Mr. Cormac Halpin:

We did put extensive efforts into capturing those types of situations. We used a lot of mapping software and so on to try to identify outdwellings and dwellings that were separate to the main building, and that information would have been provided to numerators. There is obviously a legal obligation on all people who are present in the country on census night to comply, and a very big publicity operation accompanies the census. That example the Chair gave about the granny flat is probably a more likely situation whereby separate households are going to be captured because there might be more separate living arrangements in that situation if people are living in a separate building. The scenario I had in my head is one we see sometimes where a couple might, unfortunately, have separated and say they are living in the same dwelling, but they are living separate lives, if you like, and they can be separate households. That can be a little bit more blurred, but where there are completely separate dwellings then, given the intelligence we provide to our field staff in advance, we might expect to pick up those kind of situations to make sure everybody is covered.
