Yong Cai, PhD
Associate Professor Professor, Sociology, UNC Chapel Hill
caiyong@unc.edu
Cai’s research focuses on China’s one-child policy and its implications for fertility and social policies. Specifically, his work shows that: China’s fertility has dropped to a level well-below the replacement; the demographic impact of the one-child policy was modest, much less than the government’s claim of 400 million averted births; socioeconomic development played critical role in driving China’s fertility decline; and the socioeconomic impacts of low fertility and population aging are substantial. The consensus on these issues, to which Cai contributed, provided the empirical and scientific foundation that persuaded Chinese government to end the three-decades long policy.
