Fantastic overview of all the new emoji in iOS 9.1 by Emojipedia’s Jeremy Burge:

In addition to emojis approved in Unicode 8.0 (mid-2015), iOS 9.1 also includes emoji versions of characters all the way back to Unicode 1.1 (1993) that have retroactively been deemed worthy of emoji presentation by the Unicode Consortium.

Every emoji that has been approved by Unicode is included in iOS 9.1; no matter how obscure, redundant, or outdated.

The article includes this bit about the Symbols category of the updated emoji keyboard:

Symbol emojis are grouped by color in iOS 9.1, which not only looks pleasant, but also makes finding the correct emoji easier.

Like millions of other people today, I’m having fun discovering the new emoji in iOS 9.1. Jeremy’s overview makes for a great starting point.
