Earlier quoted context omitted.
I guess I'm just curious about how far off we're talking about. Is it accurate by country? Accurate by general region if not the entire state? Depending on the purpose you're using it for I'm just wondering about the accuracy level for sake of "good enough" uses.
I would guess that it is accurate at the continent level.
In terms of accuracy, it is generally very accurate on a country level. Anything else is pretty useless.
