Size of Wikipedia community

The relevant number is 129,861 active editors, and about half spend at least an hour a day editing.

I hope to join in more.

Studies of the size of the community of Wikipedia showed an exponential growth in the number of Wikipedia contributors during the early years. In April 2008, writer and lecturer Clay Shirky and computer scientist Martin Wattenberg estimated the total time spent creating Wikipedia at roughly 100 million hours.^[2] In November 2011, there were approximately 31.7 million registered user accounts across all language editions, of which around 270,000 were "active" (made at least one edit every month).^[3]

As of today, the English Wikipedia contains 5,130,300 articles – the cumulative product of 28,032,265 registered editors, and an unknown number of anonymous contributors. There are 129,861 active editors on the English project. Wikipedia editors continue to increase the number and length of the articles. About half of the active editors spend at least one hour a day editing, and a fifth spend more than three hours a day.^[4]
