Super-aging and social security for the most elderly in China.

This article is dedicated to an under-researched area, the demographic development and social welfare for the most elderly (aged ≥80 years) in The People's Republic of China. Based on national censuses conducted over the last six decades in China this study examined the development of the most elderly population in comparison with groups of younger elderly people. It is argued that population growth among the most elderly in China has occurred with unparalleled speed, a phenomenon referred to as second order aging. This study demonstrated that the proportion of individuals aged ≥80 years has increased more rapidly than any other age group among elderly people. Particular attention has been given to the issue of social security and social welfare for the most elderly based on the non-contributory old age allowances provided by various regions and provinces. A national unified program of social security for the most elderly in the population is still not in sight.
