This report discusses variations in background of Greek-Australian high school students in Sydney, Australia, and examines and describes the pattern of individual responses to the social context. Literature on the ethnic background of Greeks in Australia is briefly reviewed, and previous findings are presented to articulate some of the issues important in this study: how is a Greek identity maintained from generation to generation after migration, what changes occur, and what are the identity conflicts, if any, of Greek students who are raised in Australia? Next, the study's framework and a rationale for the study of ethnic background factors on second generation adolescents are outlined. The methodology of the survey, which involved administering questionnaires to 1,029 Greek-Australian students, is detailed. Survey responses are given, under the headings of Ethnic Background, Internalization, Values, and Problems, and patterns in background and identity are observed. Much of this information is conveyed by statistical tables. Many variants are reported, but it is concluded that attachment of ethnic culture is quite strong and that the family group is important to the second generation. Finally, a general model is proposed for the study of the responses of second generation ethnic groups. Appendices contain the survey questionnaire and an explanation of the statistical methods used to interpret data in this study. (KH)
