About this data

This page tracks how Wikipedia’s ‘Neutral Point of View’ (NPOV) policy is affected by citation decay. When claims rely on external sources, those links can break or domains can change, leaving evidence unsupported. We measure the 404 rate, domain change rate, and how quickly citations decay over time. The data comes from analysing NPOV-tagged claims across Wikipedia articles, highlighting how often evidence disappears and how fast this happens. Understanding this drift helps editors maintain reliable sourcing and shows where Wikipedia’s citation infrastructure needs attention.

Why this isn't published anywhere else

No existing website, dashboard, or public dataset tracks NPOV citation source drift specifically. Related efforts (e.g., link rot tools, retracted paper studies) are tangential and do not measure NPOV claim decay.

Uniqueness score 1.00 — assessed against live web search results when this subject was created.
