Linux has approximately 20x the download numbers of either Windows or macOS, and both Windows and macOS are pretty close together. These numbers are a bit confounded due to the fact that 1/4 of Linux’s downloads are made up of systems that don’t report their platform, so the actual ratio could be anywhere from about 25:1 to 3:1 in favour of Linux for either Windows or macOS. All of this is based on the downloads made in the last month.

Hmm. So it's really hard to know. Pity. I suppose it's too much to ask
for IP-based stat exclusion for the most commonly-used CI systems
(Travis, Circle, etc)? Still, it does look like most pip usage happens
on Linux. Also, it seems likely that the people who use Python and pip
heavily are going to be the ones who most care about keeping
up-to-date with point releases, so I still stand by my belief that
yes, 2.7.14+ could take the bulk of 2.7's marketshare before 2.7
itself stops being significant.

Thanks for the figures.
