The content of this site is easily understood by students in introductory science courses. The material accurately shows the impacts of factors such as education to fertility. The graphics are easily understood and greatly enhance the site. The site is an excellent tutorial for introductory general biology or environmental science classes that discuss trends in human population, although it would probably find application in many other disciplines.
The program runs without any problems and the graphics are small enough so that there is not a significant amount of delay over a 56K modem.
