Before World War II, minorities represented more than 28% of the total population. During the war that percentage was halved, largely by the loss of the border areas of Bessarabia and northern Bukovina (to the former Soviet Union, now Moldova and Ukraine) and southern Dobrudja (to Bulgaria). Two-thirds of the ethnic German population either left or were deported after World War II, a period that was followed by decades of relatively regular (by communist standards) migration. During the interwar period in Romania, the total number of ethnic Germans amounted to as much as 786,000 (according to some sources and estimates dating to 1939), a figure which had subsequently fallen to circa 36,000 as of 2011 in contemporary Romania. One of the reasons for which the number of Germans in Romania fell is because after the Romanian Revolution there has been a mass migration of Transylvania Saxons to Germany, in what was referred by British daily newspaper Guardian to as 'the most astonishing, and little reported, ethnic migration in modern Europe'. Of a total population of three quarter million Jews before World War II, about a third were killed during the Holocaust. Mass emigration, mostly to Israel and United States, has reduced the surviving Jewish community to less than 6,000 in 2002 (it is estimated that the real numbers could be 3-4 times higher). 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. Minority populations are greatest in Transylvania and the Banat, areas in the north and west of the country, which were part of the Kingdom of Hungary (after 1867 the Austria-Hungary) until the end of World War I.
