There are two concepts here. One is how you measure the change in that basket as exemplified by that typical expenditure. It just says that in terms of shelter costs, we're talking about an average household spending about 30%. That serves as the weight in the basket, and then you see that change over time. Year over year, it has gone up 4.8%. I think I talked earlier about the different components of what that means.
This whole notion of a percentage of the income of a household is a separate measure, and that's where I was going in terms of the core housing needs. We do measure that as well.
