Unlock This CourseImagine your school canteen only has 100 seats, but 200 students turn up for lunch. Chaos! Now flip it only 20 students show up but the school has paid for 100 meals. Also a problem! Governments face a similar challenge with their countries. Too many people can strain resources, but too few people can cause economic problems. That's why some governments actively try to increase or decrease their population size using special policies.
Key Definitions:
When a country has too many people for its resources, you get: overcrowded cities, not enough food or clean water, high unemployment, pressure on hospitals and schools and environmental damage like deforestation and pollution. Countries in this situation often consider anti-natalist policies.
When a country doesn't have enough people, problems include: not enough workers to run the economy, fewer taxpayers to fund public services, an ageing population with too many elderly people and not enough young workers to support them. Countries facing this often use pro-natalist policies.
The world population hit 8 billion in November 2022. It took just 12 years to go from 7 billion to 8 billion. But in some wealthy countries like Japan and Germany, the population is actually shrinking. Different countries face very different population challenges!
Some countries encourage people to have more children
Some countries are worried that their population is getting too old or too small. When not enough babies are being born to replace the people who die, the population shrinks over time. This is called a declining population. Governments in this situation use pro-natalist policies basically, they try to make having children more attractive and affordable.
It might sound odd that a government would want more people, but there are very real economic reasons. A shrinking workforce means fewer people paying taxes, which means less money for hospitals, schools and pensions. An ageing population puts huge pressure on healthcare systems. Pro-natalist policies try to fix this by boosting the birth rate.
Governments offer cash payments or "baby bonuses" when a child is born. They may also offer tax breaks for families with children, meaning parents pay less tax.
Larger families may get priority access to social housing or subsidised rent, making it easier to afford a bigger home for more children.
Generous maternity and paternity leave allows parents to take paid time off work after having a baby, reducing the financial burden of childcare in the early months.
France has one of the most famous pro-natalist policies in the world. Worried about a falling birth rate after World War II, the French government introduced a package of incentives that continues today:
Result: France has one of the highest birth rates in Europe around 1.8 children per woman (the Total Fertility Rate). While still below the 2.1 replacement level, it is much higher than countries like Italy (1.2) or South Korea (0.7). France's policies are widely considered a relative success.
On the other side, some countries particularly in the developing world have faced rapid population growth that outstrips their resources. When the birth rate is very high and the death rate falls (thanks to better medicine), the population can explode. Governments in this situation use anti-natalist policies to slow things down.
Anti-natalist policies can range from gentle encouragement to very strict rules. They typically involve a mix of education, access to contraception and sometimes financial penalties or rewards.
Teaching people especially women about family planning, contraception and the benefits of smaller families. Educating girls and keeping them in school longer is one of the most effective ways to lower birth rates naturally.
Governments provide free or cheap contraception and family planning clinics. This gives people the choice to have fewer children without forcing them.
China's One Child Policy is the most famous and controversial anti-natalist policy in history. By 1979, China's population was approaching 1 billion and the government feared it would run out of food and resources.
What the policy involved:
Results:
In 2015, China scrapped the One Child Policy and replaced it with a Two Child Policy and then a Three Child Policy in 2021 effectively becoming pro-natalist as it now tries to boost its falling birth rate!
Let's put the two types of policy side by side so you can clearly see the differences and similarities.

France and China are the most famous examples, but many other countries have tried to manage their population size. Here are a few more worth knowing:
Japan has one of the world's lowest birth rates around 1.2 children per woman. The population is shrinking and ageing fast. The government offers generous child allowances and has tried to improve work-life balance so women feel they can have careers and children. However, cultural pressures and expensive city living mean the policies have had limited success so far. Japan is also reluctant to accept large numbers of immigrants to fill the gap.
India overtook China as the world's most populous country in 2023, with over 1.4 billion people. India has historically used family planning campaigns to reduce birth rates, including controversial sterilisation programmes in the 1970s. Today, India's approach focuses on education, women's empowerment and voluntary family planning rather than force. India's birth rate has fallen significantly from around 6 in 1960 to about 2.0 today largely due to better education for women.
One of the most powerful factors in reducing birth rates is simply educating girls. Research consistently shows that when girls stay in school longer, they marry later, have children later and have fewer children overall. This is often more effective than government policies alone. The United Nations considers girls' education a top priority for managing global population growth.
It's not enough to just describe policies in your exam, you'll need to evaluate them. That means weighing up the good and the bad.
In iGCSE Environmental Management exams, you might be asked to:
Always use named examples (like France or China) with specific facts and figures to get top marks!
Governments manage population size because having too many or too few people causes serious problems. Pro-natalist policies encourage more births through incentives like cash bonuses and free childcare France is the best example. Anti-natalist policies slow population growth through education, contraception and sometimes strict rules China's One Child Policy is the most famous (and controversial) example. Both types of policy have strengths and weaknesses and the best approach often combines government action with improving education, especially for women and girls.
