What is the actual percentage of people exclusively listening to vinyl vs digital?

I am, for all intents and purposes, 100% vinyl. 
I do have a CD player. I still have cassette tapes. I listen to them when it’s not available on vinyl. 
I don’t stream. 

And as for room treatments, mine is semi-anechoic. Walls and ceiling covered with rock wool and burlap. 

Who knows....Funny when I used to buy lps.i alway bought stuff on sale $3 to $5 .Then the Cds.found a guy who sold then $9.99 ....So how I'm not paying $39 to $49 for a album....Please.

By the time I was old enough as a kid to buy music, cassettes and boom boxes were the thing and cd’s were just a couple years away. So I never got into vinyl.

Now, back into audio last few years, vinyl just seems like too deep a rabbit hole right now with digital so good and so much further for me to explore on that trail now. But maybe some day when I get older and have more time.

Interestingly, my younger brother (low 40’s) has had a $500 Audio Technica TT for 15 years, and now has about 500 LPs. He doesn’t have a high end system (B&W 20 year old speakers line below the diamond and just a top cuurrent Yamaha AVR). I talked him into getting a Mani phono pre at least.

Anyway, at Christmas I sent a Cambridge 851n streamer dac that I wasn’t using home with him to play with.

Went to visit him a few weeks back and brought one of my unused power amps (Edge W) with to swap in.

First we listened to his setup, and even with my more expensive 851n digital his TT sounded better through the AVR.
When we ran the 851n dac direct into the Edge W, bypassing the Yam, the digital pulled ahead. For some reason the TT through the Mani thru the Yam as preamp to the Edge W didn’t really click.

But anyway, to wrap this up he said for convenience he listens to 80% digital but when he is in the mood for analog the 20% of time he enjoys that most, but carving out the time to be in that mood is the issue

There are verifiable statistics to guide us. In Jan. 2021 vinyl album sales were 27% of all record sales. It's only gone up since.

We're all audiophiles on this forum so we don't care about the invented "Album-equivalent unit" term marketers use to determine the listening habits of those who listen to music on their phones or computer speakers but audiophiles have always been a very small % of the overall market.  Of them however & that group adjacent, buying records in physical forms, vinyl's growth is literally exponential & is on track to eclipse CDs (in the next couple or few years somewhere).  Downloads & streaming complicate things of course but there is a fundamental attraction to the physicality of records & ever larger numbers that once they've heard analog done right cannot easily suppress & deny the reality of the depth of the experience being greater.
