Few would contest the general proposition that the population factor bears directly on the course of the friendly — and sometimes unfriendly — competition between states in the world arena today. Problems arise, however, when we try to move from the general to the specific. How, exactly, do human numbers (population size, composition, and trends of change) affect the ability of governments to influence events beyond their borders — or affect the disposition of a country's interactions with outside actors? And this is no less important for the would-be strategist: How can we use population indicators to anticipate, with some reasonable hope of accuracy, the impact of yet-unfolding demographic forces on the balance of international power? This essay explores these questions for the world's largest strategic arena: the great Asian/Eurasian expanse.

3 Iran's latest Demographic and Health Survey placed the country's TFR at 2.17 in 2000. (Mohammad Jalal Abbasi-Shavazi, “Recent Changes and the Future of Fertility in Iran,” paper prepared for UNPD Expert Group Meeting on Completing the Fertility Transition, New York, March 11-14, 2002.) Vietnam's 2002 Demographic and Health Survey indicated that the country's TFR had dropped to 1.9.

4 The “old” literature on the social, economic, and political consequences of rapid population growth in low-income areas often betrayed a hardened Malthusian cast of mind. To cite one such study to exemplify the many: National Academy of Sciences, Office of the Foreign Secretary, Rapid Population Growth: Consequences and Policy Implications (Johns Hopkins University Press, 1971).
In retrospect, it is apparent that such thinking was highly alert to the possible stresses and problems presented by the demographic boom but exceedingly inattentive to the potential benefits and opportunities it might confer (not the least of these emanating from the health revolution that prompted these population explosions in the first place).
A new literature on the economic implications of population change in Asia is now beginning to emerge, one characterized by a more optimistic assessment of the influence of the region's demographic trends on prospects for material development. To exemplify the many with a single study once again: David Bloom, David Canning, and Jaypee Sevilla, The Demographic Dividend: A New Perspective on the Economic Consequences of Population Change (RAND, 2002). Unfortunately, it is not yet clear that this new tendency, though different in flavor, is free of the stifling idées fixes so characteristic of the literature it means to replace.
Newly fashionable arguments about the glowing possibilities of “demographic dividends” apparent in East Asian — or future South and Southeast Asian — trends in domestic “dependency ratios” (the proportion of older and younger citizens in relation to persons “of working age”) would seem, on their very face, to exaggerate the contribution of crude demographic structure to actual economic performance. The new “dividendism,” for example, proposes to credit much or even most of East Asia's dazzling growth record over the past several decades to its purportedly felicitous “dependency ratios” during the years in question — but neglects to explain why economic performance over that same period should have been so very disappointing for the countries of the Caribbean, even though the two areas exhibited quite similar levels and trends in the evolution of their “dependency ratios” from the mid-1960s to the present.
5 In 1975, of course, the Russian republic was embedded in the larger construct of the Soviet Union. Correspondingly, comparing population totals for Russia and Pakistan for that particular year is an exercise fraught with implicitly ahistorical assumptions. Nevertheless, these projections suggest that Russia's population total, which slightly exceeded Pakistan's as recently as 2000, will come to be only half as great as Pakistan's in just a quarter-century.

19 Part of these local, biologically impossible disparities could perhaps be attributed to differential migration or mortality patterns, but the numerical imbalance between boys and girls is too substantial to be explained away altogether.
