I noticed that there was no good map covering all countries with serious data, so I made one.
This map was made based on the combined data from Wikipedia, Worlddata.info, a study by Grasgruber et al. (2016) (for the Middle East and North Africa), Diggita (for Italian regions) and Destatis (for German states). Other anthropological studies not published online were used for Dutch, French and Spanish regions.
