Immigration is a debatable topic, and Sweden offers a unique context due to its long-established liberal immigration policies and recent political shifts, making it an ideal case study for understanding broader European trends. The current study explores changes in public attitudes toward immigrants in Sweden from 2012 to 2020 using data from the final five waves (from 2012 to 2020) of the European Social Survey (ESS). Employing multi-group analysis and structural equation modeling (SEM), this research aims to identify how attitudes have shifted over the study period and to analyze significant demographic (age, gender, domicile) and socioeconomic (income, education) influences on immigration attitudes. The results reveal a shift from generally positive to more negative perceptions, particularly between 2018 and 2020. Older age groups and individuals from rural areas exhibited more negative attitudes, while females generally displayed more positive attitudes than males. Moreover, females with higher education and higher income levels also demonstrate more favorable attitudes. These findings are crucial for policymakers, as they highlight the need for strategies that address demographic influences and suggest specific areas where interventions can help reduce negative views and improve social cohesion.
