Say 1.0% of them drink 1 cup of soy milk a day (on average that's probably not far off).
That gives 3,000,000 cups/day, which 700,000 liters/day
Now, per person, per year, that's 0.08 l/yr
So extrapolating that back, the study is saying that Americans consume 1.5 l/day, but I believe it means 1.5 l/yr.
This would give numbers more like 18% of Americans drink 1 cup per day or 1% of Americans drink 18 cups/day or 9% of Americans drink 2 cups/day, etc. I can see this being true.
So I believe the study is referring to number of liters per person per year, even though it says per day.
Like I say, it's a rubbish figure if it's worked out using the mean. I'd imagine most people drink no soy milk, whereas some people drink lots.
