Thank you all, this has been very helpful.

 

A couple follow-up questions:

·         The geographical distribution is from 2013 correct?

·         Would someone be able to create an updated graph of editor retention on English Wikipedia up to 2016? It doesn’t have to be just ‘good-faith’ editors, I know that would be much more work. This is the one we currently have, but it would be great to have it show recent years: https://meta.wikimedia.org/wiki/Research:The_Rise_and_Decline#/media/File:Desirable_newcomer_survival_over_time.png

This will be part of a presentation from the strategy team, so if it’s possible to do by this Thursday, I would be so grateful.

Note that "editing session" is not at all similar to an "edit session" from this:

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/

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).
