This year, 2018, marks the 60^th anniversary of a landmark publication by a pair of academic social scientists who first recognized the close relationship between population age structure (the distribution of a country’s population, by age) and development. In Population Growth and Development in Low Income Countries (Princeton U. Press, 1958), demographer Ansley Coale (1917-2002) and economist Edgar M. Hoover (1907-1992) theorized that eventual declines in fertility would transform developing-country age structures. Coale and Hoover demonstrated that these newly transformed age structures would exhibit larger shares of citizens in the working ages, and smaller shares of dependent children and seniors (Fig. 1). This transition, they argued, would someday help lift countries with youthful populations in Asia, Latin America, and Africa out of the low-income bracket.

As populations age, countries around the globe are beginning to focus attention on unpaid caregivers. Such people typically spend hours each day bathing, feeding, and helping an elderly or disabled relative. Often, they undermine their own health and career to take care of a loved one.

In Judy Brady’s iconic essay, “I Want a Wife,” the feminist activist enumerates the dozens of practical and emotional tasks wives perform as a matter of duty. At the end, she asks: “My God, who wouldn’t want a wife?”

The silver tsunami is approaching: Many countries, not all of them rich, are facing the challenges of an ageing population thanks to growing life expectancies and shrinking birth rates.

The Kurdish people’s century-long quest for self-determination reveals a key aspect of ethnic separatist conflicts. Ideas of nationhood can endure for generations, unifying people across borders and often making separatist conflicts hard to resolve. But how much harder is it to resolve separatist conflicts than other violent, non-territorial intra-state wars (such as political revolutions)? In practical terms, how much longer, on average, can policymakers expect separatist conflicts to persist and reoccur than the typical political revolution? These are tough questions. Surprisingly, demography helps us find the answers.

“There is a close relationship between fertility rates and health on one hand, and economic growth on the other,” said Peter McPherson, President of the Association of Public Land-Grant Universities and former USAID Administrator, at the final event in a three-part series on the role of population and family planning in supporting economic growth, health, and education.

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.
