I was wondering about how representative this is of the populations. The link to the survey is broken but I did find this on the Ipos Mori site:

> The remaining 11 countries surveyed: Brazil, Chile, China, India, Malaysia, Mexico, Russia, Peru, Saudi Arabia, South Africa and Turkey have lower levels of internet penetration and so these samples should instead be considered to represent a more affluent, connected population

I would extend that consideration to most of the countries shown in the results.
