The demographic transition model helps explain how birth and death rates may change as a country develops. It is a general model rather than a fixed timetable. Pakistan contains regions and social groups at different stages because education, income, urbanisation and health services vary widely.
Learning outcomes
- Describe the stages of the demographic transition model.
- Relate social and economic change to fertility and mortality.
- Explain why national averages conceal regional differences.
- Assess policies that may reduce unsustainably rapid growth.
Stages of transition
In the first stage, birth and death rates are both high and population growth is slow. In the second stage, death rates fall because of improvements in food supply and public health, while birth rates remain high, so growth accelerates. In the third stage, birth rates begin to fall and growth slows. In a later stage, both rates are low.
Pakistan cannot be placed perfectly in one stage because fertility and mortality differ between urban and rural areas, provinces, income groups and levels of female education.

Education and fertility
Education can delay marriage, increase awareness of health and family planning and expand employment options. Female secondary education is especially influential because it raises decision-making power and the opportunity cost of leaving paid work for repeated childbearing.
Education works best with accessible health services, safe transport, legal protection and labour-market opportunities. School enrolment alone may not change behaviour if girls leave early or cannot work later.

Economic and social security factors
Where formal pensions and insurance are limited, parents may depend on adult children for old-age support. High infant mortality can also encourage more births. As incomes, child survival and social protection improve, families may choose fewer children and invest more in each child.
Housing costs and urban lifestyles can reduce family size, while migration may temporarily separate spouses or change expectations through exposure to different social norms.
Policy choices
Effective population policy is broader than distributing contraceptives. It includes girls education, maternal health, reproductive choice, later marriage, child survival, public information and reduction of poverty. Coercive measures may violate rights, create mistrust and produce unintended demographic effects.
Policies should be culturally informed, voluntary, affordable and integrated into primary health care.
Key terms
demographic transition • fertility decline • mortality decline • family planning • reproductive health • social protection • opportunity cost • regional variation
O Level examination guidance
- Use the model to explain processes, not to claim every country follows identical stages.
- Link female education to later marriage, employment and informed choice.
- For policy evaluation, discuss effectiveness, rights, access and cultural acceptance.
Review questions
- What happens in stage two of the demographic transition?
- Why may national averages be misleading?
- How can girls education reduce fertility?
- Why can improved child survival reduce family size?
- Why are coercive policies problematic?
Suggested answers
- Death rate falls while birth rate stays high, causing rapid growth.
- Different regions and social groups have different fertility, mortality and service access.
- It can delay marriage, improve knowledge and expand employment choices.
- Parents are more confident that children will survive to adulthood.
- They may violate rights, create mistrust and produce unintended outcomes.
