I disagree with this. Having lived in the US my entire life (specifically MA and VA), I've been in very few homes that had chest freezers, and as far as I recall, none that only had chest freezers (as opposed to extra storage beyond a combination refrigerator/freezer).
I'm not willing to pay to resolve this difference of perception, but if one wanted to do so, the information is probably available here.
Here on the West Coast I've seen both standing and chest models, although combination refrigerator/freezers are far more common than either. I associate the chest style with hunters and older people, but that likely reflects my upbringing; I wouldn't hazard a guess as to which is more common overall.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
