Note: Natural increase is produced from the excess of births over deaths.
Lesson Plan: The Demographic Transition, Activity One
3. People are NOT evenly distributed over the surface of the earth.

4. Most people live:• on plains in the middle
latitudes• by rivers.

A. Polar and Tundra areas—Too cold.
B. Tropics (near the equator). Too hot and wet.
C. Deserts-1/4 of the earth’s surface. Too dry
D. Mountains-too steep, rocky, cold, and soil is too thin
Did you know… • Approximately 240,000 people
are added to the daily? • Approximately 167 people are
added to world population every minute?
6. Why populations increase or decrease:
A. Improved medical careB. Changes in technology
—ex: improved water treatment and waste removal; increased food production; food processing and refrigeration; improved nutrition
C. Migration-people moving A. Emigration—
exiting/moving OUT of a country
B. Immigration—moving INTO a country
D. WarsE. Plagues-diseases
that kill a lot of people.
7. Overpopulation: more people in an area than the resources can support.
• Is an area over populated? Geographers/Experts look at: a. birth rates b. death rates
What does the History of Population look like?
• Population density over time
