Why is a national population strategy needed, and what are its limits?

A national population strategy is like having a map for how many people should be in a country and how they should grow or shrink over time.

Imagine your toy box has exactly 20 toys, and you want to share them with your friends. If too many friends come over at once, there won’t be enough toys for everyone, some will have to wait their turn or even leave. A national population strategy helps grown-ups decide how many “friends” (people) should be in the country so that everyone has enough space, jobs, and things like schools and hospitals.

But this map isn’t perfect. Sometimes it can’t predict if a lot of people will move in or out suddenly, like if your friend’s family moves to town and brings more toys with them. The strategy might not account for all surprises, so sometimes the plan needs to be updated.

Also, if the map says there should be 10 friends at first, but suddenly everyone wants to stay forever, the toy box might get too crowded, that's one of the limits of a national population strategy. It helps guide growth, but it can’t control everything that happens in real life.
