This is a collection of 20 case studies prepared by a group of demographers; professors of economics, sociology, population studies, business, and marketing; and research analysts interested in understanding a world of changing demographics. Because the study of demography is becoming increasingly important to a growing number of professionals and decision makers in business and government, these case studies were written to address how the science of demography is being applied to real-world problems. Written in nontechnical language and presented in a classroom-tested format, this easy to use guidebook covers applications of applied demography in government planning, long term corporate strategy, forecasting, human resource management, and marketing. The authors show how to tie financial, political, and legal analysis into a consideration of demographic data and trends.
