I'm involved in two gaming groups regularly.
Demographics for my 3 gaming groups are similar.
To me, the obvious demographically unusual characteristics are: only 1 in 16 is female, 14 in 16 are white, and all are currently employed. But most of them being smarter than average is also clear, to me at least.
None of us are 1%ers in the "Occupy" sense (99th percentile income). Not even the entrepreneur (all the money goes back into the business) and probably not the surgeon.
Group 1 (email, I'm the DM):
-- Player 1: Never finished college. Works as a repairman/janitor at his church. Deeply interested in history. Navy veteran, tested as 99th percentile IQ on ASVAP (US military test). Married, no kids.
-- Player 2: #'1s wife. MBA, works in HR consulting. Studies the Civil War for fun.
-- Player 3: Computer consultant, former minor league baseball player. Married twice, two kids.
-- Player 4: IT guy working on a government research project that just got national TV coverage. Graduate of the top rated US college. Married, no kids.
-- Player 5: Co-founder of a 200-person software company. Expert on military history. Graduate of the top rated US college. Married, one kid.
