Population Pyramids

From: http://hvg.heinemann.co.uk/login.aspx. An examination of world populations and birth rate patterns: for a country's population to remain constant the average birth-rate needs to be around two children per couple; if the birth-rate drops below two then the population numbers will start to decrease over time, nearly all countries in Europe have a birth rate below two; for a developing country, the population pyramid continues to grow, a developed country's population pyramid bulges in the middle before decreasing in size; in the baby boom years the birth rate was high, as this group gets older, but if there are less babies the population pyramid changes, so now we have an ageing population with fewer younger people to support them.

Two children per couple actually will decrease the population because there are deaths to disease, infertility, accidents and other issues. For growth at all you need at least more than two per couple.

I dont think we will ever run out of people. Negative population growth in develped countries means more job opportunities for those in under developed countries. this could improve overall standare of living because less people are competing for the same resources. Also if we have the resources to support current population we have them for a smaller population no matter there age. We simply have to come up with a better system for distributing those resources.
