You're absolutely right that the residential investment in real estate as a proportion of the overall [Technical difficulty—Editor] quite a bit. Unfortunately, the other factor that you talked about, the business investment, in general overall has gone down. So you see one going up and the other coming down.
The net worth of Canadians, as those real estate assets have gone up, has also gone up. I think we showed that it went up by about $2.3 trillion as well. Those are all stats we put out that talk about the change and so on. They talk about that asset and how it's in proportion to the overall economy going up or down over time. That's assets. CPI is consumption. [Technical difficulty—Editor] an average household in a particular area would now incur to maintain that asset, if you like.
That's what the CPI does. It takes a basket and it shows you, okay, when you purchase that home, and you pay the real estate fees and the costs, that's included. It includes all those elements that are the one-time costs, but then it says, quickly, what are the costs to maintain that particular dwelling?
The CPI is a consumption-based measure and the other is an asset-based measure. They both exist. We track them both.
