The turnout rate among eligible voters in the states, 1980–2000

AbstractAggregate voter turnout rates in the United States have been used in many political science studies, as both a dependent and an independent variable. Most of these studies use the voting-age population as the denominator in their turnout rate measure. However, the voting-age population is not the same as the population of eligible voters. I demonstrate why this distinction matters and outline the steps to construct the voting-eligible population for each of the states from 1980–2000 to provide more accurate measures of state-level voter turnout rates.
