This page collects definitions of core metrics of the Wikimedia Product department which are tracked by the Product Analytics team. The sibling Data Dictionary page documents various data sources.
Core metrics
A set of key metrics designed to give a high-level picture of the movement's health. These are reported monthly to the Wikimedia Foundation board and on this wiki at Product Analytics, with further analysis in the quarterly metrics & insights presentations.
Content
The code that calculates these metrics can be found in the Editing-movement-metrics repository on Github.
| metric | definition | remarks |
|---|---|---|
| Total content pages | The total number of existing (non-deleted) pages in content namespaces across all wikis | Produced by summing up the net new content pages metric for provided by the Analytics Query Service over all time. |
| —Wikipedia articles | The total number of existing (non-deleted) pages in content names across all Wikipedias. | A subset of total content pages. Produced by summing up the net new content pages metric for all Wikipedias. |
| —Media files | The total number of existing (non-deleted) pages in content namespaces on Wikimedia Commons. The large majority of these are file pages, but a small number are gallery pages. | A subset of total content pages. Produced by summing up the net new content pages metric for Wikimedia Commons. |
| —Wikidata entities | The number of existing (non-deleted) Wikidata entities. | A subset of total content pages. Produced by summing up the net new content pages metric for Wikidata. |
| Net new content | The number of content pages added since the previous month, excluding deleted pages and redirects. | Produced by subtracting last month's total content pages metric from this month's. |
| —Wikipedia articles | The number of Wikipedia articles added since the previous month, excluding deleted articles and redirects. | A subset of net new content. Produced by subtracting last month's total Wikipedia articles metric from this month's. |
| —Commons files | The number of Wikimedia Commons content pages added since the previous month, excluding deleted pages and redirects. | A subset of net new content. Produced by subtracting last month's total media files metric from this month's. |
| —Wikidata entities | The number of Wikidata entities added since the previous month, excluding deleted ones and redirects. | A subset of net new content. Produced by subtracting last month's total Wikipedia entities metric from this month's. |
| Revert rate | Number of (bot and non-bot) edits which were reverted at any point before the snapshot divided by non-bot edits made during the given month. | Reverted edits are identified using the revision_is_identity_reverted field in the mediawiki_history dataset. |
| Total edits | The total number of edits made across all wikis during the given month. Edits that have been reverted or deleted are included among total edits. | Total edits has a "missing" fifth component in addition to the four components included below: the number of other bot edits. Unlike Wikistats, this metric includes edits to pages which were later deleted. |
| —Mobile edits | The number of edits tagged as having been made using the mobile website (which can be used by desktop computers) or the mobile apps. | |
| —Data edits | The number of edits to Wikidata, including bot edits. | |
| —File uploads | The number of edits, including any bot edits, which uploaded a new file on any project. | |
| —Other non-bot edits | The number of non-bot edits which were not on Wikidata and did not upload a new file, minus the number of mobile edits. | The current calculation assumes that bot edits made using the mobile site, mobile Wikidata edits, and mobile uploads are negligible. |
| —Anonymous edits | The number of edits made by anonymous users |
Editors
The code that calculates these metrics can be found in the Editing-movement-metrics repository on Github.
| metric | definition | remarks |
|---|---|---|
| Active editors | The number of registered users who made at least 5 content edits across all projects in the given month.
See meta:Research:Active editor for the full definition. |
Unlike Wikistats, this metric includes edits to pages which were later deleted. |
| —New | Active editors who registered during the given month. | |
| —Returning | Active editors who registered before the given month. | |
| New editor retention | Out of the users who registered in the month before the previous and made at least one edit in their first 30 days, the proportion who also edited during their second 30 days. This includes all edits (including edits to content, talk, and other namespaces) whether or not the edits have been reverted. | Unlike Wikistats, this metric includes edits to pages which were later deleted. |
Readers
The code that calculates these metrics can be found in the readers-movement-metrics repository on Github.
| Metric | definition | remarks |
|---|---|---|
| Content Interactions | Pageviews (all platforms) + desktop previews (see definitions below). | |
| —Pageviews | Full definition: m:R:Page view
Monthly pageviews based on calendar month Corrected for spurious IE views from some countries |
Data source: pageview_hourly
The current calculation includes user agents and automated agents We use the User Agent to define whether we assign a mobile or desktop experience; User Agents we consider to be mobile are captured in this code on Github. Most tablets are classified as mobile. |
| ——Desktop | Same limited to the desktop domains (e.g. en.wikipedia.org) | (ditto) |
| ——Mobile Web | Same limited to the mobile web domains (e.g. en.m.wikipedia.org, does not include apps) | (ditto) |
| —Desktop previews | Seen page previews, defined as previews popups that remain visible for at least one second. | Data source: virtualpageview_hourly |
| Unique Devices | Full definition: m:R:Unique Devices
Monthly unique devices for all Wikipedias (includes desktop and mobile web), based on calendar month. |
Data source: unique_devices_per_project_family_monthly |
| Android Uniques | Monthly unique users of the Android Wikipedia app. See Android core metrics | |
| Android Installs | Installs per day of the Android Wikipedia app, monthly average. See Android core metrics | |
| iOS Downloads | First-time downloads of the iOS Wikipedia app from the app store
Does not include updates or installs on an additional device using the same account. May contain Volume Purchase Program downloads and possibly some artifacts on rare occasions. |
Data source: App Annie |
Diversity
A set of contributors and readers metrics (defined above), restricted to:
- Established Market (Global North Countries) and Emerging Market (Global South Countries) : definition (based on the principles here)
- Mobile-heavy wikis: definition
Platform evolution and structured data metrics
In Platform Evolution, there are 2 metrics that are primarily impacted through Product efforts:
- Structured data used (uptake) across wikis
- non-text (e.g.Commons) content used across wikis
In New Knowledge Formats (Worldwide Readership), we are tracking Wikidata items reused on other Wikimedia projects.
These are reported monthly to the Wikimedia Foundation board and on this wiki at Product Analytics
The code that calculates these metrics can be found in the Platform-metrics repository on Github.
| Metric | definition | remarks |
|---|---|---|
| Non-text Content Used across Wikis | The number of non-text content (e.g.Commons files) that being reused on content pages across Wikimedia by the end of current month. |
|
| Structured Data Used across Wikis | The number of content pages pages across Wikimedia that reuse Wikidata by the end of current month. | Redirects are excluded from content pages. |
| Wikidata Items Reused on Other Wikimedia Projects | % of Wikidata items are reused on content pages on other Wikimedia projects by the end of current month. | Redirects are excluded from content pages. |
