Picture this: all over the world, from bustling cities to sleepy towns, something weird is happening. We're seeing fewer and fewer young faces. Itâs like the world is slowly running out of kids. This quiet little trend has a big name: global population decline.
For most of history, humanity's population grew at a snail's pace, held back by the big three buzzkills: disease, famine, and war. Then, BOOM! The industrial revolution kicked in, and our population went through the roof. We were multiplying like rabbits! But just as we were getting used to the crowd, people quietly decided to pump the brakes on making more people.
So, hereâs the magic number: two. For a country to keep its numbers stable, every couple needs to have about two kids. But what happens when the average drops to one, or even less? Things get weird, fast. Imagine a society where 100 people today only have 40 kids, who then have 16. Itâs a real-life shrinking machine! This isn't just about empty playgrounds; it's a social earthquake in the making. So, what exactly happens when a country starts to run out of young people, and is your country next on the list?
