Structural-demographic theory

In social science, the structural-demographic theory (SDT, also known as Demographic Structural Theory) uses mathematical modeling to explain and predict outbreaks of political instability in complex societies. It originated in the work of sociologist Jack Goldstone and has recently been developed further by the quantitative historians Peter Turchin, Andrey Korotayev, Leonid Grinin and Sergey Nefedov.
