2009 Population Reference Bureau. All rights reserved. www.prb.org Contemporary World Population Issues All population growth is now in the poorest countries and areas. Very young age structures in developing countries guarantee this. The situation is most acute in sub-Saharan Africa. As essential as population projections are, their accuracy must be continuously monitored. Extreme aging will place enormous stress upon many industrialized countries economies and societies. Low fertility in developed countries presents South-North migration opportunities. Development is often impeded by a lack of reproductive rights. In many ways, population change in the U.S. is not very different from that of Europe.

Slide 9

2009 Population Reference Bureau. All rights reserved. www.prb.org How Are Projections Made? The United Nations assumes that birth rates will decline so that all developing countries will eventually average a European-like 1.85 children per woman. That assumption is entirely dependent upon the additional assumption that the use of family planning will rise to the same level as that in Europe and North America, which the UN is very careful to point out.
