If you look at the RATE of change in population growth

it's been declining for a while now. It's also declining at a faster rate itself. If this trend continues (which numerous countries are set to wipe out their 6-10 for a 1-2 soon), then in 25 years or so, we'll be stagnant. The problem is that negative rates are nearly impossible to turn around. (Think of being told to bring a kid into this world during a war.)

While that doesn't sound bad, nor does the following reduction rate of 1.7 ish, what that means is that we could lose 15% of our population every 19 year generation. When you run that math, it puts us back under 500M in another 35 years.

Rates are using defined as being stagnant at 2.2 child being born per female to cover mortality.
