One of my readers asked me to create a map showing the “density” of metal bands in European countries—and so I did. The following map shows the number of entries (which represent both active and inactive metal bands) in Encyclopaedia Metallum, divided by the country’s population in millions. For comparison: There are 72 metal bands per 1 million people in the United States.

If you are interested, I have also created the corresponding map for South America.
