I'm just curious: how many users are there on Stack Overflow altogether?

  • 240,975 users thats massive :))) well done stackoverflow – getaway Sep 22 '10 at 11:59
  • why is this a bad question? its honest and clear – Mike Sep 22 '10 at 15:36
  • after running a subquestion on my own- It seems that the last answer is the only right one since it balances out the deleted users and is constantly being updated - rather than the answer you adopted which is the least accurate! – noawithouth Feb 3 '13 at 17:40

You can find this and more information at the StackExchange site list.

As of a few moments ago, StackOverflow boasts:

  •    21 million questions
  •    31 million answers on 70% of the questions
  •    14 million users
  •    10 million visits per day
  • I think this number is exclusive inactive users. The total is then about: 455K users, 345K active, 241K registered. – BalusC Sep 22 '10 at 12:31
  • @Balus -- Yeah, so? :) Besides, what keeps a user that has been deleted for inactivity to then reregister? What about merged users? What about spammers' sockpuppets? – badp Sep 22 '10 at 12:33
  • You need to read "users" as "accounts". – BalusC Sep 22 '10 at 12:34
  • how did you reach these numbers about the non active users? – noawithouth Dec 6 '12 at 22:35
  • New amount of users: 2,015,270 – noawithouth Feb 3 '13 at 16:58

Go to the Users page, tab to the Newest, peek the user ID of the latest user (it's in the URL if you peek/click the username link). Currently it's 454993. This includes registered, unregistered and inactive users. The Users page itself only shows registered users.

  • -1 that includes deleted accounts. – uɐɯsO uɐɥʇɐN Sep 22 '10 at 19:04
  • @George: that falls in the "inactive" category. Those users with some default lightgray face-avatar and without a profile page. Or do you have a different definition of it? – BalusC Sep 22 '10 at 22:18
  • 1
    Regardless, deleted users are not users. – uɐɯsO uɐɥʇɐN Sep 22 '10 at 23:13
  • The method I outline in my answer gives a more accurate number. – uɐɯsO uɐɥʇɐN Sep 22 '10 at 23:14

I doubt very many. stackoverlfow.com looks like it is being squatted by a redirect to a job search engine, while the more original stackoverlow.com is registered to one of those "search portal" sites that automatically names itself after the domain (the look and layout is also randomly chosen on each load).

  • Thanks for that, I fixed the typo. – badp Sep 22 '10 at 12:18

As of 22nd September 2010 there are 6885 pages of users with 35 users per page.

Given that the last page won't be full there's between (6884 * 35) and (6885 * 35) registered users.


The best way of finding this out is to use the API:


According to the page, there are 344,686 users.
