The golden blood type or Rh null blood group contains no Rh antigens (proteins) on the red blood cell (RBC). This is the rarest blood group in the world, with less than 50 individuals having this blood group. It was first seen in Aboriginal Australians.

AB is the least common blood type, found in about 4 percent of the U.S. population. The study found that people with AB blood were 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types.
Elsewhere in China, Beijing’s population shows somewhat different results. Just 29% of the population there is type O, while types A and AB can be found in 27% and 13% of the population respectively. Overall in Beijing, type B is the most common blood type, found in 32% of the particpants.
