Abstract

Structural-demographictheory is a conceptual tool for understanding and explaining long-term social pressures that can lead to revolutions, civil wars, and other major outbreaks of socio-political instability. This articledevelopsa general modeling framework for quantifyingsuchstructuralpressures towardinstability. Following the basic premises of the structural-demographic theory, the approach adopted here decomposes pressures toward instability into three components, dealing with the general population, elites, and the state, respectively. Several feedback loops affecting the dynamics of these components are modeled explicitly, including the effect of labor oversupply on real wages and on elite overproduction. I apply the modeling framework to two empirical case studies :investigating structural-demographic dynamics during the nineteenth century (with a focus on the period preceding the American Civil War) and during the twentieth century (with a focus on the contemporary period).

The real wage of a US worker today is less than it was 40 years ago—but there are four times as many multimillionaires. As inequality grows, the politics become more poisonous. Every year, more and more Americans go on shooting sprees, killing strangers and passers-by—and now, increasingly, representatives of the state. Troubling trends of this kind are…

What Complexity Science Tells Us about the Evolution of Complex Societies

Why do the 99.9% of humanity live in large-scale societies organized as states? During the Holocene (the last 10,000 years), human societies have been transformed utterly: from small groups of nomadic foragers to our current interconnected world of large-scale societies organized as states. Population numbers, agricultural productivity, technological…
