This study investigated the Ghettoization and Causes of the Immigrant Settlement in Sweden. As a result of the analysis, it was possible to partially explore the phenomenon of hyperghetto, city relegation, precariatization, and ghettoization of migrants. The period of industrialization Sweden Malmö is one of the richest cities and has a reputation as a social, economic, cultural and international city in Sweden, but recently it has become a city of poverty, unemployment, polarization of housing, City demolition is occurring. Although Swedish immigrants can not assume that precariat is going on, they are unstable and somewhat latent when they compare employment, unemployment, poverty and inequality to the Swedish. Of the Malmö region in Sweden, Rosengård is a place where more than 90% of the migrants live and can not integrate with the Swedish culture, but will continue to form and maintain the Arab-Islamic culture. In addition, they are socioeconomically vulnerable, and they are more likely to reproduce the present state rather than social movements and have become increasingly isolated. The policy characteristics of the countries influencing hyperghettoization were due to the failure of urban planning, the nature of pro - marketism, and the policy of refugees. Miljonprogram(Million Program: MP), a large-scale housing construction project for social integration in the 1960s and 1970s, was misguided and unlike the original intention, the residential area was not linked to other social activities such as culture and economic activities. This has not led to the purchase of housing by the middle class or the labor class, and the immigrants centering on the socially vulnerable classes have been concentrated. In addition, the privatization policy, which started with the right of the right - wing regime in the 1990s, led to the polarization of housing, and the permission of private schools created the phenomenon of separating into racial and class divisions. And the Swedish refugee policy also influenced ghettoization, a failure of the government's overloading and refugee dispersion policies due to generous refugee policies. With the refugee-friendly policies of the Swedish government, many refugees have come to the country and the government has been unable to cope with welfare, housing, medical and social expenditures. In addition, the refugees were distributed evenly in Sweden, but they did not succeed due to the absence of job or social network.
