The population of the world is unevenly distributed. The distribution of population is expressed in terms of density. The density is the ratio between the numbers of people in to the size of land.

Distribution of population of the world has been divided into three regions.

I. Area of high density: 

The three principal high density zones are: 

• Eastern, Southern and South – Eastern part of Asia. 
• North – Western part of Europe. 
• North – Eastern part of USA and South Eastern part of Canada.

II. Area of high density: 

The population moderately dense in tropical regions of the world and moist temperature cold desertes and high rain fall zones near the equator have very low density of population.

• Asia is the most populous continent. It accounts about ‘61 percent’ of the world population.
• Africa is second most populated continent with 13 percent. 
• Europe has 12 percent. 
• South America 8.5 percent. 
• Northern America 5 percent. 
• Oceania is the least – populated region which has 0.5 percent.
• Antarctica is uninhabited permanently.
