the transition of age-construction shows diver-sity because it is pushed on at different speeds in different regions. And the region pattern of population aging process is also obvious in view of its developing trends. Middle and west China will gradually be the major pusher-on of population againg in China, so research on population aging ought to be focused on middle and west China. We should set up a system of countermeasures to enhance the economic sustainable development through bringing forth new ideas on old-age security.
