FWIW, Google Trends shows the hype peaking in 2016, but I doubt that reflects usage as much as buzz.
Instead, if you look at the annual State of Clojure survey results, which solicits opinions directly from the community, the number of responders peaked in 2020 at ~2500, and is down to ~1500 for the most recent 2024 survey.

Now... If we are pointing out isolated facts to make an argument, I would caution that survey popularity (sensitive to timing, duration, outreach etc.) is less telling---and less statistically significant---than isolated facts like this:> Clojure versions
> Clojure 1.12.0 was released in September 2024 and the survey showed rapid uptake, with 58% already using it, and 65% developing or deploying with the prior versions 1.11, and a steep drop-off after that. Clojure’s focus on stability and avoiding breaking changes makes upgrades safe and easy.
> Trends (use at work, hobby, and study have all up-trended)

> Because this survey has been running since 2010 (thanks to Chas Emerick originally!), we have lots of great longitudinal data and it’s interesting to compare some of the answers over time.
> Looking at the question of how Clojure developers use Clojure, we can see this has generally trended more towards using it at work. However, this year we saw an uptick of people using it for hobbies or in their studies:
Look for the number of responses, and you can see a decline each year after 2020.

It's possible that the survey may not have been advertised as well, but afaik, it's still posted the same way it always was: announcements on Clojurians, Clojureverse, reddit, etc. I haven't heard of any reason that survey numbers would have been artificially depressed for several years running.
