Why Is Most Of Humanity Concentrated In India And China?

Most of Humanity is in India and China because the ratio of human survival and occupation of the planet has always been similar, but modern advancements have allowed those numbers to increase exponentially, so the difference has become more obvious. After the initial spread of humanity from Africa, China and India proved to be two of the most hospitable places for hunting, gathering, agriculture, and survival, mainly due to climatic conditions and available crop selection. With more availability for agriculture and healthy life, survival rates were higher, while more space and food meant that more babies could be born. 1,000 years ago, Asia definitely had more people, but there were only about a hundred million more than people in the rest of the world. Babies were born all over the world, and mortality rates were relatively similar; many people did not survive even to childbearing age, which "kept the world's population in check." The inability to mass-produce food also made larger populations less viable. Moreover, it is important to remember that wars and epidemics would have had much longer and larger effects in the past. The number of people was so much smaller, life was so much shorter, and birth conditions were scarce in many parts of the world.
