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.
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.
The Ruthenians are not in a majority in any county, but in four they form a minority of from 36 to 46% (Maramaros, Bereg, Ugocsa, Ung) and in three others (Sáros, Zemplen, Szepes) a minority of from 8.2 to 19.7%.
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.
Pop. (1900) 159,618, of whom over 80% were Poles, Io% Germans, and 8% Ruthenians; nearly 30% of the population were Jews.
