Age-structural Political Demography

 

In the United States, economic demography and age-structural political demography have similar intellectual roots. The earliest theoretical exposition of the effects of population age structure on the state was published in 1958 by Ansley Coale and Edger M. Hoover. [1]  Coale and Hoover focused on the relative decline in the ratio of childhood dependents to potential workers, and thus the opportunity for accumulating savings and for greater per-child investments in education, both by the household and the state—effects that were later quantified by research (in more than 40 countries) on life-cycle income, consumption and transfers conducted by Ronald Lee and Andrew Mason.[2]  Because declining fertility ultimately slows workforce growth, Coale and Hoover also foresaw opportunities for reduced competition among young adults vying for jobs—an effect first observed empirically by Richard Easterlin in the late 1980s.[3]

Job competition and under-employment among young adults in countries with youthful populations served as the basis for Herbert Möller’s theory, published in the late 1960s, explaining the vulnerability of states with youthful age structures to militarism and armed conflict in the 19th century.[4] This theory was pursued again, in more detail, by Jack Goldstone in his research on the emergence of large youthful cohorts in early modern Europe and Asia, and their link to revolution.[5] Goldstone’s research was later complimented by Christian Mesquida’s research on the relationship between the ratio of young-adult men to older adult men, and its association with the intensity of late-20th century conflict.[6] In 2006, Henrik Urdal published his research on age-structure’s statistical effect on the onset of conflict.[7]
