Early advances in age-structural political demography were pioneered within the (U.S.) National Intelligence Council’s Long-range Analysis Unit (now called “Strategic Futures”). That work has continued through collaborations between the NIC and political demographers. Some of the NIC’s political demography products are featured in three of hte NIC’s quadrennial strategic foresight series, entitled Global Trends.
Political demography can be found in the following sections in these 3 Global Trends publications, beginning in 2008:
Global Trends 2025, A Transformed World (published 2008): Chapter 2: the Demographics of Discord, pp. 19-26.
Global Trends 2030, Alternative Worlds (published 2012): MEGATREND 3, Demographic Patterns, pp. 20-29.
Global Trends: Paradox of Progress (published 2016): People, pp. 161-166.
