Analysis on the age structure of minority population in China: based on the theory of stable population
(2.Institute of Population and Labor Economics, Chinese Academy of Social Sciences)
【Abstract】Based on the theory of stable population, this paper uses census data to analyze the age structure of minority population in China. The study shows that, compared with Han ethnic group, whose benchmark ratio has declined dramatically to below 1.0, the benchmark ratio of minority population is still above 1.0. There is an enlarging gap between the benchmark ratios of different minorities, and the variation increases over time. Although the age structure of minority population still belongs to the growth type, its development process is lagged behind Han ethnic group by about 10 years. Among the minorities with population over one million, six of them have changed population age structure into the stable or decreasing type. Although the population momentum of minorities is much larger than that of Han ethnic group, it assumes a downward trend over time as well, in spite of its fluctuations sometimes. Viewing from the population age structure, Han, Korean and Manchu ethnic groups will have very serious challenges of rapid population decline. Other minorities have begun the process of population transition as well, albeit at different stages at present. They will be unavoidably on the path toward low fertility as Han ethnic group already did.
