The Swedish compulsory school system has shifted from one of the most publicly dominated and centralized school systems in Europe, into one of the most decentralized. This process has resulted in a system that is more focused on competition. The question about free choice and how it influences residential and social segregation is widely debated on all levels in Swedish society. The government states that no school should be socially or economically segregated and that it’s important that pupils in schools have different experiences, social backgrounds and gets in contact with different cultures. The main focus in this paper investigates the free choice in the compulsory school, and thereby the movement of children between different schools in three middle sized cities from 1992 to 2004. Are these movements leading to an increased segregation within these cities and in the Swedish compulsory school system?
