This chapter discusses reflecting the changes in conceptualising the relationship between the ethnic and the native population. Various models have been put forward conceptualising the conflicts of relationship between the ethnic/native groups. The first model was developed by Park and Stonequist in the 1920’s and 1930’s and emphasises the association of marginal personality traits with the immigrant. The second later model presented by Goldberg, Green and more specifically Dickie-Clark, points at some of the flaws inherent in the Park/Stonequist theory by concentrating on the importance of the marginal situation rather than the marginal personality. The cultural deficit model which emerged during the 1960’s similarly assumes that the culture of the host nation is superior to that of the ethnic population, with the immigrant expected to assimilate into the host nation’s way life. In conclusion, all the models of race relations have shown that culture conflict is an inevitability in a society with an immigrant population.
