Developed as an online exhibit at the Museum National d'Histoire Naturelle in Paris, France, this fascinating Website provides a wonderful introduction to human population growth, using interactive (Shockwave) media to engage the viewer in a learning game. Available in English or French, 6 Billion Human Beings leads visitors through interesting facts (daily statistics on fertility rates, death rates, etc.) and uses their interactive answers (e.g., age) to generate statistics on certain population dynamics (e.g., birth rate). Also provided are numerous statistics for different global populations and thought-provoking questions about the future. This is an excellent site and could serve well as a teaching tool for an undergraduate course in population dynamics or introductory statistics.
