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

Well since I'm in both listening camps (records and CDs), I've accumulated another 8,500 LPs in the past 3 years by buying two estate collections and being gifted another (all from deceased collectors).   I rarely seek records in stores any longer as I have 28,500 LPs/7,000 CDs/7,000 78s.  As to CDs, I occasionally go to thrift stores and often buy on line, mostly jazz and pop with many bargain cost classical music boxed sets.  Life is too short to go after one or two records in stores.  When I shop, I go to a store with good turnover and inventory and luckily live in Los Angeles.   NYC's record stores were mostly gone in 2018 when I last visited.   Most L.A. stores are very reasonably priced unlike NYC which profited from tourist buyers.

100% Digital (CD/SACD) here.

Happy Listening!

 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.

That study also says that vinyl accounts for only 3.6% of music consumption.

Which reflects the problem with tracking album sales the last couple of years - a lot of us who were buying dozens of CDs per year are now streaming and don't buy any albums at all. I even bought 400 Bandcamp albums (including a 200+ Buckethead Pikes set) within a four year period up until two years ago. Now we just rent a service instead. So it's not necessarily that vinyl sales are exponentially growing compared to digital, but that streaming rental is taking away its statistical competition.

@fleschler - #1-do you have these 28,000 categorized in a spreadsheet? Is this part of a record store you own?

#2- do you have them in their own special room or climate controlled garage?

#3- how many do you listen to with any regularity?

#4- how many are NM or audiophile quality and how many are $1 or less junkers you never listen to that just take up space and add to your totals?

I have been accumulating vinyl over the past 40 years (of course with the break from the late 80’s until the early 2000s when nothing was produced really) carefully, 97% new, all in NM condition with very few exceptions, and I have 300. There are a small % 10 or less that I almost never listen to and still I may not hear an album for months. I probably listen 15 hours a week on average. The most I’ve ever bought at once is 3-4 with the exception of The Beatles MFSL Collection, which has 14. 
Just curious. I can’t think of anywhere over 1000 that I would even consider, but I have no classical, hiphop or rap, unless you count the Moody Blues Days of Future Passed on MFSL.

1.  A. I have 15,000 LPs/4,500 CDs/2,000 78s categorized (not on file cards any longer) on my computer. 
B. I do not own a record store.   I have sold 18,000 records in past.  I have a rule once I hear a record, if I won't potentially listen to three times annually, out it goes.   If it has low musical merit and mediocre sound, out it goes.
2. Also, the LPs, 7,000 CDs and 4,500 78s are stored in a climate controlled, storage room located adjacent to my main listening room.  The remaining records include are stored mostly in stable temperature storage shelving in a storage shed and several garages.  They are kept dry and clean.
3.  I listened for 2 hours on Friday and 2.5 hours Saturday.  I switch off between CDs and LPs on the same day or alternate days, depending on what I want to listen to.  I have become lazier and listen to 78s less often.  30% of my 78 collection is ethnic music which is mostly unavailable on LP or CD.
4.  A. About 75% of my LPs and 50% of my 78s are in NM condition.  Nearly all my CDs are NM and play M.  As to being junkers, I don't collect junkers.   I do have in storage, NM condition multiple duplicate opera LP sets (1000?) which probably have a value of $1/LP.  They were either gifted or purchased really cheaply.   I have for example, a collection of 300 RCA Living Stereo and 100 Mercury Living Presence, 150 London/Decca, 100 Audiophile Label, 100 MGM LPs which I have not cataloged and are on shelving across from the main collection.   I pull out listening LPs from both the cataloged and uncataloged (but in numerical order) sections (and put them back where they belong).   I don't know when I will get to the non-listening room records,   
B. I listen 2 to 2.5 hours per night to music, sometimes more on weekends and now able to share music listening post pandemic.  That's a lot of fun as well as reading.  I have 3,500 books and periodicals in two libraries and read/scan three newspapers daily along with TheDailyWire and FoxNews (I used to be a Moynihan/Jackson "liberal" in the 60s and voted for Clinton and Gore but that changed with Obama/Biden).  
C. I am married with no children living at home.   My wife is usually busy with her toastmaster hobby (an former international governor of the year) teaching and on zoom meetings while I indulge in my music listening and reading.
D. I began collecting/listening when I was 2+ years old with 300 records by age 5 (my parents indulged me with "junkers" and cheapy records.  
E.  I moved two years ago to a nice size home (5,600 ft) to store and enjoy life now that I'm 65.  No congestion with separate rooms and libraries.
