CHANGE IN VOTING TURNOUT, 1952-1972

The relationship of age to voting turnout over a 20-year periodis analyzed in a multivariate model with controls for causalcovariates and "period" and "cohort" effects. The observed curvilinearpattern of turnout with age remains after holding rival factorsconstant, but the apparent curvilinearity of cohort membershipdisappears. Instead, a pattern of decreasing turnout among successivelyyounger birth cohorts is found, suggesting differences in thepolitical socialization of voting obligations between the nineteenthand twentieth centuries.
