Today, Google said that there were 40 million Chromebooks in use in education worldwide, a jump of 33 percent over last year, when there were 30 million users.

“We launched Chromebooks 10 years ago to reimagine what personal computers could do, so we set out to create devices that champion speed, simplicity, and security,” Google’s Jim Deno writes in a post timed to this week’s BETT 2020 show in London. “Forty million students and educators now use Chromebooks, and we’re still listening to them every step of the way.”

That figure may be more comparable to Windows 10 PCs in education than you think. Microsoft said last week that there were “over 100 million students now learning on Windows 10 PCs.” Since multiple students use each PC in many cases, Chromebook and Windows 10 PC usage in education could be very similar.

Google didn’t provide any other hard numbers—last year, it also talked about G Suite usage growth in education, for example—but an animated chart shows how Chromebooks are penetrating education markets worldwide over time. And some regions—including the U.S. and Canada—actually experienced 60 percent growth (presumably over time). Chromebook usage in western Europe, Australia, and New Zealand has been about 30 percent.
