Certainly. First and foremost, it's the demand. We are seeing, because of COVID, a desire for people to have more open space, the kinds of facilities that allow them to combine a little bit of their leisure activities along with work and child care, and so on. Second, what we see are the interest rates. The mortgage rates are still at historic lows. I think that also gets people to.... All the components of our surveys are telling us this. Then we see the demand, in a sense, driving up a little bit of that price. Those are the main causes.
Again, I don't want to leave you with the fact that we don't capture asset price changes. We do. I think we've talked about the new housing price index and the resale price index. We calculate them on a slightly different basis from our colleagues in CREA and others. It's important to know that what we're talking about is an average price. What we're saying is that for a basket, if you like, of houses—single, multi-units, etc.—year over year, through the construction, the builders who are actually building them give us the information, and that's what the numbers are telling us.
It's slightly different, and it does feed into the CPI and the components that my colleagues have talked about. Again, you are shifting the concept, as has been mentioned, in terms of the asset or its replacement cost versus the cost to the consumer month over month. We do include the increased real estate prices, land transfers and insurance, and so on. They are included, but just from a consumption perspective.
