Heterogenity in mortality dispersion in the developed countries


Dr. Hui Zheng, Department of Sociology
Rank at the time of award: Assistant Professor


This project intends to investigate historical changes in mortality rates and mortality dispersions over the past two centuries in 15 developed countries and examine the mechanisms that may account for these changes, including aging, epidemiologic transition, the intrinsic relationship between mortality rate and mortality dispersion, and reemerging infectious diseases. This project will contribute to the cutting-edge research in population and health: (1) whether there is a limit to human life span; (2) whether increasing health disparities is a universal phenomenon in the developed countries; and (3) why U.S. may be different from other developed countries with regard to the trends of mortality rate and mortality dispersion.
