Croatia
A 2011 survey revealed that 78% of Croatians claim knowledge of at least one foreign language. According to a survey ordered by the European Commission in 2005, 49% of Croatians speak English as the second language, 34% speak German, 14% speak Italian, and 10% speak French. Russian is spoken by 4% each, and 2% of Croatians speak Spanish. However, there are large municipalities that have minority languages that include substantial populations that speak these languages. An odd-majority of Slovenes (59%) have a certain level of knowledge of Croatian. The country is a part of various language-based international associations most notably the European Union Language Association.
Slovenia
A significant number of people in Slovenia speak a variant of Serbo-Croatian (Serbian, Croatian, Bosnian, or Montenegrin) as their native language. These are mostly immigrants who moved to Slovenia from other former Yugoslav republics from the 1960s to the late 1980s, and their descendants. In 2002, 0.4% of the Slovenian population declared themselves to be native speakers of Albanian and 0.2% native speakers of Macedonian. Czech, the fourth-largest minority language in Slovenia prior to World War II (after German, Hungarian, and Serbo-Croatian), is now the native language of a few hundred residents of Slovenia.
