About this subject

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.
