DemoGraphics '96 is only the most recent version of the DemoGraphics software. The previous version - DemoGraphics '94 - was sold to more than 600 educators and scientists in 46 countries worldwide. Many of the users have spontaneously sent us comments and suggestions on the program or responded to our feedback form. Here is a small selection:

"I cannot say enough about how superb your program is. For studying change on the global and individual country scene it is first rate. The ability to watch change unfold over a 100 year period is unique and highly educational. ... Keep up the great work."
(John B. Mahaffie, Associate, Coates & Jarratt, Inc.; Washington, D.C. 20015, U.S.A.)

Many thanks."
(Ken Chew, Dept. of Environmental Analysis & Design, School of Social Ecology, University of California, Irvine, California, USA)
