The total edit count for all Wikipedians combined was reported as having reached one billion in mid-January 2021, with the billionth edit being registered by the most prolific non-bot Wikipedia editor, Steven Pruitt, though it was also noted that several hundred thousand early Wikipedia edits were lost in a software upgrade. Notably, some of the highest edit counts in Wikipedia are achieved by bots running automated tasks, rather than by human editors. Among human editors, it has been observed that a small percentage of editors are responsible for a substantial proportion of the total number of edits that have been made.
