Readers/Readership metrics reports
The readership metrics reports have been published by the Wikimedia Foundation's Reading team since September 2015 (initially weekly), providing a regular look at some of the most important readership metrics for Wikimedia sites. Their main purpose is to raise awareness about how these metrics are developing, call out the impact of any unusual events in the preceding week, and facilitate thinking about core metrics in general.
The reports are sent to Mobile-l and some other mailing lists, with PDF copies of past issues and other material from the reports also being available on Commons. Since December, some core metrics are being updated on a weekly basis at Wikimedia Product#Reading Audience, while the full readership metrics reports transitioned from a weekly schedule to covering longer timespans. Lastly, these metrics have also been examined with some regularity in the Metrics part of the WMF metrics and activites meetings (until late 2016, when that part of the meetings was deprecated), and in the appendix to the Reading team's quarterly review/quarterly check-in meetings (cf. examples from May 2017 or February 2017).
