Hello,
I am an economist working on a research project analyzing contribution behavior on Wikipedia, and am interested in computing the fraction of individuals who use the site and make contributions. I have found the data on daily contributions, and am now looking for data on the number of individuals who use Wikipedia. I believe I have found the data I am looking for here:
https://stats.wikimedia.org/EN/TablesUsageVisits.htm
Unfortunately, the data contained in that file only covers the period from August 2002 through October 2004. Does a similar database exist for later time periods? Any information you can provide would be greatly appreciated. Thank you for you time and I look forward to hearing from you.
Sincerely, Nathan Marwell
