Population Dynamics and the Demographic Transition Model

The video explores global population trends, highlighting the shift from concerns of overpopulation to declining fertility rates in some regions. It introduces the demographic transition model, detailing its five stages and their impact on population growth. The video also covers the epidemiologic transition model, explaining how causes of death evolve through different stages of societal development.
