Alt, I used to have that "map" as a desktop picture.
A nice composite of shuttle photographs. Interesting how in many places you can see the outline of major highways with bigger cities laying on that route.

I don't like it how National Geographic makes you take the test if you want to see detailed results, which you see only for 20/56 questions, and then after you're done doesn't offer a real report of the results, just some "highlights" I do like to look at results and procedures of polls in detail (maybe because I took statistics classes?). But maybe they'll try to sell the full report.
The timing of the release of the results does look a little suspect indeed. On the other hand they do seem to be trying to make something about it, from a cursory look at some of the sidebars and links provided in their news item on the poll. BTW, I think that asking the population of the US does not properly belong in a worldwide test (more proper if it was replaced by or accompanied a question about the population of the home country), and it's not really a geography question. Got right 18 or 19 out of the 20, BTW, but that does not erase the shame that my compatriots cast upon all of us.

Sue (or anyone else) I didn't know there were other Latin American wombers, certainly I'm unaware of any active South Americans (come forward if you're out there! and apologies in advance if your presence has escaped my memory).

Maybe we should get a map created pointing out the location of all wombers, that would bring greater geographical literacy to us!

P.S. Grantley, the 1/7 thingy was, I'm sure, more than an error a way to approximate the 13% for those people that are math illiterate in addition to geography illiterate. And 1/7 is more like 14.28% actually. :) Journalists can be so imprecise sometimes, but I can certainly understand the motivation to put numbers into ways that would make it more understandable and have more impact to most people (it's the kind of things a researcher sometimes has to do).
