Publisher's Note This user-friendly IBM-based book/disk package provides a sample of many of the powerful population programs currently available on the market.Each chapter contains a general introduction to demographic concepts and a series of projects are based on the software programs. The projects are presented in such a way as to illustrate the use of the software but allow instructors to make interpretations at different levels of complexity. What's more, the text and projects are level neutral; the basic set of demographic concepts is generally included at all levels of undergraduate and graduate studies.
