Hi Alessandro,
Usernames are unique across Wikimedia projects now; so, it is possible to
simply union/intersect the usernames from any projects to understand the
overlap. There are, however, as you have seen a huge number of users
although most are not active in any given month. One approach I have used
[1] is to monitor the recent changes feeds for multiple projects for a time
period and look at overlap within this data, but that obviously does not
speak to longer trends. For that, I would first define a suitable metric
(e.g., one or more edits per month [2] or 5 or more edits [3], etc.) to get
a list of active editors per project.

Hello everyone,
I would like to carry out a study about how users work across different
projects in the Wikimedia ecosystem.
I can’t find any dataset containing all usernames and user ids across all
the projects, or at least those with a global account.
I’ve tried with quarry, but the query to get all the data from it is too
big and is not really a solution.
Can anybody point me to some resource I can download and process myself,
e.g. a global account user dataset, or the whole user database table that
can be queried in quarry?
Thanks,
Alessandro
