Interviewer instructions
Ensure that all buildings are given NBS numbers serially.
Many structures have distinct addresses given by the local authorities but where these are not given, NBS identifying numbers will suffice.
The use of HU should be indicated by codes ranging from 1 (residential) to 10 or 0 (other).
All residential HUs should be listed serially. A residential unit is one that has been coded 1, or 4 or 5 in col. 3
An HU may have more than one HH. As such all households in a residential HU must be listed before listing the next HU.
