I'm not sure if this is a direct answer to your question, but I think one of the strengths of the census data is the mix, the range of information. It might not be the most perfect unpaid work question, it may not be the most perfect job-related question, but the elements are all there. The various range of things we've talked about in terms of immigration, paid and unpaid work, incomes and family incomes, and children and education--it's that mix that's really important.
