I was wondering how many question and answers are posted each day at Stack Overflow?

I have gone through how many questions are opened Daily on Stackoverflow?, but I didn't get a perfect answer.

For questions:

300 / hour

7.2K / day

72K / 10 days

720K / 100 days

2.628M / year

Source


For answers:

Figure we do the math:

There are about 300 questions per hour -- 77% of which have at least one answer (based on this), so that is about 230. Half of that 230 have at least 3 answers, so that is another 230, about an eighth of the original 150 may have 4+ answers which is about another 100 - 300 answers... So 230 + 230 + 200 ish is about 660 answers , so about:

660 / hour

15.84K / day

158.4K / 10 days

1.584M / 100 days

5.782M / year


Based on real data from the past year (Sept 2012 - Sept 2013):

Source

There have been 2,170,441 Questions over the past year which calculates to about:

~247 / hour

~5.946K / day

~59.46K / 10 days

~594.6K / 100 days

~2.17M / year


There have been 3,275,577 Answers over the past year which calculates to about:

~374 / hour

~8.974K / day

~89.74K / 10 days

~897.4K / 100 days

~3.276M / year

Pshh, math .... as if that has even proven anything. P.s. you might want to check your figures at the end there ... –  Bart Oct 14 '13 at 13:54
    
@Bart hmmm where did I go wrong? Did I do maths wrong?!?! –  amanaP lanaC A nalP A naM A Oct 14 '13 at 13:56
    
10.8k / 10 days --> ??? / 100 days –  Bart Oct 14 '13 at 13:56
    
10.8K * 10 === 1.08 million... no? Unless I don't know my tens multiplication table.... CRAP!!! You are right!! –  amanaP lanaC A nalP A naM A Oct 14 '13 at 13:57
    
@Bart silly me :-P the 1st number was wrong and the last one was right ^_^ I fixed it!! YAY~~~ ^_^ –  amanaP lanaC A nalP A naM A Oct 14 '13 at 13:59
    
@amanaPlanaCAnalPAnaMA: That greats, i doesn't even guess these much answers are given.. –  Viruss mca Oct 14 '13 at 14:00

Is there a basis for "half of which have at least one answer..." and the following numbers or are they just an assumption? That would imply that the answer/question ratio is dropping, since overall the site has 11M / 5.9M answers to questions. –  Geobits Oct 14 '13 at 14:07

@Geobits I am making complete guesstimates. Given that there are 300 questions per hour. –  amanaP lanaC A nalP A naM A Oct 14 '13 at 14:08

@Geobits updated with new numbers based on 77% answered as opposed to 50% –  amanaP lanaC A nalP A naM A Oct 14 '13 at 14:17

So, TL;DR: A lot. –  Rocket Hazmat Oct 14 '13 at 14:20

@jmac Exactly and if you look at my calculations I factor that all in :-) –  amanaP lanaC A nalP A naM A Oct 14 '13 at 15:10

From August - September 13, there were 306,484 answers, which makes about 9,886 answers per day.

Does that query only count answers? Or both questions and answers? –  amanaP lanaC A nalP A naM A Oct 14 '13 at 14:46
    
@amanaPlanaCAnalPAnaMA where PostTypeId = 2 so it means only answers, I'll fix the post. –  Shadow Wizard Oct 14 '13 at 14:48
    
@amanaPlanaCAnalPAnaMA: yes, I did mean answers, my bad. –  Qantas 94 Heavy Oct 14 '13 at 14:50
    
@Qantas94Heavy I hope you don't mind that I updated your query to use in my updated answer. –  amanaP lanaC A nalP A naM A Oct 14 '13 at 15:15
    
@amanaPlanaCAnalPAnaMA: of course not. –  Qantas 94 Heavy Oct 14 '13 at 15:19

From September 13th, to October 13th.

This obviously varies greatly depending on the number of weekdays, national holidays, etc. You will have less questions/answers on a weekend than a weekday, more within US working hours than outside, etc.

This is also not including any deleted posts... –  amanaP lanaC A nalP A naM A Oct 14 '13 at 14:58
    
Correct. It does not. (I do not think that deleted posts would be as consistent since many deleted posts would be spam which I can't imagine is steady...that is a totally separate good question though). @amanaPlanaCAnalPAnaMA –  jmac Oct 14 '13 at 15:00
