Contrary to earlier studies dealing with the cultural identity development of diasporic minorities, this paper assesses the impact of homogeneity on intra-group cohesion and ethnic orientation. To this end, Oromo-Americans, an ethnic group originally located within the national borders of Ethiopia, will be compared to Armenian-Americans, British-Pakistanis and Somali-Americans. Despite different circumstances, all four groups share the experience of displacement owing to war and destitution. Additionally, all groups are confronted with the ramifications of a visible minority status. In the process of comparing these groups, their degrees of homogeneity in regard to language and religion--central aspects of culture and cultural identity--will be examined and juxtaposed at a macro level. Based on the correlative relationship of group homogeneity and social cohesion, I argue that the more homogeneous a group is in terms of language and religion, the more close-knit it will be. Consequently, exiled minorities who share the same language and religion are more likely to develop and retain a strong ethnic orientation than groups who are heterogeneous with regard to language and/or religion.
