ABSTRACT
Whereas it was once an ideal that immigrant groups entering a host society would disappear into it within a generation or two, reality has shown that many remain distinct and distinctive. Certain ethnic groups maintain high levels of concentration long after they have ceased to be immigrants, a result of spatial segregation or social prejudices which militate against their full integration or assimilation (Kantrowitz 1981, Jackson 1981). Some others appear to occupy an intermediate position, creating ethnic clusters but avoiding segregation, while at the same time integrating functionally into the host society.
