Learn More about Blood Types

How are blood types classified?

There are various types of blood that are classified based on the presence or absence of different antigens on the surface of red blood cells. A person’s blood type is determined by the presence or absence of A and B antigens, and the presence or absence of Rh antigens.

What are the most common blood types?

While there are certain rare blood types, most blood types fall into the blood groups of A, B, AB, or O, and are either positive or negative. The most common blood type is O positive, but different racial and ethnic groups have different frequencies of different blood types within their populations.

The following table summarizes the percentage of people in the United States with each of the eight most common blood types: 

Blood Type

Rh Positive

Rh Negative


A 30% 6% 36%
B 9% 2% 11%
AB 4% 1% 5%
O 39% 9% 48%
