PRB’s 2012 World Population Data Sheet
›“The most rapid population growth in many ways [occurs in] the countries that can least afford it,” said Carl Haub in a webinar on July 19 to launch the Population Reference Bureau’s (PRB) 50th annual World Population Data Sheet. This year, the report explores aging populations in more developed countries, rapid population growth in less developed countries, and the increased global prevalence of non-communicable diseases in an interactive map, which concisely illustrates global trends. PRB estimates that the world’s population is 7,057,075,000 as of mid-2012; the global population crossed the seven billion threshold in October 2011.
“The most rapid population growth in many ways [occurs in] the countries that can least afford it,” said Carl Haub in a webinar on July 19 to launch the Population Reference Bureau’s (PRB) 50th annual World Population Data Sheet. This year, the report explores aging populations in more developed countries, rapid population growth in less developed countries, and the increased global prevalence of non-communicable diseases in an interactive map, which concisely illustrates global trends. PRB estimates that the world’s population is 7,057,075,000 as of mid-2012; the global population crossed the seven billion threshold in October 2011.
Aging Europe and East Asia
Haub explained that population growth in Europe has been declining since the 1970s and is more or less a “pre-programmed destiny” for these countries. People of child-bearing ages make up a smaller percent of the population in many more developed countries, so unless there is an “enormous increase” in total fertility rates, these populations will continue to decline for the foreseeable future.
Haub noted that these aging populations are unprecedented. In Germany and Italy, for example, 21 percent are over the age of 65; many other European countries have similar figures, as do other developed countries like Japan and South Korea. PRB expects these percentages to increase throughout the next century and for European countries to struggle to support greater numbers of retirees.
Many such states have already found it difficult to raise the retirement age, even though medical advances allow people to work until later ages. PRB projects that in Japan, 42 percent of their population will be over the age of 60 in 2050; if such a large percentage of the population is no longer in the labor force, it will be difficult for to find the resources to support them.
The report shows that the United States, on the other hand, is still experiencing modest population growth. The higher birthrate is in part due to immigration, as recent immigrants to the United States tend to have more children. Haub noted that European states have been reluctant to accept greater numbers of migrants to try to reverse their declining population.
Youthful Developing Countries
While the demographic destiny of aging countries is somewhat determined, the future for less developed countries is more uncertain. Many countries in sub-Saharan Africa, the Middle East, and South Asia have large and growing youth populations, and how many children these “future parents” will have is uncertain. That uncertainty is underscored by the variety of scenarios for future population growth. The UN has four variants – high, medium, low, and constant fertility – which vary considerably in their projections for future populations, and PRB’s global projections for 2050 are some 600 million people more than the commonly-used medium variant UN projection.
Rapid growth in the least developed countries is hardly a new phenomenon, but PRB breaks down the numbers to an impressive degree. The 2012 Data Sheet provides updated net migration rates, projected population as a multiple of today’s, infant mortality rates, rate of natural increase, and other basic statistics. PRB also provides population pyramids from the wealthiest and poorest quintiles of the population of Malawi, as an example of the utility of desegregating data to better allocate resources to the underserved. They found that while birthrates have begun to decline for the wealthiest one-fifth of Malawians, the poorest citizens still have a total fertility rate of over seven children per woman.
Measuring Health Systems
Devastating infectious diseases – malaria, tuberculosis, and HIV/AIDS – have long been entrenched in some of the least developed and most rapidly growing parts of the world. But this year, PRB began to assess health on a broader level by tracking deaths attributed to non-communicable diseases as well. Diseases like cardiovascular disease, diabetes, respiratory illness, and cancer are leading causes of death in developed countries, but they have also increased in prevalence in developing countries at an alarming rate.
PRB is not the only organization to take note of the change in disease predominance. The World Health Organization has issued guidelines targeting four factors which increase the risk of these illnesses: tobacco use, alcohol abuse, poor diet/obesity, and physical inactivity. The UN also called a special session last September to discuss non-communicable diseases. President of PRB Wendy Baldwin noted that the last such discussion on a health issue was 10 years ago about HIV/AIDS.
Baldwin also pointed out that non-communicable diseases can increase the burden on the health systems of developing countries even more so than in developed states. She reported that in south Asia, for example, people have heart attacks on average six years earlier than people in developed countries, meaning more families lose their primary breadwinners.
The Data Sheet Over Time
The World Population Data Sheet has long been a vital resource for those in the population, health, and environment fields and has grown to include far more data than its first iteration in 1962. At first, the sheet had only four indicators: a population estimate for the year, annual rate of increase, crude birth rate, and crude death rate. Over time, PRB began measuring a greater number of key figures like infant mortality and life expectancy at birth. Population projections, a staple of the current version, were not added until 1978, perhaps in response to the inception of the United Nations World Population Projections in 1974.
Over the past five decades, the data sheet has been witness to some major shifts in global population trends. While PRB discourages researchers from comparing past data to current figures because the measures and methods of gathering information have likely changed over time, it is still possible to see the rise of importance in several trends based on the indicators PRB chose to focus on each year. For example, extremely young populations have been found to have profound effects on a country’s stability and prosperity, as have aging populations. The 1966 data sheet was the first to measure the percentage of the population under the age of 15, and it didn’t become a consistent data point until 1977.
The number of people living in cities in the developing world surpassed those in the developed in 1970, according to the UN, and in 1972, PRB began tracking the percentage of populations living in urban areas. HIV/AIDS indicators were added in 2000, as global awareness and a commitment to fighting the disease was rising.
PRB’s demonstrated commitment to continually adding more data and refining existing projections makes the data sheet is a valuable resource to those studying the problems of today and the future. Fifty years on, the amount of information collected is staggering. The data sheet provides a glimpse at not just how many people there are in the world, but also where and how they live.

Iran’s Surprising and Shortsighted Shift on Family Planning
›August 8, 2012 // By Elizabeth Leahy MadsenIn late July, Iran’s government announced that it would no longer fund family planning programs, a dramatic reversal following 20 years of support. The change is especially abrupt for a country that has been lauded as a family planning success story, with thorough rural health services and an educated female population contributing to one of the swiftest demographic transitions in history.

Three UN Millennium Development Targets Reached and a Review of the Human Drivers of Climate Change
›“It is plausible that key transitions in human evolutionary history have been driven in large part by climate change,” write Eugene A. Rosa and Thomas Dietz in “Human Drivers of National Greenhouse-Gas Emissions,” a literature review published by Nature Climate Change. “Changes in climate will doubtless be a key force in the future evolution of social systems, including all aspects of social, economic, and political life, while impinging on the health and well-being of the individuals who populate them.” Rosa and Dietz cite numerous studies to argue that nearly every facet of society will be affected by climate change. “The critical point,” they write, “is that population, affluence, technology, and all other drivers act not alone or additively but in a multiplicative fashion.” For example, rapid population growth can lead to an increase in urbanization, which generates “substantial demand for goods and services that can induce emissions in distant places.” They conclude that huge changes must be made in technology and consumption in order to combat the effects of climate change that are being caused by a growing population and an increasingly affluent world.
The United Nations’ 2012 Millennium Development Goals Report, released last month in New York City, announces that three of the eight major human development goals have been reached ahead of their 2015 targets. The Millennium Development Goals, set at a conference in 2000, were established to “uphold the principles of human dignity, equality, and equity at a global level.” The 2012 report indicates that the number of people living in extreme poverty has been halved since 1990; the proportion of people in the world without sustainable access to safe drinking water has also been halved; and more than 200 million slum dwellers have “gained access to either improved water sources, improved sanitation facilities, or durable or less crowded housing.” At the report launch, UN Secretary-General Ban Ki-moon noted that “these results represent a tremendous reduction in human suffering and are a clear validation of the approach embodied in the MDGs, but they are not a reason to relax.” Goals that have yet to be achieved include universal primary education; gender equality; reduced child mortality and improved maternal health; reducing rates of diseases such as HIV and malaria; and creating a global partnership for development.

Is This What Climate Change Feels Like? Geoff Dabelko on ‘CONTEXT’
›“I think that the conditions that we’re experience now are ones that track with what we expect to see more of; so dry places getting drier, wet places getting wetter, and more extremes in terms of variability of the weather,” said ECSP Director Geoff Dabelko in the latest installment of CONTEXT, a weekly Wilson Center interview series. While it’s difficult to link the current drought – or any one weather or climate event – directly to man-made climate change, Dabelko said that “the warming trends that we’re seeing and anticipating with climate change suggests that this is a preview of what may be to come.”

A Roundup of the ‘Global Trends 2030’ Series on Population Aging
›The National Intelligence Council is trying something new for this year’s Global Trends report: keeping a blog. So far, there have been postings from analysts and contributors on everything from migration and urbanization to international banking and precision strike capabilities, but over the past week, one of the most extensive series yet went up on demography. Though youth bulge theories have often dominated population-related security discussions, 11 posts highlight the newest and least understood of all demographic conditions: advanced population aging.
In parts of the world, mainly Europe and several countries in East Asia, populations are set to become “extremely mature” because of sustained declines in average fertility to very low levels and steady increases in lifespan. Demographers measure maturity by a population’s median age – the age of the person for whom precisely half of the population is younger and half older. Japan and Germany currently have the most mature populations; both are reported to have a median age slightly over 45 years. By 2030, UN Population Division and U.S. Census Bureau projections suggest that there may be between 19 and 29 countries that pass this benchmark. In Japan, the median age is projected to be 51.
If 5 out of 10 people in a country over 50 years old sounds unprecedented, that’s because it is. In this series, titled “Population Aging to 2030,” a group of political demographers, economic demographers, political scientists, and historians discuss the implications of this never-before-experienced set of age structures.
In his introductory essay, “Population Aging: A Demographic and Geographic Overview” (cross-posted here on New Security Beat), Richard Cincotta outlines the upcoming demographic trend, identifying the particulars of these novel age structures and indicating the regions that are expected to mature into economically and politically advantageous and disadvantageous demographic profiles.
In “Population Aging – More Security or Less?,” Jack Goldstone examines the effects on the U.S. military of a maturing developed world. With the United States and their traditional allies having proportionally fewer young people, will this impact limit their ability to put “boots on the ground?” Can new partnerships be developed in order to make up for this shortfall in man power?
In “China: the Problem of Premature Aging,” Richard Jackson focuses on China’s unique set of aging issues. Due to strict immigration laws and the one-child policy, China is experiencing the most rapid aging of the major powers. The favorable age structure which has enabled huge economic growth will soon shift to being a major burden on a relatively smaller working-age population, having potential political and societal consequences beyond that.
“The Sun Has Yet to Set on China” provides a different interpretation of the challenges China faces. Jennifer Dabbs Sciubba argues that although there will be changes in age structure, the problems may be overstated and the United States may still face a challenge to its status as sole global superpower.
In “Population Aging and the Welfare State in Europe,” Ronald Lee and Andrew Mason emphasize the stresses aging will exert on the extensive social welfare programs of many European states. The combination of longer life expectancy and declining fertility rates has led to a large and increasing funding gap in the welfare system, leaving questions as to the future viability of these programs.
In “Population Aging and the Future of NATO,” Mark Haas foresees that the welfare funding gap could have far-reaching international security consequences. With European governments diverting more and more resources away from military spending to fund welfare programs, the current U.S. irritation with NATO is likely to continue, as European allies “free ride” on the back of U.S. military supremacy in order to cut their defense budgets.
In “The Beginning of History: Advanced Aging and the Liberalness of Democracies,” Richard Cincotta examines the future of the liberal democratic political systems across aging countries. With increasing pressure on resources and a large disparity likely between the native born and migrant populations, it may become challenging for these states to remain liberal and democratic.
For Toshi Yoshihara, author of “The Strategic Implications of Japan’s Demographic Decline,” the aging process will pose a question of priorities for the leaders of Japan. The decreasing number of personnel available to the military, the effects of which were highlighted by the recent tsunami, will force a strategic decision between a defense force that is prepared primarily to address immediate and local security threats or one that is trained primarily for broader humanitarian interests.
“A Demographic Sketch of a Reunified Korea” provides interesting insights into the hypothetical demography of a single, unified Korea. Putting aside the two very distinct social paths that evolved during the past 60 year, Elizabeth Hervey Stephen uses demographic projections to envisage the challenges and opportunities that could arise from reunification.
David Coleman points to immigration as a possibly-mitigating force to aging in the developed world. In “The Impact of Immigration on the Populations of the Developed World and Their Ethnic Composition,” Coleman concludes that the developed world is likely to become “super diverse” by 2030. But this trend can be volatile. International migration is subject to many political and economic factors, bringing into question whether the developed world can rely on migration to supplement their native growth rates.
In “The Ethnic Future of Western Europe to 2030,” which wraps up the series, Eric Kaufmann examines the ethnic make-up of Western Europe in the coming decades. While the size of ethnic minority populations may be smaller than in the United States, the speed of growth in these minorities is likely to be much more rapid in Western Europe. This unprecedented increase in migrant populations could exacerbate ethnic social tensions, particularly in urban areas.
The broad nature of these essays suggests that advanced population aging will emerge within the context of many types of policy debates in the coming decades. While these 11 brief essays only scratch the surface of their respective areas of research, they provide a broad introduction to the politics of advanced population aging.

A World Without AIDS, Still Worlds Away
›August 6, 2012 // By Wilson Center StaffThe original version of this article, by Lawrence K. Altman, appeared on The New York Times.
Is the world on the verge of ending the AIDS epidemic and creating an AIDS-free generation, even though a cure and a vaccine are still distant hopes?Yes, roared enthusiasts among the nearly 24,000 participants at the 19th International AIDS Conference here last week. Their hopes are based on the extraordinary scientific gains made since the conference was last held in the United States, 22 years ago, when an AIDS diagnosis was a sure death sentence.
Among those gains: antiretroviral drug combinations for women to prevent infection of their newborns; drugs to treat and prevent infection with HIV, the virus that causes AIDS, among adults; and evidence that voluntary male circumcision can reduce the risk of female-to-male transmission by 50 to 60 percent.
Today, HIV has become a chronic disease that, if treated appropriately, can be held at bay in a newly infected young adult for decades — if the patient adheres to the rigid daily drug regimen.

Emmanuel Karagiannis: Mediterranean Oil and Gas Discoveries Could Change Regional Alignments, Global Energy Equation
›“The discovery of gas reserves in the eastern Mediterranean comes at a time when world demand for energy is growing rapidly and many are questioning the reliability of supplies from North Africa and the Middle East,” said Emmanuel Karagiannis, assistant professor of Russian and post-Soviet politics at the University of Macedonia, in an interview at the Wilson Center.
The newly-discovered fields contain about 122 trillion cubic feet of recoverable natural gas reserves, 25 trillion of which are located within Israeli territorial waters. “That’s twice the reserves Libya has,” according to Karagiannis. The remaining fields have been claimed by the Republic of Cyprus, the Turkish Republic of Northern Cyprus, Syria, and Lebanon.
Europe currently depends on Russia for most of its gas supplies, so the new fields could provide an “important alternative source for European economies,” said Karagiannis.
The discovery also has the potential to increase stability in the region by serving as an incentive for nations to work together. “For example, Israel and Cyprus have come closer to each other in many respects, including military cooperation,” Karagiannis said. Greece and Israel have also strengthened their relationship, in part due to the historical relationship between Cyprus and Greece but also because the latter could serve as an energy hub to transport gas throughout Europe, he said. “In effect Israel, Greece, and Cyprus could form a new axis of stability in the region.”
“Turkey can also play a significant part in the business of transporting energy resources to Europe,” Karagiannis said, but Syria and Lebanon, the two other countries that lie adjacent to the newly discovered gas reserves, are less likely to benefit in the near future from the find, given their current political circumstances. “It’s very difficult to imagine their participation in the regional energy projects,” he said. Lebanon has tried and failed to sell offshore exploratory licenses twice due to its lack of a state petroleum administration, while the current uprising against President Bashar al-Assad is preventing any progress in Syria.
In part as a result of these political challenges, the gas fields also have the potential to generate conflict in the region. There will be a divide between “haves and have-nots,” explained Karagiannis. According to a report by the Institute for National Strategic Studies, “piping Israeli gas to the RoC [Republic of Cyprus] and then onto Turkey, which could be the gateway to the European market, is unlikely due to current tensions between Ankara, the RoC, and Tel Aviv.” Since the discovery of the fields, “Turkey has already issued military threats against Cyprus in order to stop the gas exploration process that is currently taking place in the Cypriot Exclusive Economic Zone,” Karagiannis said. The Israeli government issued a response to the threat, stating that they are committed to protecting energy infrastructure in the region.
The first new natural gas field in the region is expected to begin full-scale production this year, with two additional fields coming on-line over the next six years.
