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.
South Slavic languages
This dialect is spoken primarily in the federal state of Burgenland in Austria and nearby areas in Vienna, Slovakia, and Hungary by descendants of Croats who migrated there during the 16th century. This dialect (or family of dialects) differs from standard Croatian, since it has been heavily influenced by German and Hungarian. It has properties of all three major dialectal groups in Croatia, since the migrants did not all come from the same area. The linguistic standard is based on a Chakavian dialect, and (like all Chakavian dialects) is characterized by very conservative grammatical structures: for example, it preserves case endings lost in the Shtokavian base of standard Croatian. At most 100,000 people speak Burgenland Croatian and almost all are bilingual in German. Its future is uncertain, but there is movement to preserve it. It has official status in six districts of Burgenland, and is used in some schools in Burgenland and neighboring western parts of Hungary.
