Re: [Wikimedia-l] User retention statistics?

[Yaroslav M. Blanter]

Thank you all for the replies, I need some time to process this 
information.


Cheers
Yaroslav

1. What is the average lifetime of a Wikipedia editor (for instance 
the
one with at leat 1000 contributions)? I recollect smth about two 
years, but
I am pretty sure I have never seen any research on this. How does it 
depend

on the number of contributions?

2. What are the main reasons why these editors stop editing? Is this
correct, for instance, that external reasons are much more important 
than
internal (on-wiki troubles and wiki-related harassment) reasons? The 
same

for say those above 1 edits?

Thanks in advance
Cheers
Yaroslav

PS. This story was triggered by Fastily's retirement.  He has 46000
edits on enwiki, and only about 620 editors have reached that plateau.
 Of these, 90% are still active.  So such retirements are relatively
rare.  Personally, I hope he decides to come back after taking some
time to relax and recharge.  It seems to be the case that many such
declared retirements aren't really permanent.

For enwiki, using data from last August:

28243 users have at least 1000 edits (all namespaces).

Of these, 9898 had not edited in the six months before the end of the data set.

So about 65% of the major editors are still active, at least occasionally.

The mean wiki-lifetime for the 28243 major users was 49.9 months.

For the 9898 users who were not recently active, the mean
wiki-lifetime was 35.6 months.


Further, there are 4685 users with at least 1 edits, and of these,
all but 914 were still active in the last 6 months of the data set.
So 80% of the editors at the very high end are still active (at least
occasionally).  The mean wiki-lifetime on the total group is 60.5
months, and the departed group is 42.6 months.


Incidentally, the mean account age of individuals editing article
space is now over 3 years for enwiki.  A lot of the work is being by
the relative old-timers.  By the same token though, people who have
ever made it to 1000 edits are more likely than not to still be active
today.

Re: [Wikimedia-l] User retention statistics?

[Philippe Beaudette]

Yaroslav -

You'll probably find background for some of this on the strategy wiki -
that's the community health group that you're thinking about. :-)

This is a survey in particular that might interest you:
http://strategy.wikimedia.org/wiki/Task_force/Community_Health/Former_contributors_survey

Also, Zack has some statistics from the Summer of Research, I think, on the
other questions you ask.  You might write him.
