IntlPop and HumPop


IntlPop is a population change simulation program. Factors such as Birth Rate, Life Expectancy, and Migration Rate affect population growth. IntlPop allows you to manipulate these variables and simulate population growth based on your values. Intlpop can be installed and run without Humpop.

Now available: IntlPop 3.0. As of 2014, we have replaced our earlier Java Applet version of IntlPop with a fully Internet-compatible (that is, HTML5/JavaScript) implementation. In the process, we updated the maps and data to 2010 information.

IntlPop 3 is distributed under the MIT open source license, and is free to use. A copy of the sourcecode for Intlpop 3 is available through GitHub here.


HumPop is a multimedia tutorial program. HumPop introduces and illustrates population concepts and issues. Users unfamiliar with such concepts should follow the tutorial before running simulations with IntlPop. HumPop will allow you to run IntlPop from within it be pressing the BEGIN SIMULATION button. We recommend that you install IntlPop with HumPop, but HumPop will run without IntlPop.
