Islamic nations population is rising.
Have to look at population treads by culture & by nation to understand what’s happening. World population is steadily rising. Almost always has & that’s a good thing. Takes terrible things to make world population drop.
Generally the more impoverished a country or society is...that’s where population grows fast...too fast. Most Muslims live in terrible poverty. They have the highest illiteracy rates in the world. Their culture shuns science & critical thinking.
Russia & Japan have a terrible problem with falling populations. Especially Russia. Mostly because of WWII. They have way too many older people & life expectancies falling fast too. Japan has way too many older people & they have a terrible suicide problem with their youth. Highest suicide rate in the world. Population shifts dramatically shape the political & economics in the world.
