Of the 7.9 billion people living in the world, spread across 195 countries and 7 continents, the most common blood type is O+, with over 39% of the world’s population falling under this classification.
The rarest, meanwhile, is AB-, with only 0.40% of the population having this particular blood type. Breaking it down to the national level, these statistics begin to change.
Since different genetic factors play a part in determining an individual’s blood type, every country and region tells a different story about its people.
