The New Population Bomb—
The four Megatrends that will change the world

Article summary

A series of looming demographic trends will greatly affect international security in the 21st century. How policymakers adjust to these changes now will determine the course of global political and economic stability for years to come.

Forty-two years ago, the biologist Paul Ehrlich warned in The Population Bomb that mass starvation would strike in the 1970s and 1980s, with the world’s population growth outpacing the production of food and other critical resources. Thanks to innovations and efforts such as the “green revolution” in farming and the widespread adoption of family planning, Ehrlich’s worst fears did not come to pass. In fact, since the 1970s, global economic output has increased and fertility has fallen dramatically, especially in developing countries.

The United Nations Population Division now projects that global population growth will nearly halt by 2050.

By that date, the world’s population will have stabilized at 9.15 billion people, according to the “medium growth” variant of the UN’s authoritative population database World Population Prospects: The 2008 Revision. (Today’s global population is 6.83 billion.) Barring a cataclysmic climate crisis or a complete failure to recover from the current economic malaise, global economic output is expected to increase by 2 percent to 3 percent per year, meaning that global income will increase far more than population over the next four decades.

But 21st century international security will depend less on how many people inhabit the world than on how the global population is composed and distributed: where populations are declining and where they are growing, which countries are relatively older and which are more youthful, and how demographics will influence population movements across regions.

These elements are not well recognized or widely understood. A recent article in The Economist, for example, cheered the decline in global fertility without noting other vital demographic developments. Indeed, the same UN data cited by The Economist reveal four historic shifts that will fundamentally alter the world’s population over the next four decades: the relative demographic weight of the world’s developed countries will drop by nearly 25 percent, shifting economic power to the developing nations; the developed countries’ labor forces will substantially age and decline, constraining economic growth in the developed world and raising the demand for immigrant workers; most of the world’s expected population growth will increasingly be concentrated in today’s poorest, youngest and most heavily Muslim countries, which have a dangerous lack of quality education, capital and employment opportunities; and, for the first time in history, most of the world’s population will become urbanized, with the largest urban centers being in the world’s poorest countries, where policing, sanitation, and health care are often scarce.

Twenty-first century international security will depend less on how many people inhabit the world than on how the global population is composed and distributed.

Taken together, these trends will pose challenges every bit as alarming as those noted by Ehrlich. Coping with them will require nothing less than a major reconsideration of the world’s basic global governance structures.

Europe’s reversal of fortunes

At the beginning of the 18th century, approximately 20 percent of the world’s inhabitants lived in Europe (including Russia). Then, with the Industrial Revolution, Europe’s population boomed, and streams of European emigrants set off for the Americas. By the eve of World War I, Europe’s population had more than quadrupled. In 1913, Europe had more people than China, and the proportion of the world’s population living in Europe and the former European colonies of North America had risen to over 33 percent.

But this trend reversed after World War I, as basic health care and sanitation began to spread to poorer countries. In Asia, Africa and Latin America, people began to live longer, and birthrates remained high or fell only slowly. By 2003, the combined populations of Europe, the United States and Canada accounted for just 17 percent of the global population. In 2050, this figure is expected to be just 12 percent—far less than it was in 1700. (These projections, moreover, might even understate the reality because they reflect the “medium growth” projection of the UN forecasts, which assumes that the fertility rates of developing countries will decline while those of developed countries will increase. In fact, many developed countries show no evidence of increasing fertility rates.)

The West’s relative decline is even more dramatic if one also considers changes in income. The Industrial Revolution made Europeans not only more numerous than they had been but also considerably richer per capita than others worldwide. According to the economic historian Angus Maddison, Europe, the United States, and Canada together produced about 32 percent of the world’s gross domestic product (GDP) at the beginning of the 19th century. By 1950, that proportion had increased to a remarkable 68 percent of the world’s total output (adjusted to reflect purchasing power parity).

This trend, too, is headed for a sharp reversal. The proportion of global GDP produced by Europe, the United States and Canada fell from 68 percent in 1950 to 47 percent in 2003 and will decline even more steeply in the future. If the growth rate of per capita income (again, adjusted for purchasing power parity) between 2003 and 2050 remains as it was between 1973 and 2003—averaging 1.68 percent annually in Europe, the United States and Canada and 2.47 percent annually in the rest of the world—then the combined GDP of Europe, the United States and Canada will roughly double by 2050, whereas the GDP of the rest of the world will grow by a factor of five. The portion of global GDP produced by Europe, the United States and Canada in 2050 will then be less than 30 percent—smaller than it was in 1820.

These figures also imply that an overwhelming proportion of the world’s GDP growth between 2003 and 2050—nearly 80 percent—will occur outside of Europe, the United States and Canada. By the middle of this century, the global middle class—those capable of purchasing durable consumer products, such as cars, appliances and electronics—will increasingly be found in what is now considered the developing world. The World Bank has predicted that by 2030 the number of middle-class people in the developing world will be 1.2 billion—a rise of 200 percent since 2005. This means that the developing world’s middle class alone will be larger than the total populations of Europe, Japan and the United States combined.

From now on, therefore, the main driver of global economic expansion will be the economic growth of newly industrialized countries, such as Brazil, China, India, Indonesia, Mexico and Turkey.

Aging pains

Part of the reason developed countries will be less economically dynamic in the coming decades is that their populations will become substantially older. The European countries, Canada, the United States, Japan, South Korea and even China are aging at unprecedented rates. Today, the proportion of people aged 60 or older in China and South Korea is 12 percent to 15 percent. It is 15 percent to 22 percent in the European Union, Canada and the United States and 30 percent in Japan. With baby boomers aging and life expectancy increasing, these numbers will increase dramatically. In 2050, approximately 30 percent of Americans, Canadians, Chinese and Europeans will be over 60, as will more than 40 percent of Japanese and South Koreans.

Over the next decades, therefore, these countries will have increasingly large proportions of retirees and increasingly small proportions of workers. As workers born during the baby boom of 1945 to 1965 are retiring, they are not being replaced by a new cohort of citizens of prime working age (15 to 59 years old). Industrialized countries are experiencing a drop in their working-age populations that is even more severe than the overall slowdown in their population growth. South Korea represents the most extreme example. Even as its total population is projected to decline by almost 9 percent by 2050 (from 48.3 million to 44.1 million), the population of working-age South Koreans is expected to drop by 36 percent (from 32.9 million to 21.1 million), and the number of South Koreans aged 60 and older will increase by almost 150 percent (from 7.3 million to 18 million). By 2050, in other words, the entire working-age population will barely exceed the 60-and-older population. Although South Korea’s case is extreme, it represents an increasingly common fate for developed countries. Europe is expected to lose 24 percent of its prime working-age population (about 120 million workers) by 2050, and its 60-and-older population is expected to increase by 47 percent. In the United States, where higher fertility and more immigration are expected than in Europe, the working-age population will grow by 15 percent over the next four decades—a steep decline from its growth of 62 percent between 1950 and 2010. And by 2050, the United States’ 60-and-older population is expected to double.

All this will have a dramatic impact on economic growth, health care, and military strength in the developed world. The forces that fueled economic growth in industrialized countries during the second half of the 20th century—increased productivity because of better education, the movement of women into the labor force and innovations in technology—will all likely weaken in the coming decades. College enrollment boomed after World War II, a trend that is not likely to recur in the 21st century; the extensive movement of women into the labor force also was a one-time social change; and the technological change of the time resulted from innovators who created new products and leading-edge consumers who were willing to try them out—two groups that are thinning out as the industrialized world’s population ages.

Overall economic growth will also be hampered by a decline in the number of new consumers and new households. When developed countries’ labor forces were growing by 0.5 percent to 1.0 percent per year, as they did until 2005, even annual increases in real output per worker of just 1.7 percent meant that annual economic growth totaled 2.2 percent to 2.7 percent per year. But with the labor forces of many developed countries (such as Germany, Hungary, Japan, Russia and the Baltic states) now shrinking by 0.2 percent per year and those of other countries (including Austria, the Czech Republic, Denmark, Greece and Italy) growing by less than 0.2 percent per year, the same 1.7 percent increase in real output per worker yields only 1.5 percent to1.9-percent annual overall growth. Moreover, developed countries will be lucky to keep productivity growth at even that level; in many developed countries, productivity is more likely to decline as the population ages.

A further strain on industrialized economies will be rising medical costs: as populations age, they will demand more health care for longer periods of time. Public pension schemes for aging populations are already being reformed in various industrialized countries—often prompting heated debate. In theory, at least, pensions might be kept solvent by increasing the retirement age, raising taxes modestly and phasing out benefits for the wealthy. Regardless, the number of 80- and 90-year-olds—who are unlikely to work and highly likely to require nursing-home and other expensive care—will rise dramatically. And even if 60- and 70-year-olds remain active and employed, they will require procedures and medications—hip replacements, kidney transplants, blood-pressure treatments—to sustain their health in old age.

All this means that just as aging developed countries will have proportionally fewer workers, innovators and consumerist young households, a large portion of those countries’ remaining economic growth will have to be diverted to pay for the medical bills and pensions of their growing elderly populations. Basic services, meanwhile, will be increasingly costly because fewer young workers will be available for strenuous and labor-intensive jobs. Unfortunately, policymakers seldom reckon with these potentially disruptive effects of otherwise welcome developments, such as higher life expectancy.

(The article then discusses “Youth and Islam in the Developing World,” problems caused by the “Urban Sprawl” that is “exacerbating 21st-century risks,” before he recommends on “Defusing the Bomb” (the new population bomb, that is).

Defusing the bomb

Averting this century’s potential dangers will require sweeping measures. Three major global efforts defused the population bomb of Ehrlich’s day: a commitment by governments and nongovernmental organizations to control reproduction rates; agricultural advances, such as the green revolution and the spread of new technology; and a vast increase in international trade, which globalized markets and thus allowed developing countries to export foodstuffs in exchange for seeds, fertilizers and machinery, which in turn helped them boost production. But today’s population bomb is the product less of absolute growth in the world’s population than of changes in its age and distribution. Policymakers must therefore adapt today’s global governance institutions to the new realities of the aging of the industrialized world, the concentration of the world’s economic and population growth in developing countries and the increase in international immigration.

During the Cold War, Western strategists divided the world into a “First World,” of democratic industrialized countries; a “Second World,” of communist industrialized countries; and a “Third World,” of developing countries. These strategists focused chiefly on deterring or managing conflict between the First and the Second Worlds and on launching proxy wars and diplomatic initiatives to attract Third World countries into the First World’s camp. Since the end of the Cold War, strategists have largely abandoned this three-group division and have tended to believe either that the United States, as the sole superpower, would maintain a Pax Americana or that the world would become multipolar, with the United States, Europe and China playing major roles.

Unfortunately, because they ignore current global demographic trends, these views will be obsolete within a few decades. A better approach would be to consider a different three-world order, with a new First World of the aging industrialized nations of North America, Europe and Asia’s Pacific Rim (including Japan, Singapore, South Korea and Taiwan, as well as China after 2030, by which point the one-child policy will have produced significant aging); a Second World comprising fast-growing and economically dynamic countries with a healthy mix of young and old inhabitants (such as Brazil, Iran, Mexico, Thailand, Turkey and Vietnam, as well as China until 2030); and a Third World of fast-growing, very young and increasingly urbanized countries with poorer economies and often weak governments.

To cope with the instability that will likely arise from the new Third World’s urbanization, economic strife, lawlessness, and potential terrorist activity, the aging industrialized nations of the new First World must build effective alliances with the growing powers of the new Second World and together reach out to Third World nations. Second World powers will be pivotal in the 21st century not just because they will drive economic growth and consume technologies and other products engineered in the First World; they will also be central to international security and cooperation. The realities of religion, culture, and geographic proximity mean that any peaceful and productive engagement by the First World of Third World countries will have to include the open cooperation of Second World countries.

Strategists, therefore, must fundamentally reconsider the structure of various current global institutions.

The Group of 8, for example, will likely become obsolete as a body for making global economic policy. The Group of 20 is already becoming increasingly important, and this is less a short-term consequence of the ongoing global financial crisis than the beginning of the necessary recognition that Brazil, China, India, Indonesia, Mexico, Turkey and others are becoming global economic powers. International institutions will not retain their legitimacy if they exclude the world’s fastest-growing and most economically dynamic countries. It is essential, therefore, despite European concerns about the potential effects on immigration, to take steps such as admitting Turkey into the European Union. This would add youth and economic dynamism to the European Union—and would prove that Muslims are welcome to join Europeans as equals in shaping a free and prosperous future. On the other hand, excluding Turkey from the European Union could lead to hostility not only on the part of Turkish citizens, who are expected to number 100 million by 2050, but also on the part of Muslim populations worldwide.

North Atlantic Treaty Organization (NATO) must also adapt. The alliance today is composed almost entirely of countries with aging, shrinking populations and relatively slow-growing economies. It is oriented toward the Northern Hemisphere and holds on to a Cold War structure that cannot adequately respond to contemporary threats. The young and increasingly populous countries of Africa, the Middle East, Central Asia and South Asia could mobilize insurgents much more easily than NATO could mobilize the troops it would need if it were called on to stabilize those countries. Long-standing NATO members should, therefore—although it would require atypical creativity and flexibility—consider the logistical and demographic advantages of inviting into the alliance countries such as Brazil and Morocco, rather than countries such as Albania. That this seems far-fetched does not minimize the imperative that First World countries begin including large and strategic Second and Third World powers in formal international alliances.

Jack Goldstone then continues with specific suggestions on how to NATO can better help in the case of Afghanistan and what creative steps the aging industrialized to promote stability in their societies.
