The central theses of William Strauss and Neil Howe's book Generations
are reviewed and data they present on national leadership shares of s
uccessive cohort generations are analyzed. Their generational cycles a
re shown to repeat with Kuznets cycle/Kondratiev wave rhythmicity, and
generational shifts to coincide with long-wave crises. This discovery
leads to a reevaluation of their generational typology from the Civil
War to the Great Depression and a reformulation of the generational c
haracterizations in a format consistent with long-wave relationships o
f polity and economy. The effect is to enrich and generalize both gene
rational and long-wave theory.
