This course examines the dynamics of human population distributions, densities, and growth patterns as they relate to population aging. The essential demographic processes of fertility, mortality, and mobility are addressed from multiple disciplinary perspectives, and topical coverage includes the environmental, social, political, economic, and cultural impacts on personal demographic behavior and population change. Emphasis is placed on historic and contemporary meanings and influences of population diversity, and how this diversity affects the patterns and consequences of aging across space and time.
