This thesis has studied two things, the first thing is to see if contact between different ethnic minorities but were the ethnic majority is absent has the same alleged positive effect on generalized trust as contact between ethnic minorities and the ethnic majority. The second issue is to see if people that have contact with people with other ethnic origin than themselves changed their perception of their ethnic identity and if that effects generalized trust. This was done by using theories of social constructivism and social capital were I had an inductive theoretical approach. The research design was comparative research design, comparing heterogeneous environments were there were different ethnic minorities but were the ethnic majority was absent to ethnic heterogeneous environments were there were different ethnic minorities but were the ethnic majority was present using semis structured interviews. What I found out is that contact did in deed effect how people perceived their ethnic identity but not always in the way that the theories suggested that they should. Age seemed to have an bigger effect on generalized trust then ethnic heterogeneity. Also ethnic identity did not directly effect generalized trust but that contact and ethnic identity did in some indirect way effect generalized trust because contact led people to believe that all people are the same no matter their ethnic identity.
