Data from a representative sociological survey with persons of reproductive age in the Republic of Bulgaria are analysed and discussed in the article. The focus is on the attitudes and distances of ethnic Bulgarians towards the Bulgarian nationals of Turkish origin. Fifteen key attitudes towards the Bulgarian nationals of Turkish descent are analysed in addition to an age-related interpretation of the attitudes towards the mixed marriages between ethnic Turks and ethnic Bulgarians. From a social integration perspective, the analysis and interpretation take into account important characteristics of the ethnic Bulgarians such as their education, gender, place of residence, etc. The results show that among the Bulgarian community, the negative attitudes towards mixed marriages dominate, although among the different subgroups the attitudes are nuanced and ambiguous.
