And so on...
Numbers show that at the time each of those things was true (strange coincidences), but part of it was involvement within those circles changed my perception as well and skewed it a bit.
This is a good point... also, for the most part, it seems as though you have to seek out other homebrewers. It's not a very common thing (at least near me) in the public spotlight.
I feel like here in NY it's still a secret basement operation, probably to keep it from growing too rapidly. Although as Revvy mentioned, the Whole Foods here does have ingredients, and I do buy from them. However, I haven't once seen someone even look into the homebrew corner... I could probably sit on the floor without being disturbed.
So to the original question... it's hard to gauge, and probably varies significantly by region.
