An important issue for sociologists, and indeed for all of society, is why these changes in marital patterns have occurred. In this essay I will seek to critically examine a number of sociological explanations for the 'divorce phenomenon ' and also consider the social policy implications that each explanation carries with it. It will be argued that the best explanations are to be found within a broad socio-economic framework.
