Turnout determinants in democracies and in non-democracies

Elections are celebrated in democracies as well as in non-democracies. Studies on the factors explaining turnout normally focus, however, only on democracies. Are turnout patterns different in non-democracies? If so, how different are those? In this paper I address this issue with a unique dataset covering 1251 elections −678 democratic (in 107 countries) and 250 nondemocratic elections (in 81 countries) for the lower house and 209 democratic (in 57 countries) and 114 nondemocratic (in 60 countries)- for the period 1961-2008. I find that the turnout determinants are contingent upon the regimes and that the most important differences lay in the institutional and in the political factors.
