Interviewer instructions
Item 3: principal occupation (NCO-2004): The description of the principal household occupation will be recorded in the space provided. As in case of principal household industry, the description of the principal occupation, too, should be recorded in as specific terms as possible based on the description given by the informant. In other words, the occupation description should not be copied from the NCO booklet if the informant's description gives a clearer idea of the principal occupation pursued by the household. The appropriate three-digit occupation code of the NCO-2004 is to be recorded in the entry cell, which has been trisected for recording each digit separately. For households deriving income from non-economic activities only, a dash (-) may be put against this item. For the definition of principal household occupation see paragraph 1.8.36, Chapter One of "Instructions to Field Staff" provided as related documents.
