At this moment it has 720! And this seems to be roughly the norm recently. - Jake McArthur

No one knows. There are many figures that you could use to estimate the size (e.g. I try to gather signifcant stats in yearly reports about Hackage) * In 2010, for example, 138,000 unique IPs downloaded the Haskell Platform. http://www.galois.com/~dons/talks/hiw-hackage-y2.pdf -- Don

Right 138,000, but that would not account for gateways :| Aaron

Then there are people who download it, look at it and maybe find it too complex to use ? I am wondering if mailing list statistics would be the best guide ? Aaron

Many people don't subscribe to the mailing list, and instead read it on gmane, or google, or reddit, or follow the stackoverflow site, or ... E.g. 6500 people follow Haskell on Reddit. How many Haskellers don't feel the need to read daily news about it? -- Don

All the answers made me wonder what the criterion is to be a member of the Haskell community. Are you a member if you downloaded ghc, if you have (at least once) defined a Monad instance, if you have written a hackage package, if you have contributed to the Monad.Reader, if you have a github account with at least one Haskell project, if you read at least one of the haskell mailing lists, if you contribute to a haskell mailing list (perhaps on a regular basis), if you post on reddit, if you answer/ask questions on stackoverflow, if you have written at least 10000 lines of code in Haskell, if Haskell is one of the programming languages you use, if Haskell is the one programming language you use, if you have written a PhD thesis related to Haskell, if you have asked a type related question only Oleg Kiselyov was able to answer, if you know what a Monoid is and know how to use it ... ; ) Cheers, Jan

Maybe we should have some website like the Linux Counter where you can get an official Haskell user number ? Then advertise it well. Aaron

Well, Haskellers does have an "official" number for each registered user, but since it's using OpenID, the definition of "registered user" is a little hazy. Basically, anyone who ever logs in will get a number assigned. So I would not trust the count of total "accounts" for anything other than people who have taken some form of interest in haskellers.com. On the other hand, Haskellers does give a count on the home page of 495 public and 145 private accounts, and I *would* consider those numbers to mean something: it gives a lower bound to the number of people who are interested in Haskell enough to join a site for Haskellers. In other words: it doesn't tell us much more than we knew already. If there's interest in trying to get a more accurate count of "active" Haskellers[1], and people think haskellers.com could help somehow, let me know. Michael [1] For some definitin of active Haskeller.

I've been subscribed to this list since the very start of the 2010 year, and I counted 1168 ± 20 different persons posting to this list (I just listed all the mail from Haskell-Cafe in my mail client and after 1.5 hours of work I counted them all, so I can be slightly mistaken). As only 1/2 of all haskellers post to the Cafe, and as I'm novice, I missed... OK, 6/7 of all haskellers (the number of haskellers grows over time, so there was little of them 10 years ago), 1200 * 2 * 7 = 16800 haskellers.
