Worked Solution & Example Answer:The Demographic Transition Model above shows population change over time - Junior Cycle Geography - Question 3D - 2017
Step 1
State two reasons why the death rate is fluctuating in Stage 1.
Answer
One reason for the fluctuation in the death rate during Stage 1 is the prevalence of famine. Periodic food shortages can lead to a significant increase in mortality rates.
Another reason is the occurrence of disease outbreaks. In Stage 1, access to healthcare is limited, which means that diseases can spread rapidly, leading to a higher death rate.
Step 2
Explain one reason why total population is increasing rapidly in Stage 2.
Answer
Total population is increasing rapidly in Stage 2 primarily due to improvements in healthcare. Medical advancements reduce mortality rates significantly, particularly among infants and children, resulting in a net increase in population as the birth rate remains high.
Step 3
Explain one reason why birth rates are declining in Stage 4.
Answer
In Stage 4, birth rates are declining due to changing societal norms regarding family size and women's status. As women gain more access to education and careers, they tend to marry later and choose to have fewer children, which leads to a decline in the birth rate.
