I've always wondered this! I thought it was probably relatively high, but 12% is pretty insane.

I had heard it was over 50% which i found very hard to believe so the 12% number seems a lot more reasonable.

Malthus wasn't wrong in principle, just in timescale. It's clear that technologies have improved Earth's human carrying capacity, but I don't know any method to claim that an S-shaped curve isn't inevitable.
It's sounds science fiction-ey, but I don't understand how you can see data like this and then defund NASA.

We use the world population and average life expectancy to calculate births in a year. To connect these point estimates at the varying times in history we use a bounded exponential growth model for births.
