last i checked elves were very explicitly doomed to fade away as magic left middle earth, and what with it canonially being our reality in the past and us now having 8+ billion humans alive, how many elves were there at the last point in time depicted in the books? It feels pretty safe to say we outnumber them now, at least.

Also makes me wonder what's supposed to have happened to dwarves, i think hobbits just interbred with humans until everything kinda evened out but did dwarves do that too? must have been a bloody slow process considering.. everything about them..
