The data breaks down significantly more than that and it’s stating that the majority of those fans are Boomers or Gen X. Typically, advertisers (who help pay for this content) go after adults ages 18-34. (However, that is being expanded more to 18-54.)
The data doesn't show that at all. The breakdown is 38% Boomer, 39% Gen X, 40% Millennial, and 33% Gen Z. So other than a drop off among the youngest adults, Trek is pretty stable in terms of the self-identified fandom.
Of course, figures are more age skewed when you look at who's actually seen an episode of any Trek show. 80% of Boomers have seen TOS, only 25% of Gen Z. But it's important to note that for Kurzman Trek, despite the smaller audience, they skew younger. Only Picard skewed Boomer/Gen X (for obvious reasons), with SNW having basically equal levels of fandom across all generations other than Z, and Discovery, Lower Decks, and Prodigy all skewing millennial.
That said, the overall diminution of Trek's fanbase over time is clear here. Discovery reached 11% of adults, which is tied with Enterprise (which is still way behind the other Berman Trek series, which are in turn behind TOS). Then Picard was a bit lower at 9%. Lower Decks, SNW, and Prodigy only reached 4%. So you can see why they pulled the plug, as each show was hitting a smaller and smaller proportion of the original Trek audience.
I'm not sure this is unique to Star Trek (my understanding is the MCU and Star Wars suffered the same fates in modern streaming, with diminishing returns with each new outing), but to premier yet another show which gets a fraction of the audience of the shows preceding it just doesn't work.
Interestingly, we see the same general trend with movies. The Kelvinverse hasn't been seen by more than 13%-14% of people, which is way less than either the TOS or TNG movies. This might've been masked a bit when looking at general box office, as they were viewed as financial successes, but this didn't take into account how theatres track total box office, but not tickets sold.
Also being self-defined doesn’t suggest what audiences pay for. The franchises I’ve named are far more lucrative than Star Trek. Harry Potter has brought in $35.1 billion, Batman itself $29.9 billion, Transformers $25 billion.
Star Trek, on the other hand is less than half of the lowest of those franchises, only bringing in $11.2 billion. Comparatively, that’s fairly niche. (

So there might be more fans (although I’ll wait for an actual source to say that’s true), but the other franchises have brought in more money.
I agree with this broadly, though I'd give the caveat here that these totals are not inflation adjusted, and include things like merch. Obviously something like Batman and Transformers will beat the pants of Star Trek, because 8-year-olds aren't playing with Picard action figures.
That said, just because Paramount was unable to figure out how to monetize Star Trek for the many casual fans who didn't care enough about Star Trek to check it out on Paramount Plus, that doesn't mean that it's impossible - and it doesn't mean that Skydance won't try and figure out if it can right the ship here. I mean, it's the job of studios to figure out how they can make money from things, rather than just throwing up their hands and saying nothing can be done.
