“The act of caregiving has unique impacts on women, in terms of economic, emotional, and physical well-being,” said Dr. Belén Garijo, the CEO for healthcare and executive board member of Merck KGaA, Darmstadt, Germany, at a recent Wilson Center event.

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.

In a world rapidly churning out unpredictable political shocks, intelligence analysts occasionally need to clear their heads of the daily barrage of newsworthy events and instead work with simple theories that discern the direction and speed of trends and help predict their outcomes. Political demography, the study of population age structures and their relationships to political trends and events, has helped some analysts predict geopolitical changes in a world that, from time to time, appears utterly chaotic.

The world of 2035 will be facing global and regional insecurities that could be “more dangerous than the second half of the Cold War era,” according to a 2016 report from the Atlantic Council.

The 2015 edition of the annual Vienna Yearbook of Population Research is a special issue on differential demographic vulnerability to climate-related disasters. Many of the 16 articles are worth reading, but here are 2 of particular interest.

The world is undergoing a period of demographic transition which presents both opportunities and challenges for governments. A report by the Atlantic Council’s Mathew Burrows, formerly of the National Intelligence Council, Reducing the Risks from Rapid Demographic Change, examines the changes in population structures across high-, upper-middle-, lower-middle-, and low-income countries.

Venezuela seems suspended at a critical juncture. Following national elections in December, the opposition Democratic Unity Roundtable was set to occupy two thirds of the 167-seat National Assembly, an upset that would reduce the late Hugo Chávez’s United Socialist Party to a distant second place for the first time and given opposition legislators the power to enact sweeping political changes.
