Everyone is freaking out about this graph, showing that the world's population is going to peak soon and then start to decrease.
So this is true.
Demographers think that the world's population is going to peak around 10.9 billion before starting to decrease quite soon.
So today we're going to explain why the world's population is declining, why some people think this is the end of us, while others think this could be the best possible situation for humanity.
This is some of the most fascinating information I've learned in years, so let's get into it.
We first started recording population size in 4000 BC, when the Babylonians used birth and death census data to understand population size, to figure out how much food they needed to produce, and how to plan for the future.
In many ways, now we're still doing the same thing.
Current governments use census data, such as birth and death certificates, to understand their own population size and understand how much food, again, that they need.
But now, society is more complex, so we design income tax for future investments, plan infrastructure to keep our citizens healthy and happy, and organize healthcare and education around our population sizes.
Now, when we want to understand the whole Earth's population, we have to rely on overarching bodies like the UN.
