These more precise models can then be used to accurately describe changes occurring in a population and better predict future changes.

When resources become limiting, populations follow a logistic growth curve. The population of a species will level off at the carrying capacity of its environment.

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.
