The science of epidemiology includes etiology (the study of the causes of disease) and investigation of disease transmission (mechanisms by which a disease is spread).

Evolution involves changes in the gene pool, while a population in Hardy-Weinberg equilibrium shows no change. Hence, populations are able to maintain a reservoir of variability so that if future conditions require it, the gene pool can change.

In the first graph, the marginal cost of offspring produced is decreasing (each additional offspring is less "expensive" than the average of all previous offspring) and the marginal cost of offspring forgone is increasing.

However, it is also possible (second graph) for the marginal cost of offspring produced to increase, and for the marginal cost of offspring forgone to decrease.

It examines demographic transitions across countries like Sri Lanka, and the effects of the U.S. baby boom. Despite a low Total Fertility Rate, baby boomers are affecting population dynamics, contributing to concerns about sustainability as projections suggest a rise to 9.

By determining the life span of individuals in a population and how many offspring they produce human demographers and ecologists can summarize key aspects of a population, such as average life span, generation time, and growth rate. This allows comparisons between different populations and species.
