Abstract- Immigration or the percentage of foreigners is the most widely used structural variable in models explaining the vote share for radical right-wing parties in Europe. However, there is no consensus in the literature on how the percentage of immigrants or foreigners per geographical unit relates to the electoral success for anti-immigrant parties. In this article, I show that the divergent findings might stem from an ecological fallacy problem. I highlight that it is not the structural data on the percentage of immigrants, which is used by most of the literature, but perceptions of immigration that trigger increased support for the radical right.
