I think that there is a real split between consumer and corporate at this point (certainly in the West). Some managed corporate setups are definitely still on old versions of IE, but for everyone else, the path of least resistance has been auto-updated platforms for a while now (Windows 10 + Edge, iOS, Chrome, Firefox).
Recently, I updated the browser support docs for my employer, and was surprised to note that IE11 is now the oldest browser with standard vendor support, so everybody on older versions of IE is either working for a company with specific extended support contracts with Microsoft, or they are running with no support at all.
