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 decisionmakers 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.
