Migration and multiculturality are not new phenomenon to Europe but recent periods of unprecedented human movement have established new and evolving diasporic configurations. The problems of migration and settlement are many and complex with different countries presenting their own issues both for and by the minorities within them. In addition there is a growing awareness of the specific needs of refugees and asylum seekers and particular concerns continue to echo across Europe given the rise in overt racisms and xenophobia. Social work cannot be indifferent to these often turbulent circumstances and the profession needs to accept the responsibility of taking a role in the social integration of Europe. This work critically examines key concepts such as assimilation, multi-culturalism, racism, marginalisation and social exclusion. It should providea valuable resource for social work practitioners and educators working with migrant communities throughout Europe.
