We will solve exponential growth: A popular town in Idaho is growing at a rate of 4.5%/year. If the current population is 20,000, what will be the population in 20 years if this rate of growth continues?

Trump voted in AMZN $439, Trump voted out $3128 -> 4th root [$3128/$439]=1.63 -> 63%/year compounded annually
Obama voted in AMZN $44, Obama voted out $439 -> 8th root [$439/$44]= 1.33 -> 33%/year compounded annually.

the community where mothers start with their children later(Northern Europe, Singapore) ... huge production(...) above real demand ... high life expectancy ... will slow population decline. On the contrary, mothers from another community start with their children earlier(Niger, Chad) ... greater demand compared to lower production ... low life expectancy will slow down growth.
BUT when you force to equality or try to combine these worlds, "production" from the first world moves to the second ... so the growth of the population of the first world can slow below 0% and the growth of the second can accelerate above 4% for long times ... this can destroy nations or states or world. Growth in Africa is unnatural, it is artificially accelerated by reducing the mortality of irresponsible communities.
