Yep, sorry for misleading you. But in general I think the usage is about similar in the city of similar size in the same country.
From what I hear from operators Canada and US are quite similar in usage.
And it is more depends on the location itself and done promotion, here are the average figures I know at the moment.

Usage:
buy ~90% vs. sell ~10%
In very volatile price market these proportions change quickly, but then return to about these figures in stable market.

Volume:
An average machine at average location gets about $20-30K volume per month.

Average transaction is about $200-400 from what I know, but the distribution might be skewed with many small and several significantly big ones. There are about 50-70 users per month.

These are kind average figures for average location in developed country (Europe and North America are quite similar in figures).

However, I know locations where more than $100K was done per month, although there are definitely some which even didn't make return on investment. It all varies.
