The lens package on hackage has almost 63000 downloads. I think this
is probably a good approximation to the number of serious haskell
*installations* because even people who don't like lens probably have
downloaded packages that depend on it. I suspect that very few
serious haskell programmers don't have lens installed. (Packages that
ship with the platform, OTOH, won't get counted enough.)
Of course, this is not a good approximation for the number of haskell
*programmers* because many people will have multiple installs going.
For example, I have 4 installations (3 work + my laptop). It's
probably best to think of this number as an upper bound.
If we assume that haskellers have on average two installations, then
we would come up with about 30000 haskellers.

Hi,
more numbers: Of the roughly 150k machines taking part in the Debian popularity contest, 4936 (3%) have GHC installed, and but only 898 (0.5% ) use it: https://qa.debian.org/popcon.php?package=ghc
And that might include some xmonad users that you wouldn't necessary consider Haskell programmers.
Users of xmonad and pandoc certainly add up to that number. Cabal-install would be a better reference than GHC, with 1467 (0.8%) users have haskell-platform installed: https://qa.debian.org/popcon.php?package=haskell-platform
