Age by Stage Modeling of Dynamic Heterogeneity Ph.D. Dissertation, Department of Biology, University of Miami, 2017 Cohort(s): NLSY79 Publisher: ProQuest Dissertations & Theses (PQDT) Keyword(s): Age and Ageing; Health and Retirement Study (HRS); Heterogeneity; Income Level; Marital Status; Mortality Permission to reprint the abstract has not been received from the publisher. Mortality modeling has come a long way since the demographer Benjamin Gompertz (1779-1865). We address populations where mortality is structured by the joint effects of age and state and individuals can change state at each age. Dynamic states are the most complex and interesting states to consider and we focus on three categories of states: being married or unmarried, being below or above a particular income threshold, or being in one of four income states. We examine how the transience of our particular states at each age drives the cohort dynamics such as the demographic structure and lifespan inequalities within the cohort. In each chapter we used two U.S. nationally representative data-sets (the Health and Retirement Survey RAND data-set, and the National Longitudinal Survey of Youth) to statistically estimate the probabilities of survival and transitions between states at each age with regression analysis. These probabilities were incorporated into discrete age and discrete state matrices. We examine age-specific state structure, the average remaining life expectancy, its variance, cohort simulations, dynamic heterogeneity and individual trajectories. |
