India - Service Sector in India 2006-07, NSS 63rd round

Item 20: Reason for: casualty (list frame)/ substitution of original enterprise (area frame): As the description suggests, this item will serve a twin purpose. On one hand, reason for casualty for an enterprise belonging to list frame will be recorded here. On the other, if an enterprise of either segment 1 or segment 2 was originally selected but a substitute was ultimately surveyed, the reason for first substitution will be recorded in this item.

If an enterprise belonging to the list frame cannot be surveyed, it will be treated as casualty. Such an enterprise may become 'CASUALTY' due to several reasons. It may be currently under the latest ASI frame, which renders itself outside the survey coverage. The enterprise may even turn out to be a Government or PSU unit.

Alternatively, during the entire reference year, the unit may not be operating at all or was closed due to some reason or other like strike, lockout, etc. These different reasons of the list frame unit becoming a 'CASUALTY' will be captured in this item. Detailed description of the actual reason for code '9' in such enterprise will be written.
The corresponding codes are:
Government/ PSU/ under the coverage of ASI - 1,
non-operative/closed during the reference year-2, non-traceable - 3,
in operation during the reference year but data could not be collected - 4,
enterprise found to be outside survey coverage at detailed enquiry stage-5,
others(specify) - 9.
In case of area frame enterprise, reason for substitution will be written under the same item, the codes for which are:
informant: busy - 1,
not available - 2,
non-cooperative - 3,
enterprise: found to be outside survey coverage at detailed enquiry stage - 4,
others (specify) - 9.
