That the UN doesn't break down the United States in to high-tech regions. So 'North America' would lump together 9 regions in the list above each with a different taste.
The poll is basically a US centric poll with the rest of the world thrown in as an afterthought, unfortunately that's a pretty accurate representation of the way many tech people see the world.
This actually causes a feedback mechanism that now means that being located 'in the valley' translates in to a very real competitive edge.
Wait, for me there's nothing wrong in narrowing specific regions (such as US or even silicon valley), but the rest (like dividing Europe into west, east and other) leads to confusion, not to mention that forgetting South America is pure ignorance.
