“Global Political Demography” in progress [Sept. 2018]. Editors Achim Goerres (U. Duisburg-Essen) and Pieter Vanhuyesse (U. Southern Denmark) are currently managing the review and editing processes of Global Political Demography, which is scheduled to be published in 2019. The initial meeting of authors was held in November 2017, at the Käte Hamburger Kolleg/Center for Global Cooperation Research at the University of Duisburg-Essen, Germany. My contribution to this book is entitled, “Youthful Age Structures and the Risks of Revolutionary and Separatist Conflicts” (author: Richard Cincotta).
