About the Wikipedia survey, the astonishingly high percentage of contributors is counted from the population of "active-users", not from the "general audience". In the latter case, the percentage would probably be significantly smaller. The authors themselves wrote to their preliminary results : "Since it is impossible to quantify the universe of people using Wikipedia and how many of them are contributors it will be hard to evaluate whether the shares we found in our survey are representative."
