This is the third post in a series profiling the process of building political commitment in countries whose governments have made strong investments in family planning. Previous posts have profiled Rwanda and Iran.

While the two other countries profiled in this series, Rwanda and Iran, have only reinvigorated their family planning programs within the past 20 years, Indonesia’s story begins in the 1960s. In this respect, the world’s fourth most populous country is classified among the pioneers of family planning in the developing world and has been described as a “world leader” and “one of the developing world’s best.” An extensive community outreach program combined with a centralized government that made family planning a priority were key to Indonesia’s success story.

This is the second post in a series profiling the process of building political commitment in countries whose governments have made strong investments in family planning. Read the first post, on Rwanda’s recent rapid demographic changes, here.

To date, only 11 countries outside of the developed world, China, and a handful of small island states have reached the end of the demographic transition, with fertility rates declining from more than four children per woman to replacement level or lower.* Of these, only two countries have completed the transition in 15 years or less – and both might surprise you. One is Cuba, whose government dispensed family planning services to its relatively small population in the 1970s through accessible primary health care facilities and legalized safe abortion eight years before the United States did. The other: Iran.

Amidst world population reaching seven billion and last year’s Arab Spring, which in some nations is continuing into this winter, it can be easy to miss emerging pieces of research that tell us something relatively objective about youth and instability. Three new studies give practitioners and policymakers a stronger foundation of evidence to highlight the challenges and opportunities facing the world’s largest generation of young people.

In the nearly 20 years since the infamous intervention that resulted in the deaths of dozens of American and UN peacekeeping soldiers on the streets of Mogadishu, Somalia has become the epitome of a “failed state.” Neighboring countries, global bodies, and aid agencies are rushing to respond to the country’s rapidly evolving political, security and humanitarian crises.

While there is widespread agreement that the incidence of conflict in Africa is high, scholars and development agencies alike debate its driving forces and how to move toward solutions. Paul Williams, associate professor in the Elliott School of International Affairs at George Washington University and collaborator with the Wilson Center’s Africa Program, recently published a book that aims to both quantify African conflicts and devise a framework of their causes. In War and Conflict in Africa, Williams evaluates which factors explain the frequency of conflict in Africa during the post-Cold War era and how the international community has tried to build peace and prevent future conflict.

With over 400 people per square kilometer, the highest rate on the African mainland, population density is perhaps the most widely-discussed factor of Rwanda’s demography. Some scholars, notably Jared Diamond, have argued that it played a primary role in sparking the 1994 genocide through competition for land (although others present a more complex theory based in policies and governance).

The world’s women will determine whether the global population in 2050 is as low as 8 billion or as high as 11 billion through their choices (or lack thereof) about the number and timing of their children. Women in developing regions of the world will have the greatest effect on these potential population trajectories. Even if fertility rates remain constant at current levels (which is unlikely), developing regions would grow from 5.7 billion in 2010 to 9.7 billion in 2050, but the total population of developed countries would remain essentially unchanged.

The United Nations Population Division has estimated world population will reach seven billion on Monday. Which changes in demographic trends led us to this milestone? What do the past and present tell us about how human numbers will change in the future?

The “Day of Seven Billion” was announced this spring following the release of the latest revision of UN population projections. Although the seven billionth person will not be precisely identified, this estimate is based on careful demographic modeling. Every two years, the UN revises its projections to incorporate the latest trend data and modify its assumptions, as seemingly small changes can make a huge difference demographically.
