Original Data Analysis
In April 2019 there was an investigation performed that looked at the number of users who regularly post and vote on Meta Stack Overflow, and how answering on Stack Overflow predicted that participation.
The results were that posting and voting on Meta is done by 200-300 users (on average), and that answering on Stack Overflow had a ...
I believe the data was just beginning to be understood differently around the time I left the company. (The timeline fits at least.) For many years the company used meta sites as a way of communicating with the most engaged users. Sometime in late 2015, I noticed a different model of meta users. Instead of seeing Meta as influencers, parts of the company ...
I'm glad you asked this... There are a lot of misconceptions surrounding how much stuff gets deleted, and who is responsible - so I'm going to provide a bit more information than what you asked for, in hopes of clearing this up.
Questions deleted during the past 365 days on Stack Overflow
659,974 questions were deleted in total
387,197 were deleted by the ...
Adzerk serves many of our ads.
There are three analytics beacons, used to gather statistics on site usage:
Google Analytics (which gives us lots of raw data we use internally)
Quantcast, which is widely used by the Internet at large to see how big we are, and
ComScore, aka the "ScoreCard Research Beacon," which many of our advertisers require to see how ...
Data can be interesting in funny ways, like being so obvious once you discover probable correlations that previously eluded you. I'm going to give a very high-level answer because the specifics are still settling and I don't want to assert ahead of people way smarter than me being certain.
We've known that engagement models (or how we derive active and ...
I ran this query to gather data on all Stack Overflow users with over 1000 reputation.
That got a total of 4,711 unique locations for 48,924 users. Of those 48,924 users, 13,138 did not list a location. Of the remaining 35,786 users, I manually inputted the country for 28,490 (almost 80%), which is the 437 most input locations, and also all locations with ...
I was about to ask a similar question. Without going into too much detail, I would slam a big Yes on this first.
Though, that's a very quick jump to a conclusion. I give this answer based on the following assumptions and my observations:
There are many spammers and random trolls around the Stack Exchange network that get banned or suspended every day. ...
It's about time for an update to this; the last one was from before some major changes to the Hot Network Questions and the world has changed a lot in the past year. This time, I'll be looking at data from April 2020 up to March 2021; see the revision history for August 2018 and August – December 2018.
Stack Exchange itself only registers (since February ...
Has there been any attempt to objectively estimate Stack Overflow users skill?
Yes, this has been done in a recently released StackApp called StackRating. Each question was seen as a "game", the responders were seen as "players" and the outcome of each game was determined by the votes. The players skill was then estimated using the Elo rating system.
In a ...
One of the main reasons we're in this mess is because SE chose to disregard one of the oldest most cherished rules in the network: we do not discuss the details of moderation actions in public. Can we please try to do better and stop trying to drag all the ugly into the light?
A user was given a short suspension by the MSE moderators. The details are ...
You don't need all these stats. Coordinated flagging of dubious posts and comments has been done and is still done by at least some of those that watch / visit the Tavern on the Meta.
That is nothing new, The Tavern has done that since its inception as far as I'm aware. It's operation is not as codified as it is in SOCVR but I've not noticed that specific ...
The data you posted on per-site metas included information on who did all that closing. I found it interesting enough to summarize here. In the table below, the sites are ordered by the percentage of closing done by diamond-less community.

Official FAQ on gender pronouns and Code of Conduct changes was one of the most downvoted questions on the whole site, sitting at -1285 5 days after posting. OP has gone from 1924 to currently 342 points:
It has since been deleted by the author. An archived version can be found here on the Wayback Machine.
An Update to our Community and an Apology ...
In my subjective perception, it just feels like a high number of users are suspended these days, but without any insights into statistics that is pure speculation.
That's always a bad starting point (without statistical data), but I can at least confirm your (subjective) observations.
Thus I am simply wondering: is the current rate of suspension still "...

I don't envision anyone over here suing you in the near future. I may sue Undo, and possibly ArtOfCode, but only if I get super-bored, and most likely for reasons unrelated to their use of SO/SE.
The lawyers would probably want me to be clear that the ToS is supposed to speak for itself, and ...
We started redirecting https://area51.stackexchange.com/users/signup, https://area51.stackexchange.com/users/login and https://stackexchange.com/users/login to https://meta.stackexchange.com/users/login
Now, not all of those will end up creating a user here; Area51 is pretty good about just logging you in and sending you back. But SE.com likes to just dump ...
Including deleted questions, the current breakdown for questions asked and closed on Dec. 9, 2013 (the period jmac used) is:
unclear what you're asking: 139
too broad: 52
primarily opinion-based: 33
Note that these numbers fluctuate as more questions are closed or reopened in the days and years ahead. Currently there are 99 ...
300 / hour
7.2K / day
72K / 10 days
720K / 100 days
2.628M / year
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+ ...
The bounty system does bring more views to bountied questions. On average, Stack Overflow questions get 1455 views. Bountied questions average 2631. It stands to reason that the more people who see a question, the better the odds it will get a quality answer.
To test that, I divided all answers into three groups:
All answers whether their question has been ...
Well... Here are a few annotated charts:
Percentage of comments flagged across all sites since March, by week
So, that's kinda boring; it varies by maybe 0.1% or so, topping out under 1.8%.
All comment flags on all sites since March, by week
All rude/unfriendly comment flags on all sites since March, by week
(if you look closely, you'll observe what ...
Make this happen. Please.
The users, super users, and moderators of each site will doubtless be interested in how their sites have performed this year.
Withholding these stats prevents users from understanding what needs to be improved in terms of question/answer quality.
Did you ever wonder how many Hot Network Questions end up being closed (because they turn out not to be suitable for the site, or to be a duplicate)? Since March 2019 that information is registered, so we can fire up the Stack Exchange Data Explorer engines to find out. SEDE doesn't include information about deleted questions, but those should be rare among ...
As hichris notes,
... this is not entirely accurate data; that there are a lot of posts deleted as spam missing from the statistics because this data is not official.
But at the same time, we see a very, very large percentage of what comes in. I'm comfortable saying that this is probably accurate enough for most use cases.
Also, in an effort to keep the ...
Let's start off with this SEDE query showing the number of times the ♦ moderators have used the ability to remove a question from the HNQ list. It has been used about 120 times in the past 6-8 weeks; more than half of it by the Mathematics mods, but to put things in perspective (thanks @BillyMailman), they only remove about 10% of the questions which ...
I'll leave the ethical discussion about how this analysis can be (ab)used to others and focus just on how you can obtain this data.
SEDE has a table PostHistory that stores in a row with PostHistoryTypeId = 10 the successful closure of a Post. (Close votes or flags that didn't lead to an actual closure are not available in SEDE). In the Text column a JSON is ...
Ok, here are the numbers for the past 120 days of migrations. Extracting the intended destination site from the logs is enough of a pain that I didn't bother, but this is broken down by would-be source site:
Migrations blocked by q-bans Source Site Name

Sure, this is possible using the built in search of every site.
For example on MSE itself:
Gives 0.496 which is 49.6% questions with accepted answer.
Worth to warn that the "answered" percentage that can be seen in the full list of sites is not related to acceptance, it means questions with at least one answer that has positive score. (88% ...
