With UN demographers more certain than ever that global population will reach between 10 and 12 billion by the end of the century, the challenge of building a sustainable future seems daunting. But according to Wolfgang Lutz, founding director of the Vienna-based Wittgenstein Center for Demography and Global Human Capital, these projections miss one crucial variable: increasing levels of education.

“Sub-Saharan Africa’s young people are in effect the global labor force of the future,” said Jack Goldstone at the Wilson Center on October 15. “Whether they are productive, how large that cohort turns out to be, whether they find work or not, is going to have a bearing, I think, on all of us.” [Video Below]

Global crises like the Ebola outbreak force us to consider what “security” really means, said Sharon Burke, senior advisor for the New America Foundation. “Is security getting our kids to school and food on the table…or are you talking about military security and defense threats that require a weapon to counter?”

By 2045, global population will be north of 9 billion with increased urbanization and migration, natural resource stress, improved medical technologies, greater use of robotic labor, and a shift towards lifelong (and increasingly online) learning, according to a recent report from the UK Ministry of Defense.

“Half of the world’s population is under 30 – any development agenda would have to address their needs, including their health needs, as part of accomplishing development goals,” said Jennifer Adams, deputy assistant administrator at USAID’s Bureau for Global Health, at the Wilson Center on September 24.

Seasoned demography geeks know to anticipate the release of the UN Population Division’s World Population Prospects in the spring of odd-numbered years. An off-cycle update published last month in Science, summarizing new results and methodological changes to the projections, therefore provoked a buzz of interest and a mini-flurry of media coverage.
