Divided we abstain: Testing the effect of local income inequality on individual-level turnout using Norwegian administrative panel data

This paper investigates the relationship between income inequality and voting by utilizing exceptionally granular data that offer novel insights into local disparities. Existing research documents a larger turnout gap between rich and poor in areas characterized by high income inequality, causing concerns about further underrepresentation for low-income individuals and a larger democratic deficit. While previous studies have focused on inequality at higher aggregation levels, this paper advances the field by employing administrative data with complete income and validated voting records measuring inequality for neighborhoods hosting 1212 residents on average. The longitudinal setup allows rigorous modeling following the same individual in the same context over time. The results suggest that living in a neighborhood where the income difference between rich and poor becomes more pronounced discourages participation in national elections among low-income voters while it boosts participation among the rich, further accentuating the class-based inequality in political voice.
