Italy's official language is Italian, as stated by the framework law no. 482/1999 and Trentino Alto-Adige's special Statute, which is adopted with a constitutional law. Around the world there are an estimated 64 million native Italian speakers and another 21 million who use it as a second language. Italian is often natively spoken in a regional variety, not to be confused with Italy's regional and minority languages; however, the establishment of a national education system led to a decrease in variation in the languages spoken across the country during the 20th century. Standardisation was further expanded in the 1950s and 1960s due to economic growth and the rise of mass media and television (the state broadcaster RAI helped set a standard Italian).
