Population growth

1/5

For a long time, the world’s population has been growing faster and faster. It reached 8 billion in 2022, compared to 2.5 billion in 1950. It will probably exceed 10 billion in 2050. Population growth started in Europe, thanks to advances in medicine, farming, and people living longer. Today, population growth is strongest in developing countries, especially in Africa.

Where people live on earth?

2/5

80% of humanity is concentrated on 16% of the earth's surface, and the large south-eastern part of Asia gathers more than half of the inhabitants! Other places, like deserts or mountains, have fewer inhabitants. Antarctica is even an uninhabited land. Sometimes, people even manage to settle in difficult areas, like mountains or jungles, by adapting the places to live there.

Big CHALLENGES

3/5

Because of this big growth, many people leave the countryside to live in cities, which makes the cities very large. In some countries, this creates slums, where people live in tough conditions. Population growth also creates inequalities because, in some places, it’s harder to get water, food, or electricity. Some countries tried to control the population growth, like China with its one child policy.

Wealth and Poverty

4/5

Wealth isn’t shared equally around the world: some countries are more developed and wealthier than others. Geographers use a tool called the Human Development Index (HDI) to see if a country is more or less developed. The HDI measures three important things: wealth, health, and education for people. This way, some countries are considered “highly developed” while others are developing or among the poorest.

Health & Education

5/5

Health and education vary a lot between countries. In some places, people don’t have access to hospitals or schools. This makes people more vulnerable in a crisis, like an epidemic. The United Nations (UN) and organizations work to help struggling countries and reduce poverty. For example, they aim to help more kids, especially girls, go to school.
