Population Distribution
The way people are spaced out across the earth's surface, which is highly uneven due to various geographical and economic factors.
Population Density
The ratio between the number of people and the size of the land, usually measured in persons per square kilometer.
Crude Birth Rate (CBR)
The number of live births occurring among the population of a given geographical area during a given year, per 1,000 mid-year total population of the given geographical area during the same year.
Demographic Transition Theory
A theory that describes population growth through distinct stages, moving from high birth and death rates to low birth and death rates as a society develops.
Push and Pull Factors
Push factors (like unemployment or poverty) drive people away from an area, while pull factors (like better jobs and education) attract them to a new location.

Frequently Asked Questions
What is the difference between population distribution and population density?
Population distribution refers to the pattern of where people live across a region, while population density measures how crowded an area is by calculating the number of people per square kilometer.
Why is population distribution uneven across the world?
It is uneven due to physical factors like climate, terrain, and water availability, as well as human factors like industrialization, urbanization, and job opportunities.
What are the main stages of Demographic Transition Theory?
The theory has three main stages: Stage 1 (high birth and death rates), Stage 2 (high birth rate and declining death rate leading to rapid growth), and Stage 3 (low birth and death rates with low population growth).
