The author of this article describes residential segregation of foreigners in Barcelona. She presents some theoretical considerations, makes statistical calculations pertaining to the problem, and defines causal factors of residential segregation. What is important, residential segregation in Barcelona may be far deeper than in other cities because of the relatively strong separatism in Catalonia and the required knowledge of the Catalan language. These factors make full access to local labour market very difficult for immigrants and lead to their marginalization. In the statistical calculations a measure of residential segregation (Duncan, Duncan 1955) is used which allows a comparison of the situation in Barcelona and in other cities, as well as an analysis of changes in Barcelona in recent years.
Multiculturalism is a kind of social policy that depends on cultural neutrality of the state. Huge communities of immigrants of non-European cultures arose in Western Europe. In response to this phenomenon, European states initiated a multicultural social policy. In effect, many behaviours of immigrants turned out to be at variance with human rights, but consistent with multiculturalism. Great cultural distance between European societies and immigrants caused more serious problems with integration than had been expected. Nowadays, we can observe a contestation, but not abandonment, of the multicultural policy, accompanied by anti-immigrant sentiments. A new social policy ought to facilitate the adaptation of immigrants in economic and politic institutions, and to respect human rights as a key value.
