About this data

This page measures the geographic diversity of public domain image sources. We track the number of unique geographic origins, the top 10 most frequent origins, and the Herfindahl-Hirschman Index of geographic concentration. The data reveals biases in digitization efforts and global cultural representation in image archives. The numbers come from a comprehensive analysis of public domain image collections. Understanding geographic diversity in image sources is important for promoting inclusivity and representation in digital media.

Why this isn't published anywhere else

No live dashboard, recurring report, or public dataset regularly publishing statistics on the geographic diversity of public domain image sources was found; only general category pages and project descriptions exist.

Uniqueness score 0.90 — assessed against live web search results when this subject was created.
