A survey of the status of language usage in Yugoslavia begins with an overview of the distribution of Serbo-Croatian, Croato-Serbian, Slovene, Macedonian, Albanian, and Hungarian, noting the status of all languages spoken there as nationality languages and as official languages in their speakers' republics. The equality of languages and cultures, the availability of education, the use of simultaneous translation in the parliament, and other factors contributing to a lack of linguistic unrest are outlined. A matrix follows that rates these languages on: (1) their usage rating using State Department classifications; (2) increase and decrease trends by the year 2000; (3) chief of state use in addressing the populace; (4) use in armed forces, government, court, and diplomatic communications, written and oral; (5) use as a language of instruction or required language in higher education, on the secondary and elementary levels, and in adult education; (6) use in the popular press, radio and television broadcasting, and film; (7) business and professional use, written and oral; (8) use in intellectual circles; (9) the alphabet situation; (10) the status of indigenous literature; (11) use in public signs and notices; and (12) the availability of instructional materials and dictionaries in the native languages for use in English as a second language. Explanatory notes give the number and population percentages using the languages, the type of alphabet used, and specific instructional material titles. A selected bibliography is also included. (MSE)
