Interviewer instructions
Item 18: Survey code: Whether the originally selected sample household or a substitute household has been surveyed will be indicated against this item by recording code "1" if the originally selected household has been surveyed and code "2" if the substitute household has been surveyed. If neither the originally selected household nor a substitute household could be surveyed, i.e., if the sample household is a casualty, code "3" will be recorded. In case of a casualty only the blocks 0, 1, 2, 10 and 11 are to be filled up and on the top of the front page of the schedule the word "CASUALTY" will be written in block capitals.
