This document defines key population concepts and factors that influence population growth. It explains that fertility, which is a woman's ability to give birth, influences birth rate and population growth. Fertility is impacted by education levels of women, government policies, and cultural factors. Mortality refers to the death rate, and migration involves movement across boundaries. The document also outlines different types of populations including growing, underpopulated, overpopulated, optimal, aging, young, and declining populations.
