The present study pursued three aims. First, it sought to determine the distribution of types of identification among adult immigrants in France; second, it investigated certain determinants that might contribute to the emergence of exclusively French or ethnic identifications; and third, it attempted to assess the outcomes of French or ethnic identification strategies for well-being. Participants of the study were 6211 adult immigrants in France, aged between 45 and 70 years (M = 55.8, SD = 7.21), 53.6% males. Findings revealed that participants' dominant identification style of belonging was either French (n = 2758, 44.4%) or home country/ethnic group affiliation (n = 1899, 30.6%), with a greater tendency towards the former. In relation to the study second question, it was found that lower levels of education and involvement with French society, higher degrees of religiosity, and shorter lengths of residence in France were positively connected with home country/ethnic group identification as against French and vice versa. Stronger feelings of being settled in France and a command of French, and lower degrees of involvement with the initial national/ethnic community, were associated with a significant decrease in the likelihood of home country/ethnic group identification as against French and vice versa. While respondents' personal experiences of discrimination in home country/ethnic group before migration to France predicted a lower likelihood of home country/ethnic group identification compared to French and vice versa, immigrants' reports of being discriminated against in France had no significant effect on identification choices. Findings revealed also that those identifying with their home country/ethnic group recorded relatively higher degrees of maladjustment than those asserting a French identification.
