Sundanese language
A very diverse province, Banten is populated by many ethnic groups, the most dominant being the Bantenese people. Therefore, the Sundanese language forms the lingua franca of the province, although Indonesian is the main official language. The Javanese language is also spoken by many Javanese migrants from Central or East Java. In the Lebak Regency lives the semi-isolated Baduy people, who spoke the Baduy language, an archaic form of the Sundanese language. Nonetheless, most of the people in Banten can speak Indonesian as fluently as their second language.
