While the Swedish welfare state has undergone an intensified market orientation and a number of cutbacks since 1990, it has maintained many of its universal characteristics. It still provides all residents with a rather extensive system of benefits from the cradle to the grave. This chapter contributes to a systematic and detailed analysis of eligibility criteria and conditions for accessing social benefits in five core policy areas of the Swedish social security system. As universalism continues to be a cornerstone of the Swedish welfare state, nationality or the immigration status of a person does not condition his/her entitlement to social security benefits. More recently, however, a political debate has emerged regarding immigration and the welfare system, both in terms of the benefit system being a magnet that attracts migrants and concerning the capacity of the system to cope with large-scale immigration. By discussing the main features of the Swedish welfare regime and key patterns and policy developments in the field of migration, the chapter seeks to account for recent developments, trends and directions in the access to social protection for residents, non-national residents and non-resident nationals.
