Hey folks, I just got the following data requests emailed to me and I figured that this list is probably best equipped to answer: · Number of editors who contribute 1 edit per month? · Is it possible/feasible to run editor retention metrics globally (versus just based on a single project? · Total number of editors on all projects over the past 16 years (not just ENWP)? · Global distribution of editors by region (or country), 2016 (the last I saw is from 2008 <https://en.wikipedia.org/wiki/File:Enwiki-map.png> )? · Average hours of spent by editors by segment (5+ edits and 100+ edits)?

Hi Aaron and Shannon, Could you clarify " Average hours of spent by editors by segment (5+ edits and 100+ edits)?" If that's referring to logged-in time, that information might be available, but keep in mind that a number of contributors do a variety of Wikimedia-related activities off-wiki, so the measure of time spent on-wiki will understate the total number of hours spent by contributors on Wikimedia-related activities. Regarding numbers of editors, keep in mind that some humans may have more than 1 account, sometimes for legitimate purposes and sometimes for illegitimate purposes. Also, getting an accurate count of "anonymous" editors is difficult. I don't mean to sound critical of the questions; I just want to emphasize that answers are likely to be incomplete.

We could use the labor-hours measurement based on activity sessions[1]. But I don't think that analytics keeps that metric yet. I've been following their history reconstruction work as that would feed directly into generating metrics like edit sessions. It's not a perfect approximation, but it's a good, conservative one. 1.

__· __Number of editors who contribute 1 edit per month? __

First column of https://stats.wikimedia.org/EN/TablesWikimediaAllProjects.htm .

...

__· Is it possible/feasible to run editor retention metrics globally (versus just based on a single project?

This depends if one just wants to (deduplicate and) sum different projects, or also consider interwiki events (such as a person stopping activity on a wiki but resuming activity on another wiki). I remember something was done a few years ago to see if Wikidata removed active editors from other projects and a few "migration" paths were identified in all directions. I can't find the chart/table now though.

...

__· __Total number of editors on all projects over the past 16 years (not just ENWP)?____

For a quick estimate I usually make a proportion https://stats.wikimedia.org/EN/TablesWikipediaEN.htm#editor_activity_levels : https://stats.wikimedia.org/EN/TablesWikimediaAllProjects.htm ~ https://stats.wikimedia.org/EN/TablesWikipediaEN.htm#editdistribution : x . If the active editors in most classes are about 1 : 2, then probably the total number of editors in all Wikipedias + all other project is more than twice the English Wikipedia's total e.g. over 10 millions (or over 2 millions if you consider the usual 10 edits threshold).

...

__· __Global distribution of editors by region (or country), 2016

· Average hours of spent by editors by segment (5+ edits and 100+

edits)? We do not keep track of session length per editor thus this data is not available. The most similar thing I can think of is session length of editing session which is quite different. That is a heavily sampled metric that is reported via eventlogging, some related data is reported here: https://edit-analysis.wmflabs.org/compare/ On Wed, Mar 22, 2017 at 5:03 PM, Federico Leva (Nemo) <nemowiki(a)gmail.com> wrote:

Note that "editing session" is not at all similar to an "edit session" from this: Geiger, R. S., & Halfaker, A. (2013, February). Using edit sessions to measure participation in Wikipedia. In *Proceedings of the 2013 conference on Computer supported cooperative work* (pp. 861-870).
