The fertility index is the average number of children women will have. Obviously men don't give birth.
So it can be understood as the number of children per couple.
100 people means 50 women, with a fertility index of 0.8, giving 40 children.
This new generation of 40 = 20 couples = 16 children.
Etc.
The minimum fertility index for population maintenance without war or disaster is 2.1. ( slightly more males are born, some people die before reproducing, or are sterile, so it can't be 2.0 ).
Whites are well-below that everywhere. A few White ultra-conservative religious groups still have high fertility ( Amish and some conservative Menonites, ethnic Germans ), but they can't compensate for the infertility of other White ethnicities.
Iceland was among the last White coutries to fall below replacement ( the current adult generation pulled the average below ). Elsewhere we are 2, 3, or 4 generations below replacement.
.81 replacement rate calculates to 40 children, not 81?
0.81 is the fertility index of South Korea.

Oh wow, OK, that's horrific. I didn't realize SK was so far behind the curve. I question why nobody is flipping out about this over there
Your example above was a fantastic way to visualize things. Being able to contextualize numbers is a wonderful talent. Thanks.
