Mathematical demography is the centerpiece of quantitative social science. The founding works of this field from Roman times to the late Twentieth Century are collected here, in a new edition of a classic work by David R. Smith and Nathan Keyfitz. Commentaries by Smith and Keyfitz have been brought up to date and extended by Kenneth Wachter and Herve Le Bras, giving a synoptic picture of the leading achievements in formal population studies. Like the original collection, this new edition constitutes an indispensable source for students and scientists alike, and illustrates the deep roots and continuing vitality of mathematical demography.

This book is intended as a relatively nontechnica1 introduction to eurrent demographie methods. It has been several years in preparation, beginning from occasional class handouts I wrote to elaborate on essential points of demographie methodology. Its growth from scattered notes to an integrated text was a natural process, if a gradual one. The eontent of the book addresses three objectives. first, I have tried to avoid demographie methods that are now dated. In some ehapters, that has meant eoncentrating on formulas most demographers recognize. In the ehap ters on life tables, it meant testing competing formulas on a variety of real and synthetie data se.ts, and dropping or relegating to footnotes those that were least accurate. Second, I have attempted to give readers a sense of the limits of different formulas and methods. I am a terse writer, however, and for the reader that means most sentences carry weight. Chapters should be read attentively, with careful regard to commentary as weIl as to formulas and examples. Finally, I have tried to make the principal methodologies of the book accessible, by offering explanations for formulas that are not obvious, by keeping examples to the forefront, and by placing relatively specialized topics in ehapter appendices."

In the 50 years that have passed since Alfred Latka's death in 1949 his position as the father of mathematical demography has been secure. With his first demographic papers in 1907 and 1911 (the latter co authored with F. R. Sharpe) he laid the foundations for stable population theory, and over the next decades both largely completed it and found convenient mathematical approximations that gave it practical applica tions. Since his time, the field has moved in several directions he did not foresee, but in the main it is still his. Despite Latka's stature, however, the reader still needs to hunt through the old journals to locate his principal works. As yet no exten sive collections of his papers are in print, and for his part he never as sembled his contributions into a single volume in English. He did so in French, in the two part Theorie Analytique des Associations Biologiques (1934, 1939). Drawing on his Elements of Physical Biology (1925) and most of his mathematical papers, Latka offered French readers insights into his biological thought and a concise and mathematically accessible summary of what he called recent contributions in demographic analy sis. We would be accurate in also calling it Latka's contributions in demographic analysis."

The security environment in the aftermath of the Cold War has been challenging. Despite its emergence as the world's lone Superpower, options for the US to exercise its global influence through forward basing are becoming increasingly difficult. Major US military installations overseas have closed for a variety of economic, political, as well as strategic reasons. Even the US bases that remain may at times be politically undesirable to use or operationally restricted. Furthermore, US land-based forces are vulnerable and virtually targets at all times for kinetic and non-kinetic weapons. The realities of decreased access and increased vulnerability have given new emphasis to the concept of sea basing. This paper advocates the emerging concept and capabilities of sea basing. As such, it builds a case to support the claim that sea basing should be vigorously pursued. Analysis includes discussions on what constitutes sea basing; the primary security challenges which are driving its development; how sea basing can effectively address these situations; possible alternatives; and finally, recommendations on how to proceed with sea basing. Research of the sea basing concept was conducted via a literature review of US Navy vision documents, resent Defense Department reports and articles in military professional journals. While most of the literature discussed both the strengths and limitations of sea basing, the overwhelming majority of the documents endorsed the concept. To this end, the paper concludes that the sea basing concept represents the key to joint operational independence in the challenging political and security environments of the future.
