Wow. Chrome outnumbers MSIE on Windows? I would not have expected that. (I mean, I would not have expected to see anything ahead of MSIE.) In concrete terms, using their 34.5% figure, that means fully 2/3 of Windows users have gone to the trouble of downloading and installing an alternative browser. Though I do wonder what proportion of them truly realize that Chrome is a browser rather than just "something to make Google run faster".

What the heck is Edge, anyway? I thought it was just MSIE in new clothes. Oops.

I'd beware of taking this too seriously. The data is accumulated from a specific niche (gov) and may not scale accurately across the entire web. As a cross section of a specific niche, however, the numbers are very intriguing!

I'm also surprised at the high use of Chrome for Windows. Do any Chrome notebooks or Android tablets run Windows or is this all desktop?

We discussed this before I think. The data from this site was arguably a pretty good indicator of general use in the US. Although it is from .gov, a large portion of the US populace goes to .gov sites for things like tax filing information. It's probably less niche than some tech news site displaying the same stats. They're pulling from a wide variety of .gov sites IIRC.

Although it is from .gov

It may even be more accurate to say “because it is from .gov”. Any website you can name has its own demographic; it's what you tell the advertisers. But some sites, everyone's got to use sooner or later.

That's assuming their information isn't strictly from, say, the Social Security Administration, where nobody goes until the week before they absolutely have to. (Does everyone go to irs dot gov? You'd think most people have to, sooner or later.)
