The Global 'Dead-End' National Anthem Index
While most nations list an official anthem on government portals or Wikipedia, the digital files associated with them often disappear. This index measures the frequency of 'dead links'—broken audio files and missing sheet music—across global digital entries.
We calculate the ratio of broken links relative to the total number of anthems listed and monitor the average uptime of these assets, broken down by continent.
This data highlights the gap between official cultural recognition and the actual digital preservation of national symbols, revealing which regions are failing to maintain their sonic heritage.
