Research on the Current Characteristics and Countermeasures of Population Aging-A Case Study of Linyi City

The seventh national census data in 2020 showed that China's population aged 60 and above reached 264 million.It is projected that this number will exceed 300 million during the 14th Five-Year Plan period,which indicates that China will enter the stage of moderate aging from mild aging.As population aging will be the basic national context in China for a long time,coping with population aging has been elevated to a national strategy.With the deepening of population aging in China,how the elderly share the fruits of reform and development,enjoy their twilight years,and how to ensure the seniors’access to elderly care,medical services,productive aging,education,and elderly happiness is a realistic issue of common concern to the society.Linyi City is a typical case,as it is the most populous city in Shandong Province and one of the prefecture-level cities with the largest number of elderly people in the country.This paper analyzes the general pattern and current characteristics of population aging in Linyi based on the data of the seventh national census of the city.Besides,it explores the impact of population aging on economic and social development.In doing so,the paper will provide effective references and constructive recommendations to deal with a series of problems that arise along with population aging,and promote the sustainable development of the city’s population,economy,resources,and environment.
