There's been one study of income replacement rates done at Statistics Canada. It came out last year. I've brought copies for the committee that I could leave with the clerk.
On that one, the family was the unit of analysis. Because the majority of women are living within a marital couple, they looked at family income. As for disaggregating that in terms of women living alone versus women in couples, we haven't gone that far. As I say, we've only done one study on the income replacement rates, and only now are those longitudinal data becoming available to do that type of long-term analysis.
