Demographic projections are like guessing how many people will be playing in your favorite game next year, or even 10 years from now.
Imagine you and your friends start a club. Every year, some new kids join, and some leave to go to other clubs. If you want to know how many snacks you’ll need for the next big party, you might try to predict how many people will be there, that’s like making a demographic projection!
How it works
Why it matters
If you know how many people will be in your town, or even your school, you can plan better. You might need more buses, more playgrounds, or more pizza for lunch!
Examples
- A town uses demographic projections to know how many new schools they might need in the next ten years.
- Demographers predict that a country’s elderly population will double by 2040, helping planners prepare for more healthcare needs.
- A city projects its population growth to decide how much money should be budgeted for public transport.
