GeoSim MigModel is an applet that provides a student with the means to develope and explore models relating to migration. The student selects factors that they think were significant to migration between states or counties in the United States during a selected decade. The student can then compare their model with the actual migration that occurred during that period.
The applet requires features of the Java® 2 Platform. In order to run 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 you if they can 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 set the applet up on your own local web server. Simply unzip everything into one directory and read the ReadMe.txt file for instructions on running the application.
