In the former Yugoslavia, the official designation for those who declared themselves simply as "Yugoslav" was with quotation marks, "Yugoslavs" (introduced in census 1971). The quotation marks were originally meant to distinguish Yugoslav ethnicity from Yugoslav citizenship – which was written without quotation marks. The majority of those who had once identified as ethnic "Yugoslavs" reverted to or adopted traditional ethnic and national identities. Some also decided to turn to sub-national regional identifications, especially in multi-ethnic historical regions like Istria, Vojvodina, or Bosnia (hence Bosnians). The Yugoslav designation, however, continues to be used by many, especially by the descendants of Yugoslav migrants in the United States, Canada, and Australia while the country still existed.
