My point was that fertility rates or birth rates have nothing to do with population growth, except for a longer or shorter time frames (doubling time). These rates ignore death rates. You need both in order to establish population growth or decline.[
Fertility rate is what I told you in post 16. That is exactly how it is used in the article, viz. the mean number of children born to each woman. I quote: " The total fertility rate is the average number of children a woman gives birth to in their lifetime"
Try to control this mental illness of yours and stop making shit up.
If death rates exceed birth rates the population will decline . If birth rates exceed death rates the population will grow, until it reaches unsustainable numbers. Then birth rates and fertility rates will reach a forced zero or we have a nice big war or a pandemic.
I appreciate your attention to detail. But in your zeal to correct me you miss the IMPORTANT point about the exponential function, which was the subject of my post.
In the long run, birth rates and death rates will reach zero, and it will do so by our choice or by nature's choice. That is the dilemma at hand!
