Population Growth
The world's population is growing rapidly. Between the years 1500 ­ 2000,

that affect the population size of the world, or a country.
When the birth rate is higher than the death rate, more people are being born than are dying.
Therefore the population grows ­ natural increase.
If the death rate is higher than the birth rate, it's known as natural decrease
The population size of a country is also affected by migration ­ the movement of people from one
area to another area.
Natural Increase = Birth rate ­ Death rate

Strategies to cope with an ageing population
1) Encouraging larger families, e.g. in Italy, women are offered cash rewards to have more children.
