How does protest vote emerge in left-behind communities? We exploit individual data from a large survey of British households to study the significant increase in the support for the UK Independence Party (UKIP) in Great Britain in the aftermath of the financial crisis. We find that voters are more likely to support UKIP when they identify with their community and, at the same time, a larger number of people in their community experience resentment induced by a worsening of their relative income position. These findings shed new light on the key elements of resentment in communities that are left-behind by the pace of economic development.
