I can describe what happens in each stage of the
demographic transition model
In Stage 1 of the demographic transition model the birth rate and death rate are fluctuating and there
is no major increase or decrease of population. However in Stage 2 of the model, the death rate falls
rapidly and the birth rate stays the same and so there is a big population growth. In stage 3 of the
model, the birth rate falls and the death rate stays stable and so the population growth is slow. In the
last stage of the demographic transition model the death rate remains stable however the birth rate
fluctuates and this means that the population is increasing very slowly. The natural increase is the
birth rate minus the death rate.…read more

I can explain why infant mortality rates are high in poor
Infant mortality rates are high in poor countries because families do

there aren't enough health services to help the infant. Also in poorer
countries, people have more children and since they fend for all of them,
lots of the infants die.
I can explain why life expectancy is high in rich countries
Life expectancies are higher in rich countries because people have
more money for treatments and also they have enough money to spend
on resources to help them live longer. Also living conditions are better in
rich countries. Health treatment is more available and advanced in richer
countries and this increases people's life expectancies.…read more
