Methodology

The non-default skin status is pulled from user_properties schema for each specific wiki. Additionally, we consider the global preference, which can override the skin setting on a local wiki. The global skin preference is pulled from the global_preferences schema in the centralauth database.

Both skin preference and global preference reflect the status as of the data collection date, which is January 28, 2026.

Editors are pulled from wmf.mediawiki_history schema. We focus on the non-bot users who have made a minimum of 1/5/60/1000 content edits on a specific wiki between 2025-01-01 and 2025-12-31.

Please note that none of the three editor groups mentioned here are identical to the active editors group that we use for measuring core product metrics. The product core metric for active editors is defined as the number of registered users who have made at least 5 content edits across all projects in the given month. (ref). For this analysis, edits are counted exclusively for the specific wiki.
