Interviewer instructions
The description of the principal household industry-occupation will be recorded in the space provided. The right hand side of item 2 has been divided into two lines. The appropriate three digited industry code of the NIC 1970 will be recorded in the first line and the relevant occupation family of the NCO 1968 will be entered in the second line.
To determine the principal household industry-occupation, the general procedure to be followed is to list all the gainful
occupations pursued by the members of the household excluding those employed by the household and paying guests (who in view of their staying and taking food in the household are considered as its normal members) during the one year period preceding the date of survey, no matter whether such occupations are pursued by the members in their principal or subsidiary (on the basis of earnings) capacity. Out of the occupations listed, that one which fetched the maximum earnings to the household during the last 365 days preceding the date of survey would be considered as the principal household occupation. It is quite possible that the household occupation, thus determined as the principal one, may
be pursued in different industries by one or more members of the household. In such cases, the particular industry out of all the different industries corresponding to the principal occupation, which fetched the maximum earnings, should be considered as the principal industry of the household . In extreme cases, the earnings may be equal in two different occupations or industry- occupation combinations. By convention, in such cases, priority will be given to the occupation or industry-occupation combination of the senior most among the participating members. For households deriving income from non-gainful activities only, a dash (-) may be put against this item.
