THE DEMOGRAPHIC TRANSISTION MODEL
The Demographic Transtion model shows how changes in BIRTH RATES and DEATH RATES affect population growth in countries at diffferent stages of development:
Birth rates are high due to lack of contraception.
Death rates are high due to poor diets and disease.
High infant mortality rate.

Population grows rapidly.
An example is: Egypt, India, Kenya.
Stage three-Late expanding:
