“What blood type is the most common?”

The AB negative blood is the rarest of the eight blood types. The blood types and commonness are as follow: O+ 35%; O- 13%; A+ 30%; A- 8%; B+ 8%; B- 2%; AB+ 2%; AB- 1%. People with AB blood are Universal recipients because they have no antibodies to A, B or Rh in their blood. Thank you.

O+ is the most common with A+ a very close second.
