I'm guessing you meant to say "use their credit card but elect to use it as a debit card"? Otherwise I'm not sure what you mean. And no, I don't think they do factor it in, for statistics like those.

It's interesting though, how large differences between countries can be in terms of which banking products and services are used. For instance, in Belgium, checks are hardly ever used, compared to the US, but that isn't by any means a European thing, as the French for instance use them all the time as well. And while it's rather self-evident to most people here to pay things like rent and other non-varying recurring bills through automated monthly bank transfers, in other countries that's rarely done.
