Populism and Social Polarization in European Democracies

The objective of this article is to explain populist attitudes that are prevailing in a number of European democracies. Populist attitudes usually lead to social protests and populist votes. We capture the populist wave by relying on values that are traditionally viewed as populist-such as distrust of institutions and neighbors, rejection of migrations, and strong preferences for law and order-rather than on voting behavior. Our study covers the period 2004-2018 and 25 European countries for which we match aggregated indicators of populist values and social polarization based on ESS and SILC survey micro-data. We show that social polarization varies dramatically across European regions, but at the same time, some convergence is observed. Our estimations confirm, in most cases, a positive and statistically significant relation between social polarization and populist attitudes.
