Population Density
The ratio between the total population and the total land area, usually measured in persons per square kilometer.

A model that describes population growth over time as a country moves from a rural, agrarian society with high birth and death rates to an urban, industrial society with low birth and death rates.
Population Composition
The structure of a population in terms of age, sex, place of residence, literacy, occupation, and religion, providing insights into the social and economic status of a region.
