As the UN High-Level Forum on Sustainable Development continues this week, member states and civil society are taking a hard look at countries’ progress toward securing safe drinking water, sanitation, and adequate housing. Achieving these and the other Sustainable Development Goals (SDGs) requires recognizing the synergies among them—including the role that reproductive health and family planning can play. You may ask, “Why does family planning matter for the SDGs not related to health?” The answer is that it is one of the most cost-effective investments for achieving the SDGs. Increasing access to family planning provides sweeping social, economic, and environmental benefits for every dollar spent.

From mass urbanization to massive refugee flows, high fertility to record low birth rates, global population is changing in unprecedented ways.  “Everybody Counts,” a new podcast series hosted by Rhodes College Professor and Wilson Center Global Fellow Jennifer D. Sciubba, launches a lively and thoughtful conversation about the ways human population shapes our world and how we live today.

Although most of us picture refugees living in remote, dusty camps, as many as 2.1 million of the developing world’s working-age refugees reside in major urban areas—where they should have greater access to employment opportunities. However, according to a new report from the Center for Global Development, finding employment remains “one of the major unmet needs identified by refugees.”

“Community mobilization, local capacity-building, and innovation are the cornerstones of successful development. And that for us includes resilience,” said Franklin Moore, Africare’s Chief of Programs, at a Wilson Center event on family planning and sustainable development. As rapid population growth intersects with challenges like food insecurity and water scarcity, communities in developing countries need not only the capacity to absorb short-term shocks, they also need transformative capacity to address long-term challenges.

“When you enable a family to be able to time and space their children, you actually improve the overall health of that family,” said Dr. Alma Golden, the Deputy Assistant Administrator of USAID’s Bureau for Global Health, at a recent Wilson Center event on the role of faith-based organizations in family planning. Faith-based groups are an “irreplaceable asset,” said Dr. Golden, when it comes to fighting stigma and marginalization and promoting positive health behaviors.

Iraqi Kurdistan is blessed with abundant water resources, but these resources are under increasing stress. Changing demographics, dam building in neighboring countries, and drought have driven Kurdish hydropolitics to a critical juncture where two distinct water futures are possible—and both have implications for regional stability and for U.S. interests.

Today, African leaders agree that Africa has a great opportunity to reap economic benefits from strategic investments made in the continent’s current large youthful population. The “demographic dividend” is the accelerated economic growth that can result from improved reproductive health, a rapid decline in fertility, and the subsequent shift in population age structure. With more people in the labor force and fewer children to support, a country has a window of opportunity—but only if the right social and economic investments and policies are made in health, education, governance, and the economy.
