Luxembourg has the highest percentage of residents of foreign origin in Europe. This fact evokes a multiplicity of questions related to their position in the host society and their perception by all type of residents. Despite the fact that there has not been much research published on perception of immigrants in Luxembourg, the international literature analyzing the immigrant-related sentiment in Europe shows that Luxembourg residents as a whole have generally a positive attitude toward resident immigrants: ?in 2000, negative attitudes toward foreigners were most pronounced in Greece, Belgium, Germany, and France, and least pronounced in Spain, Luxembourg, and Italy? (Semyonov et al., 2006:436). The present paper builds up on the already existing research and presents a more detailed analysis of the perception of immigrants. Specifically, it examines how the age of an individual affects its attitudes toward immigrants and how the effect of age varies among respondents with different migrant history. As we are only analyzing these relationships we don’t control by other important individual factors which also affect attitudes toward immigrants such as gender, education, professional status, etc.
