I think India data is showing not correctly!
https://caniuse.com/#feat=css-featurequeries

I think it would be 97 not 87
PS: Indians don't use IE and my calculation says it's surely not 87 in any case
Agreed, there's something weird going on. Currently 11.4% of India's data is "untracked", a month ago it was only 5.1%. I suspect it relates to a recent change in the StatCounter data, though curiously data from other countries appears to be correct. Will let you know if I figure anything out.
Wait this might be because of this phone, https://www.jio.com/en-in/book-jio-phone
This phone has got popular from last 1-2 months due to it's very cheap price
It's using KaiOS => http://www.kaiostech.com/
More researching made me found it's actually forked from one and only FirefoxOS
Yes that discontinued FirefoxOS ... but it's still alive
The Boot 2 Gecko community is maintaining this open source operating system now!

WOW!
Thanks @Fyrd for the tracked update... Really thankfull!
Seeing some incorrect country statistics:

I'd expect that CSS Grid has broader applicability than 60% of browsers, and I'm certain that we have more than 0% use of iOS 12.2/12.3 in the US and Australia. Similar numbers for flexbox etc.
@inopinatus Thanks for pointing that out, have fixed it now! May need to reload your browser.
