English: Timeline of anonymous article edits on English Wikipedia. By percent. See box of explanatory text on the chart. The box of explanatory text lists the total cumulative number of article edits (in millions) by anonymous editors for the period covered by the timeline. More current charts are needed.

See also the top left of the chart: "100 = max anon edits in Mar 2007: 1665735". There were 1,665,735 anonymous article edits on English Wikipedia in the month of March 2007. That was the largest number for any month in the timeline.

There were a total of 4.8 million article edits on English Wikipedia in the month of March 2007 from all sources: anonymous, registered, and bots. That is from Wikipedia Statistics - Tables - English. See the "Database" header, and then the "edits" column. That column shows monthly article edit totals (including redirects) going back all the way to Jan. 2001 when Wikipedia started. Note: Bot edits need to be separated out since their totals can vary greatly month to month. Separate columns are needed for monthly edit totals for registered users, anonymous users, and bots. This link goes to the section concerning anonymous contributors. It states: "No detailed statistics for anonymous users are available for this wiki (performance reasons). All together 109,370,998 article edits were made by anonymous users, out of a total of 366,162,033 article edits (30%)" That is what it said on June 30, 2013. Those are totals since Wikipedia started in January 2001.
