Language Usually Spoken
The language used by a person is not always based on his ancestry, but may be brought about by social interaction. For example, someone whose ancestors are Melayu may associate with a segment of the Javanese society and therefore, on a daily basis uses the Javanese language especially if at home they speak that language.
Language usually spoken is the language usually used in communication in the home with other members of the household. If more than one language is used, the local language and the Indonesian language, then record the local language as the answer. If more than one local language is usually spoken, record the one which is used most often.
Record the language of a person who is deaf and mute as sign language.
If a household member uses a foreign language, then record the name of the country from which the language originates.
