Many of the municipalities in Sweden experience socioeconomic residential segregation which increase the polarization between high- and low-income groups and contributes to a higher degree of inequality between people. Previous studies on neighbourhood effects have mainly examined on a city district level and some of them show that different factors such as health, education, participation in politics and trust in society varies depending on where you live. However, there are fewer studies investigating the segregation on a municipality level which this study does for the purpose of getting an overview of the residential segregation in Sweden. By using inequality index as a measure of socioeconomic segregation this study examines how different variables of causes and social and political consequences may correlate with the segregation. To find out if there is a connection between the inequality index and the variables supposed to be causes and consequences of segregation a regression analysis and a correlation analysis is used. The results are showing that small as well as large municipalities are experiencing a residential segregation and the weight of structures on a higher degree of socioeconomic residential segregation. There is also a correlation between the segregation and several negative outcomes on social and political variables. Based on the results, a conclusion can be drawn that the segregation not only contributes to injustice among individuals but also between the municipalities since some of them seem to possess more numerous of problems than others regarding the living environment.
