How many Furyans are left?

Excuse me, could you please elaborate on the current status of the Furyan population? Are we talking about a specific group, community, or perhaps a species in a fictional or non-fictional context? If it's the latter, has there been a recent event or development that has led to a decline in their numbers? And most importantly, what are the current estimates for the number of Furyans that are still alive or present? I'm genuinely curious about this information and would appreciate any details you might have.
