DEMOGRAPHIC CHARACTERISTICS
Population unevenly distributed with
All countries in region have a positive rate of natural population change.
very densely populated areas
very sparsely populated areas.

Stationary Growth (No Growth)
Slow Growth
Moderate Growth

Very Rapid Growth
Explosive Growth ( Population explosion) OR Population Bomb
Two demographic worldsLess-developed counties represent 80% of the world population, but more than 90% of projected growthRicher countries tend to have negative growth rates.

DEMOGRAPHIC TRANSITION 3 TYPES
1. Old balance Fertility Mortality
2. New balance Fertility Mortality
3. ImbalanceFertility Mortality

Note that in English, fertility refers to actual births.
Fecundity refers to the biological ability to have children (the opposite of sterility).

Dependency Ratio
The dependency ratio tells us how many young people (under 16) and older people (over 64) depend on people of working age (16 to 64). The dependency ratio is worked out with this formula.
Dependency Ratio = % under 15 + % over 65 ys: X 100 % between 15 & 64
A worked example should make this clearer. Pakistan, which is a developing country, has 41% of its population less than 15, and 4% over 65. This makes 55% (100 - (41+4)) between the ages of 15 and 64.
Dependency Ratio = 41 + 4 X 100 = 81.8 55
