    Sammanfattning : Structural changes in society have often been related to social problems such as crime, alcoholism and social elimination. In this analysis of the development of social elimination in Sweden during the period 1860-1975, which is mainly based on official data, it is demonstrated that there is not always a causal relationship between structural change and such social problems.
