Diversity in medical training data is important, through it is much more complex than getting "US, Europe, Asia and Latin America". A EU citizen in the south will have complete different set of environment to a citizen of the far north. Using climate zone classification, EU has both Temperate (mesothermal) climate and on the opposite end Polar and alpine (montane) climates. One place where the sun never goes up for part of the year, and an other where people go to beaches for vacations in the sun. Medicine that involve D-vitamin, sleep, cancer risks and a lot more is greatly effected by the latitude, which is part of the combination that is genes and environment. In the end you need a multidimensional matrix with everything from environment to genes, such as ethnic groups, gender, climate, culture and so on. If you are doing something which is similar to scientific studies then there is also an error margin in the data collection, such as in ancestry, and the error rate differ from country to country. Treating EU as a single group is plain terrible from a representation perspective. https://upload.wikimedia.org/wikipedia/commons/d/d5/K%C3%B6ppen-Geiger_Climate_Classification_Map.png https://upload.wikimedia.org/wikipedia/commons/d/d5/K%C3%B6p...
