Population by Region
World Population Distribution by Region, 1800–2050
Population Facts The first billion took from the dawn of
humanity until 1830. The second billion took only 100 years --
from 1830 to 1930. Three billion more arrived in the next 60
years. The next billion will take only 13 years
(yes, just 13 years!) Every second 5 people are born and 2
people die, a net gain of 3 people The world’s population is growing by
200,000 people a day.
Population Distribution:(Where people live)
90 % of the World’s population is in the northern hemisphere.
50% live in cities. 50% lives in Asia, it is about 20% of earth’s land area.
Population Density Earth’s population is 7 billion Earth's total area is 197 million square miles. MATH TIME!!!! Soo… what is our world
population density? World Population density is 34.5 per sq. mile Mumbai-29,650 people/sq. mile India- Most Dense Country in the World Mongolia – least dense country---
• has only about 4 people/ sq. mile U.S. has about 81 people/ sq. mile Missouri 85.3 people/sq mile
Movement Internal Migration: Movement within a country.
• Urbanization: movement from farms and villages to cities.

13% (220 million) in 1900 to 29% (732 million) in 1950 to 49% (3.2 billion) in 2005.
The projected figure is likely to rise to 60% (4.9 billion) by 2030
