Unpaid work is an absolutely critical issue, something for which we knew we need solid data. The reason the unpaid work is not in the census is that the census is not the best place to obtain it.
We have a survey called a “time use survey”. It allows us to probe into this issue of unpaid work, which is very complex. Unpaid work is not only performed by parents who are living at home with their children and not working; it's also performed by people who work. It's performed while people work at home. You really cannot properly assess it by asking a couple of questions on a census.
The census is very powerful for looking at issues that have a meaning and importance for small areas. An example would be knowing where there are pools of labour, a labour market with people who have the appropriate qualifications to support such and such a plan for such and such a kind of activity—the small area data—or where to put a denominational school. The unpaid work data does not have a great deal of validity or usefulness at a small area level, so the census is not the correct instrument.
The question itself is vitally important. We have a better instrument, we do measure it, and we measure it very well.
