As of 26th August according to CanIUse.com, ~1% of users globally use either IE8 or IE9.

I know of institutions and research-heavy rules dictating use of IE only on low-end computers. No third party browser installs, ironically, stating security reasons and low-end computers due to unavailability of funds for hardware upgrades.

Plus not to forget some domain specific communities, e.g. research graduates who have access to outdated desktops only.
