About this subject
Fading Wiki Categories
This page monitors the evolution of Wikipedia's category system by identifying 'fading' categories. We specifically track the number of categories containing fewer than five articles and the overall median category size.
Data is pulled directly from Wikipedia's live category trees. Because categories are dynamic and constantly edited by the community, these figures shift as articles are reclassified or new niches emerge.
Observing these trends reveals how the collective organisation of human knowledge changes over time, highlighting where information is consolidating or where specific subjects are becoming fragmented.
