The world’s population distribution is divided into 3 main groups

Population Distribution - the way people are spread out across the Earth’s surface

Population Density - the number of people who live within a given area (usually a square kilometre)

Densely populated areas are areas which have large numbers of people per km². These are areas where there are many advantages for the people such as warmer climate, fertile soil and flat land.

Sparsely populated areas are areas which have small numbers of people per km². These are areas where there are many disadvantages for the people such as extreme climates, infertile soil and lack of employment.

Birth rate is the amount of people who are born per 1000 of the population

Death rate is the amount of people who die per 1000 of the population

Migration is the movement of people from one area to another.

The Demographic Transition Model attempts to explain the cycles that a population can go through.
