The Demographic Transition Model shows how a country’s population changes over time as it grows richer and more modern.
Imagine you’re in a big family. When everyone is poor, there are lots of babies, like when your parents had 5 kids! But not many people live to be old because they get sick or work hard all the time. So birth rates are high, and death rates are also high.
Now imagine you grow up, get a job, and move out of your parents’ house. You start using things like phones, medicine, and clean water. Because of this, fewer people die young, so death rates drop. But for a while, people still have many kids because they don’t know when their family will be rich enough to stop having babies.
Eventually, life gets really good, everyone has jobs, schools, and even cars! People start thinking, “I might not need 5 kids anymore.” So birth rates drop too, and the population grows more slowly, or maybe it even starts shrinking!
That’s how a country moves through different stages of growth and change. It's like watching your family go from having lots of cousins to just having a few friends, but everyone is happier!
Examples
- A country starts with many babies and deaths, but later has fewer of both as it gets richer.
- In a village, most children don’t live to be adults, but in the city, they do.
- People stop having lots of kids when they know their children will survive.
