About this data
This page tracks the decay of historical political discourse by measuring how many parliamentary speeches from 5, 10, and 15 years ago are no longer accessible online. Official records are often moved or deleted, but no one systematically tracks this loss. The data reveals patterns of institutional neglect, censorship, or simply poor archiving practices. By comparing 404 rates across different time periods, we can see how quickly public knowledge vanishes—and where accountability may be failing.
Why this isn't published anywhere else
While large parliamentary speech datasets exist, none explicitly track the decay/removal of historical records over time as a metric of institutional neglect or censorship.
Uniqueness score 0.90 — assessed against live web search results when this subject was created.
