Are younger countries at higher risk of civil conflict? The International Crisis Group’s 2018 list of 10 conflicts to watch suggests they might be: Like last year, intra-state conflicts (civil and ethnic conflicts within states, rather than wars between states) dominate the list, and among those, about 70 percent are within youthful countries, or states with a median age of 25.5 years or younger. The only multi-state cluster mentioned in both 2017 and 2018 lists is the Sahel, the world’s most youthful region.

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.

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.

According to political demographers, who study the relationship between population dynamics and politics, two characteristics when observed together provide a rather good indication that a state is about to shed its authoritarian regime, rise to a high level of democracy, and stay there. Myanmar has both.

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.

Among the few bright spots in the 2015 Freedom in the World Report, the brightest may be Tunisia, which for the first time was assessed as “free” – Freedom House’s highest “freedom status” and for many political scientists the definitive indication of a liberal democracy. Tunisia is the only North African state to have been assessed as free since Freedom House began its worldwide assessment of political rights and civil liberties in 1972, and only the second Arab-majority state since Lebanon was rated free from 1974 to 1976.

A quick scan through the charts and graphs of Pakistan’s most recent Demographic and Health Survey yields more than a few insights into the performance of the government’s health policies and the public health and demographic challenges it will face in the future.
