"The rarest blood type in the U.S. blood donor population is AB-negative, clocking in as the blood type for only 1% of the population. B-negative makes up only 2 percent of our population, followed by AB-positive at 4%. The total distribution of blood types in the U.S. is as follows:
AB-negative – 1 %
B-negative – 2 %
AB-positive – 4 %
A-negative – 6 %
O-negative – 7 %
B-positive – 11 %
A-positive – 32 %
O-positive – 40 %
