These stats are absolutely inaccurate. According to their FAQ:
"We do not manipulate the data in any way. We do not collate it with any other information sources. No artificial weightings are used. We simply publish the data as we record it."
Yet, 25% of their hits are recorded in the United States. Their recordings are not distributed in a same way users are. Data should be weighed up/down according to how much data they got from a region, how many people live there and what is the Internet penetration. I think that the graph (and not just this one) would look VERY different. Conclusion: Title is misleading. You can't say something is world's whatever when you have data from four countries.
edit: Inaccurate in the context of how they are interpreted.
Thanks for your comment. I'm from StatCounter and would like to address your concerns.
Weighting stats means that the stats are only as good as the weighting methodology used. If the weighting data is inaccurate or out of date, then it renders the data completely incorrect. For these reasons, we choose not to weight our data in any way and instead we report is as we record - other commentators can, however, weight the data as they wish.
I'm not sure why you think we only have data from 4 countries. We have a very large global sample size of over 15 billion hits a month. You can view the country break-down here: http://gs.statcounter.com/faq#sample-size
I understand that it is not really possible to make it perfect. And I also understand why you share raw data and it's probably the best way to do it. I just wouldn't make such strong conclusions from it.
