The article deals with demographic movements and characteristics of the present settling of Slovenes in Hungary. A number of research studies on Slovenes in Hungary have been performed yet almost exclusively on Slovenes in the Porabje, i.e. the territory of their atuochthonous settling. However, at least one third of them, and even more according to some findings, live dispersed all over Hungary. The study of Slovenes in Hungary is also an interesting methodological challenge, since three official categorics are at our disposal: according to mother tongue, to national adherence, and to language command. The Slovene community in the Porabje is believed to he legally relatively well protected, while acctually it is, apart from Slovenes in Austrian Styria the most endangered Slovene conlillunity in the neigbouring countries.
