To answer your question, it's O+ with 39 percent of the population having it. At 31 percent is A+, B+ and O- are both at 9 percent respectively, followed by A- at 6 percent, AB+ at 3 percent, B- at 2 percent, with AB- the rarest of the population at just 1 percent.

O+ - 39%
A+ - 31%
B+ - 9 %
O- - 9%
A- - 6%
AB+ - 3%
B- - 2%
AB- - 1%

People with an O- blood type are considered universal donors as they can donate to anyone, no matter what blood type the person receiving the transfusion has.

I think it's the o blood type/group. This means the absence of the a or b antigen on the erythrocyte or red blood cell. I believe they are referred to as the universal donor. They can be transfused into the a b ab or o recipients without causing an immunologic reaction. They are normally given in emergency situations where there is no time to do a blood group test.

They can be safely given.

The figures for blood type O seem low to me. In my text "Human Anatomy & Physiology" it list four groups within America.
Whites @ 45%
Blacks @ 49%
Asiam @ 40%
Native Americans @ 79%
It fails to list Hispanics. Could the huge influx of that population cause the percentages to fall that far?
