I do think this depends on region, as I've seen F# and Scala jobs typically outnumber Clojure for example depending on whether it is a .NET or Java shop. Mileage does vary.
However to be honest anecdotally I do think even if they aren't going down in user terms, FP languages are losing percentage market share. From my personal experience FP is no longer new; the hype of FP in general has died down. The hype has moved onto other things over the years (e.g. AI, blockchain, bare metal technologies that enable the above, etc etc).
I'm not saying FP doesn't have a lot of value. I enjoy, particularly when the program calls for it, FP languages like F#, Scala, etc. They still offer a lot of value IMO for all the usual spouted reasons.
IMO I just think the hype has moved from technologies that do things better (i.e. more efficient, less error prone, makes my job easier, etc) to technologies that do shiny new things. There are a lot of reasons for this, many of them aren't in fact technical but economic and political (e.g. management). Things like less jobs globally in tech (meaning my skills need to have wider reach), demand for specialist roles that aren't as language focused, etc play a part. Mainstream languages taking FP features as well makes the return vs risk of using a FP language even worse of a tradeoff - there's less perceived return for changing stack than before.
