P13: What is [the respondent's] predominant language of communication?

You are required to find out the predominant language the person uses most frequently for his/her day-to-day communication with his/her neighbours, at factory, in office, in market places, etc. Note that it is not necessary that a person may be able to read and/or write in this language. For babies who have not yet started talking, or for the deaf and dumb, write code 88 for Not Applicable and shade appropriately.
