This essay studies the migration crisis’ effect on the sympathy of the Sweden Democrats party. With a focus on the time period between 2010 to 2023, it aims to show if the 2015 migration crisis had any effect on the sympathy amount of the Sweden Democrats, while also analyzing the difference in effect depending on gender, age and education level. The study also aims to show if there has been a post-migration crisis effect in the years after the crisis. The method was a statistical analysis, using statistics from Statistics Sweden from the years between 2010 and 2023. Previous research has shown that a large amount of migration has an effect on voting behavior, creating a shift towards the right. However, this study suggests that the migration crisis cannot be used as an explanation for the increased sympathies of the Sweden Democrats, although the results show that there has been a post-migration crisis effect. The results also disclose that age, gender and a post-secondary education have a significant effect on sympathies for the party. Young people are less likely to sympathize with the Sweden Democrats, while men are much more likely to sympathize with the party compared to women. Individuals who hold a post-secondary education are less likely to sympathize with the party compared to those who hold a pre-secondary education.
