Social insurance is an important part of the Swedish social security system. Swedish social insurance covers most people who live or work in Sweden. The social insurance system is administered by the Swedish Social Insurance Agency (Försäkringskassan). The purpose of the social insurance system is to provide financial security during the various stages of life. It provides financial protection for families and children – for example, for people with disabilities, illnesses, work injuries, and for old people.
To be eligible for social insurance benefits, you must, as a general rule; either formally reside in Sweden or be employed and work here. Read more at www.Forsakningskassan.se
