It should be an excellent time to be a young Iranian: High school and college enrollments in the Islamic Republic rank near the top of Muslim-majority countries. Women have only about two children on average, compared to 6.5 in the mid-1980s. And childhood mortality is projected to approach North American levels in the next 15 years. Yet, as the recent protests show, many young Iranians feel left out. Job growth—especially for young adults—has failed to keep pace with development, while persistently high rates of inflation steadily drive up the cost of living and cut deeply into Iranians’ savings.

“There is no healthcare delivery system for non-pregnant 15- to 24-year olds,” said the U.S. Global AIDS Coordinator, Ambassador Deborah Birx, at a recent Wilson Center event on efforts to reduce the prevalence of HIV/AIDS among adolescent girls in sub-Saharan Africa. In 2014, the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) established the DREAMS program, which aims to create “a health care system where young people interact in a proactive and positive way,” said Birx.

Over the past 25 years, economic and political demographers have documented how declines in fertility rates have preceded improvements in state capacity, income, and political stability in much of East Asia, Latin America, and, most recently, in the Maghreb region of North Africa (Tunisia, Morocco, Algeria). Nonetheless, social scientists still debate over where and when this “demographic dividend” will occur in the youthful, low-income countries of sub-Saharan Africa.  Elizabeth Leahy Madsen of the Population Reference Bureau and I find that, for most youthful countries—like those in sub-Saharan Africa—changes in population age structure provide a means to gauge the timing of their future development.

“Resilience means the ability to cope and move ahead,” said Joan Dalton, the gender lead at THINK Liberia during the second session in a series of conversations on resilience and health at the Wilson Center. As conflicts, epidemics, and natural disasters increasingly leave global health systems vulnerable to devastation, it is important to build resilient health systems through interventions that support community resilience, agreed global health experts at the panel event co-hosted by CARE and the Maternal Health Initiative.

While attention in the United States is focused on the disasters in Puerto Rico and the Caribbean, a crisis across the Atlantic is rapidly becoming one of the worst humanitarian disasters since World War II. In the Lake Chad basin of West Africa, about 17 million people are affected by the emergency, struggling with food insecurity, widespread violence, involuntary displacement, and the consequences of environmental degradation. An estimated 800,000 children suffer from acute malnutrition; and although international donors pledged $672 million in February, the famine and humanitarian misery continues unabated. Suicide bombings and attacks by Boko Haram, which have killed at least 381 civilians since April 2017, have forced many people to leave their homes and farmers to leave their lands, interrupting livelihoods and reducing food supplies.

Girls and women bear the brunt of climate change impacts. Natural disasters kill more women than men: an estimated 90 percent of those killed in some weather-related disasters were female. The effects of climate change on natural resources can also further exacerbate existing gender inequalities.  Girls may be kept out of school to fetch water, as droughts drive them to walk farther and farther to find it. Seeking to stretch scarce household resources, families may marry off their daughters before the legal age and they may become more vulnerable to human trafficking after natural disasters.

The future of global security will depend in large part on the fate of today’s 1.2 billion young people. Do youth between the ages of 15 and 24—a critical phase of life—possess  the necessary social, physical, intellectual, and financial building blocks to underpin productive, healthy adulthoods? Or do they lack this solid base, putting them at risk of personal and social instability?
