Abstract
Using hierarchical cluster analysis, a new measure of democracy, the DCC index, is proposed and constructed from five popular indices of democracy (Freedom House, Polity IV, Vanhanen's index of democratization, Cheibub et al.'s index of democracy and dictatorship, and the Cingranelli-Richards index of electoral self-determination). The DCC was used to classify the regime types for twenty-four countries in the Americas and thirty-nine countries in Europe over a thirty-year period. The results indicated that democracy is a latent class variable. Sensitivity and specificity analyses were conducted for the five existing democracy indices as well as the newly proposed Unified Democracy Scores index and a predicted DCC score. This analysis revealed significant problems with the existing measures. Overall, the predicted DCC index attained the highest level of accuracy although one other index achieved high levels of accuracy in identifying non democracies.
