In Germany the term "Sinti und Roma" is used as the endonym for "Roma". Sinti and Roma/Roma and Sinti use two Romanes terms to describe all members of the Romanes-speaking groups in the terminology of the member associations of the Central Council of German Sinti and Roma or as "Roma and Sinti" in the terminology of the Austrian self-organisations. The members of the minority, as far as they are in possession of the citizenship of their country and are regarded as "old-established" (autochthonous), are recognized as national minority in Germany under the designation "Sinti and Roma" (1997), in Austria under "Roma and Sinti" (1993).
