Hungarians (Magyars; "see Hungarians in Romania", especially in Harghita, Covasna, and Mureș counties) and Romani (Roma; "see Romani people in Romania") are the principal minorities, with a declining German population (Banat Swabians in Timiș; Transylvanian Saxons in Sibiu, Brașov and elsewhere), and smaller numbers of Czechs, Slovaks, Serbs, Croats, and Banat Bulgarians (in Banat), Ukrainians (especially in Maramureș and Bukovina), Greeks of Romania (especially in Brăila and Constanța), Turks and Tatars (mainly in Constanța), Armenians, Russians (Lipovans, Old Believers in Tulcea), Jews and others. Since the Romanian Revolution of 1989, Bucharest and other cities have again become increasingly cosmopolitan, including identifiable presences from outside the EU (Chinese, Turks, Moldovans, Syrians, Iraqis, Africans) as well as from the EU (French, Italians, Germans, British, Greeks). In Romania, there are also guest workers from countries such as Vietnam and Nepal.
