Islam and democracy

Using the POLITY IV and Freedom House indices, Rowley and Smith (Public Choice 139(3-4):273, 2009) found that countries with Muslim majorities enjoy less freedom and are less democratic than countries in which Muslims are a minority. Because the POLITY IV and Freedom House indices have been criticized on several grounds, I reinvestigate Rowley and Smith's finding using the new Democracy-Dictatorship data from Cheibub et al. (Public Choice 143(1-2):67, 2010). The empirical results confirm that countries with Muslim majorities are indeed less likely to be democratic.
