Blood Type Distributions Around the World

It's fascinating to learn just how different types of blood are found primarily in different parts of the world. Which make sense, since blood types are inherited.

Pretty much all of South America and the western half of the US is blood type O. The majority of rest of the Americas is also blood type O. Over half of all humans have blood type O.

High density locations for blood type B are in northern India and central Asia. On the other hand, blood type A is very common for native Australians and for people from Scandinavia
