GeoSim IntlPop allows students to model population growth and age distributions for selected countries and regions of the world. Population projections for each country can be simulated, and students may modify birth and death rates to investigate any resulting effects on the projected populations.
The applet requires features of the Java® 2 Platform. To run IntlPop on your browser, you must have the Java Plug-In installed. The plug-in is freely available from Sun's website, and most browsers will ask permission to download and install it automatically when you attempt to run the applet.
You can also download the entire package and run it locally from your machine as a Java application. This requires the Java Run-time Environment version 1.2 or later to be installed on your machine (which includes the Java Plug-In, for Win32 distributions). The distribution includes all the data files and web pages needed to install the applet on your own local web server. Simply unzip everything into one directory and read the ReadMe.txt file for instructions on running the application.
