A mapping of populism.

Summary It is now a fact that the vote for populist parties or candidates takes place primarily on the margins or outside large urban areas. This chapter intends to show that, although powerful economic processes lead to an increased polarization between cities and peripheral areas in developed countries, this does not automatically lead to voting for populist parties. It is indeed through social networks and forms of sociability that the experience of relegation gradually comes to feed a strong resentment against cities and their inhabitants. In other words, the factors at work in the success of populist parties are deeply rooted in territorialized social structures, which cannot be reduced to simple dimensions of class or ethnicity.
