In troubled waters, conservatives gain: An analysis of depopulation and electoral behaviour in the heart of empty Spain

Abstract

Over the last years, political parties have increased their efforts to garner electoral support in the so-called ‘empty Spain’. A part of Spain, where recent depopulation dynamics have been intense, allocates 79 parliamentary seats in the Spanish Congress of Deputies and it has emerged as an important electoral asset. Yet, what is the relationship between depopulation and political behaviour? Has the decrease in population benefited or damaged certain parties? As a result of it, has electoral participation increased or decreased? Using a new dataset that includes the share of the votes of different parties and the depopulation dynamics between 2008 and 2019, this article aims at contributing to the existing literature by analysing a phenomenon which we still know little about. To do so, we use the five regions that, according to Sergio del Molino (2016), make up Empty Spain. The analyses indicate that depopulation is related to a significant increase of mobilization and vote for the conserva-tive parties, an effect that is fundamentally driven by demographic compositional changes triggered by young people, who are more likely to be left-wing, but also more likely to move out to urban areas.
