User:Neil Shah-Quinn (WMF)/Data portal draft


There is a great deal of publicly-available, open-licensed data about Wikimedia projects. This page is intended to help community members, developers, and researchers who are interested in analyzing raw data learn what data and infrastructure is available. If you have any questions, you might find the answer in the Frequently Asked Questions about Data.

If you wish to browse pre-computed metrics and dashboards, see statistics.

If this publicly available data isn't sufficient, you can look at the page on private data access to see what non-public data exists and how you can gain access.

If you wish to donate or document any additional data sources, you can use the Wikimedia organization on DataHub.
