The line chart given above reflects the phenomenon of the aging population in China.According to the figures,the percentage of those aged over 60 experienced a moderate increase from 6%of the total population in 1990 t0 15%in 2010 in China.It is predicted that the proportion will amount t0 25%in 2020 and 30%in 2030.China is one of the countries suffering from the aging population,which to a large degree is attributed to the social progress and economic development.However,this phenomenon will be likely to bring about some undesirable consequences in the future.On the one hand,the odds of having weak elderly parents-and all the attendant need for physical and financial assistance-have jumped eightfold in just one generation.On the other hand,an aging society means slower growth of population and thus a shrinking workforce,consequently,the productivity of the whole society will be affecLed to some extent.To conclude,such a trend will probably develop more dramatically in the future.Therefore,it is advised that administrators and the authorities should keep taking measures to solve the problem.
