Where Are All the People?

One of the biggest issues facing humanity currently is the exponentially growing population, but where are all the people? I hear about this problem all the time, but I haven't felt or seen any population increases or anything that is supposed to go along with it. While living in America probably has much to do with not feeling the effects, i barley even hear about it. If all the people aren't here, where are they? The map seems to suggest that the majority live in India and China. But if India and China are supposedly suffering the effects of over population why do only good things come from those countries? We constantly heard about China developing and industrializing. Their economy is booming, we even have borrowed billions of dollars from them, their politics are strong, they seem to be cooping with any stress extremely well. India is not fairing as well as China, but for the second most populated country in the world, it is not displaying the tell-tale symptoms of over population. So if the two most over populated countries are doing fine, where will over population hurt us?
