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

You can not be equivocal about zero.
One lone fanatic out of an infinite sample size IS NOT absolute zero %.

How did this idiotic question turn into blather about preferences?  Every person is entitled to like whatever they do, faulty reasoning aside.

I have been on a forced vinyl holiday going on 4 months now. I ordered a new turntable directly from the manufacturer, sold the old one and to have Covid hysteria slow turntable production down to a crawl. I have been listening to a hard drive and the few assorted discs, maybe three hundred I have left. There are almost 4000 albums on the hard drive so it is not like I am starved for music. But, I am starting to develop withdrawal symptoms. Looking back I do not think I have gone this long without playing a record since I got my first record player in 1958 for my 4th birthday. 
I just want to play a record. I do not think it is because of any sonic difference either, more like the intractability of old habits. 
This argument over formats is getting rather old. The digital formats are unquestionably more accurate by any and all measurable parameters, playing records a measurable disaster. What can't be measured is what they sound like. Beauty is in the eye of the beholder. This is why I personally do not care what people think anything sounds like. Unless you know the person and their tastes very well there is no way to control for it. 
So, what we have is an argument over what color is best in an unknown décor. Seems sort of silly doesn't it? 

My son (a college kid) and some of his friends buy LPs. They buy many LPs from new artists that many of Agoners may have never heard of. Some of them cost A LOT, over $50, or even over $100. We are not talking about 1st press Beatles or 50/60s jazz albums.
Do you imagine listening to Kanye West’s music in LPs?
An interesting thing is, those new LPs sound just like CDs or even streaming, and I ask my son why he buys LPs. He says, it is cool to play vinyls, and maybe for investment.
For me, about 60% vinyl and 40% CD/streaming.

vinowino,
Try buying a good CD player and you might feel differently.

I listen to vinyl exclusively. I don`t have the will and the money to buy any DAC or CD player what would be comperable to my TT and cartridge (Ikeda 9TT). I rather choose one format than dealing with the additional problems (cables, space, rack etc). Budget purist only option is vinyl.    R2R would be even better but I don`t have that kind of money. But I envy people would settle with less. If convinience would have the priority I would only stream. D-class integrated amps are pretty good nowadays and a pair of Voxativ speakers with subs would do excellent job. A really good vinyl setup with selected LPs would always beat every other format than R2R. Does it worth those 1000s of hours and money? The other one is just plug and play. Even the room correction is done. I am tempted too, but it just doesn`t sounds that good and I have the will and the passion to chase the magic dragon.
