Not sure if this question belongs here but I want to give it a shot.

I need to give a presentation about Q&A websites and, of course, I cannot do this without mentioning the Stack Exchange community. I wanted to show some statistics about Stack Exchange and mention how many questions are asked every second (or minute).

However, I looked around but haven't found a good answer.

Can someone point out to me where I can find such information?

Expanding on the answer by Shadow Wizard: of course we can add numbers in JavaScript, even without jQuery. Navigate to stackexchange.com/sites and paste the following into the browser console:

l=document.getElementsByTagName('input'); s=0; for (i=0;i<l.length;i++) {if (l[i].name=='questions-per-day') {s += parseFloat(l[i].value,10);} }

This returns the number of questions per day across the network (averaged over the last two weeks). Current value: 9739.35714285715. Divide by 24, then by 60: the result is about 6.76 questions per minute.


One can also study fluctuations of the rate of asking (and answering) throughout the day by using API. For example this API query currently returns for Stack Overflow:

"answers_per_minute": 4.22,
"questions_per_minute": 2.45

These are updated about once per hour, if I understand the API documentation correctly.

  • You can use jQuery, it's included in all pages and the console has the page context. – Shadow The Burning Wizard Jul 22 '14 at 20:52
  • @ShadowWizard I originally wanted to, but decided not to, out of sheer principle. :) – user259867 Jul 22 '14 at 21:12
  • Fine, make your life harder by choice. :-D – Shadow The Burning Wizard Jul 22 '14 at 21:20
  • Oh, I see how it works. No jQuery & no freehand circles => 1 upvote vs 10 for the other post. (And that 1 probably was Shadow himself, a known good sport...) – user259867 Jul 23 '14 at 4:06
  • I think you just cracked the super secret Meta formula of voting! Or, maybe Meta dwellers simply don't like scripting, as this awesome script of mine got a meager single upvote. And yes, you guessed right. :-D – Shadow The Burning Wizard Jul 23 '14 at 6:35

As can be seen in the sites lists on stackexchange.com portal, for Stack Overflow:

enter image description here

There are 7354 posted every day, in average. Each day contains 86400 seconds, so it's 0.085 questions per second or more human friendly form, a question is posted once every 11.5 seconds.

You can do the same calculation for other sites individually, but you'll have to sum your results to get the figure for the network as a whole.
