the variants of Portuguese too. Moreover, all languages differ in terms of prestige: "the fact is that languages (in terms of prestige, learnability etc.) are not equal, and the law cannot make them equal". Modern developments In 2017, the "Declaration on the Common Language" (Deklaracija o zajedničkom jeziku) was signed by a group of NGOs and linguists from former Yugoslavia. It states that all standardized variants belong to a common polycentric language with equal status. Demographics About 16 million people declare their native language as either 'Bosnian', 'Croatian', 'Serbian', 'Montenegrin', or 'Serbo-Croatian'. Serbian is spoken by million people around the world, mostly in Serbia ( million), Bosnia and Herzegovina ( million), and Montenegro (). Serbian minorities are found in Kosovo, North Macedonia and in Romania. In Serbia, there are about 760,000 second-language speakers of Serbian, including Hungarians in Vojvodina and the 400,000 estimated Roma. In Kosovo, Serbian is spoken by the members of the Serbian minority which approximates between 70,000 and 100,000. Familiarity of Kosovo Albanians with Serbian varies depending on age and education, and exact numbers are not available. Croatian is spoken by million people in the world, including million in Croatia and in Bosnia and Herzegovina. A small Croatian minority that lives in Italy, known as Molise Croats, have somewhat preserved traces of Croatian. In Croatia, 170,000, mostly Italians and Hungarians, use it as a second language. Bosnian is spoken by million people worldwide, chiefly Bosniaks, including million in Bosnia and Herzegovina, in Serbia and in Montenegro. Montenegrin is spoken by people globally. The notion of Montenegrin as a separate standard from Serbian is relatively recent. In the 2011 census, around 229,251 Montenegrins, of the country's 620,000, declared Montenegrin as their native language. That figure is likely to increase, due to the country's independence and strong institutional backing of the Montenegrin language. Serbo-Croatian is also a second language of many Slovenians and Macedonians, especially those born during the time of Yugoslavia. According to the 2002 Census, Serbo-Croatian and its variants have the largest number of speakers of the minority languages in Slovenia. Outside the Balkans, there are over two million native speakers of the language(s), especially in countries which are frequent targets of immigration, such as Australia, Austria, Brazil, Canada, Chile, Germany, Hungary, Italy, Sweden, and the United States. Grammar Serbo-Croatian is a highly inflected language. Traditional grammars list seven cases for nouns and adjectives: nominative, genitive, dative,
