Abstract: Based on the data of rural population census and economic development in 2000 and 2010 in China, this paper analyzes the regional differences of population aging in rural China by dynamic cluster method. From the two clustering results, it can be found that the rural areas of Beijing, Tianjin and Shanghai have been in the area of severe aging, while the rural areas in the more developed eastern areas have not changed much in heavy areas.The most notable changes are the underdeveloped central and western regions. In the central and western regions in 2000, many identities have not yet entered the aging population, but by 2010, they generally entered the aging population,and all belong to mild aging area.
