The Great Global Divider? A Comparison of Urban-Rural Partisan Polarization in Western Democracies

This study is the first to measure urban-rural electoral divides in a way that facilitates comparisons beyond majoritarian democracies of the UK and North America. Based on national election results at the lowest available geographic level in fifteen countries covering roughly five decades, we present a measure for each election and political party, enabling comparisons over time and between countries with different electoral and party systems. We show that long-term increases in urban-rural divides have been most pronounced in the US, the UK, and Canada, but these divides have also emerged in several European multiparty systems in recent decades, largely because of growing smaller parties with predominantly urban or rural support. Overall urban-rural electoral divides remain lower in these systems due to continued presence of mainstream parties with geographically diverse support. Our contribution paves the way for a comparative research agenda on causes and consequences of urban-rural electoral polarization.
