According to the language in common use, 95% of the population was German, 4.66% was Czech, and the remainder was composed of Poles, Slovaks, Ruthenians, Croatians and Italians.
Of the emigrants in 1906, 52,121 were Magyars, 32,904 Slovaks, 30,551 Germans, 20,859 Rumanians and 16 0 016 Croats.
The Sla y s, the most numerous race after the Magyars, are divided into several groups: the Slovaks, mainly massed in the mountainous districts of northern Hungary; the Ruthenians, established mainly on the slopes of the Carpathians between Poprad and Maramaros Sziget; the Serbs, settled in the south of Hungary from the bend of the Danube eastwards across the Theiss into the Banat; the Croats, overwhelmingly preponderant in Croatia-Slavonia, with outlying settlements in the counties of Zala, Vas and Sopron along the Croatian and Styrian frontier.
Of these the Slovaks are the most important,, having an overwhelming majority in seven counties (94'7% in Arva, 66.1% in Saros), a bare ma j ority in three (Szepes, Bars and Poszody) and a considerable minority in five (40.6% in Gomor, 22.9% in Abauj-Torna).
Thus the Servians are mostly Greek Orthodox; the Ruthenians are Uniat Greeks; the Rumanians are either Greek Orthodox or Greek Uniats; the Slovaks are Lutherans; the only other Lutherans are the Germans in Transylvania and in the Zsepes county.
