The article explores the immigration and integration strategies of Denmark and Sweden while assessing their efficacy. The two countries, sharing historical, cultural, social and economic similarities, face a common challenge: the formation of ethnoreligious enclaves primarily inhabited by individuals with a Muslim background. Due to the recent European migrant crises, there has been a notable increase in the number of migrants, leading to stricter integration policies in the Scandinavian countries. Yet, governmental approaches to address the segregation of immigrant areas vary between Denmark and Sweden. Denmark has adopted a stringent immigration policy promoting cultural assimilation of immigrants from non-Western countries, whilst Sweden follows a liberal approach advocating cultural and ethnic diversity within society. The evolution of immigration and integration initiatives in Denmark and Sweden has been reconstructed through the analysis of official documents and critical examination of political discourses. It is noted that Swedish authorities are increasingly incorporating Denmark’s more radical approaches to address migration issues within their political programmes. Despite the results of Denmark’s anti-immigration policies and the reduction in the number of segregated immigrant areas, a myriad of issues persist due to EU immigration policies. The problem of forging a new civic identity rooted in the linguistic, religious and cultural homogeneity of Danish society amidst its multiculturalism remains relevant. Thus, Sweden is formulating its own anti-segregation programme, taking into account both the successes and shortcomings of Danish immigration and integration policies. Another important conclusion is that these nations have started to pay special attention to ethnic and religious criteria when identifying ‘parallel societies’.
