This chapter discusses the link between migration and welfare in Latvia. In general, the Latvian social security system may be described as a mixture of elements taken from the basic security (where eligibility is based on contributions or residency, and flat-rate benefits are provided) and corporatist (with eligibility based on labour force participation and earnings-related benefits) models. The country has experienced significant social policy and migration-related changed during the past decades. This chapter focuses on the current Latvian legislation, by closely examining the differential access to social protection benefits of resident nationals, foreigners living in Latvia and Latvian citizens residing abroad across five core policy areas: unemployment, health care, pensions, family benefits and social assistance. Our results show that the Latvian social security benefits are generally based on the principle of employment, social insurance contributions, and permanent residence. Most of the social benefits and services are available to socially insured permanent residents. At the same time, the state offers minimum protection to non-insured permanent residents. Foreigners with temporary residence permits who are not socially insured are the least socially protected group.
