This might be better suited to the hist board, idk.

If the world's growth rate is falling, why is the population increasing? Is it mostly because people are living longer?

this is it. the most brainlet post on all of /sci/. Pack it up everyone we're done here

I mean, it's pretty simple. Total population will increase as long as the birth rate is greater than the death rate.

As long as the "growth rate" is above 0 there is positive growth. Jeez

If you look closely enough, the chart is actually showing two IQ bell curves.

The one on the right is for the Western European population. The one on the right is for /sci/.

I meant left. This is why I'm a part of /sci/.

As Oprah said, "some people just need to die." And I'm not talking about what would bring the growth rate more in line with the population. I'm talking about OP.

1000 to the second power is still more than 2 to the power of 10.

You have taken calculus right? Notice how when the growth rate increases the population curves up while when the growth rate decreases the population curves down. Population is the integral of the growth rate.

Note that this isn't a strict relationship. It just so happens that other factors are mostly equal during most of this graph, excluding the very beginning of it. But the growth rate roughly matches the PDF while the population matches the CDF

Inertia. Younger generation making kids faster than old die off, even when they have less than 2 kids.
