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.
Global Population Growth Is Almost Entirely Concentratedin the World's Poorer Countries Billions Global Population: 1900 = 1.6 Billion 2000 = 6.1 Billion 2011 = 7 Billion World Population (in Billions): 1950-2050 Developing Countries Developed Countries United Nations Population Division, World Population Prospects, The 2008 Revision.

The Total Fertility Rate (TFR)Indice synthétique de fécondité (ISF) The TFR is the average number of children a woman would bear in her lifetime if the birth rate of a particular year were to remain constant.
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.
