how common is o positive blood

O positive blood is very common —roughly 35% to 40% of people in several large donor populations have it, making it the most common blood type in many places.

Quick Scoop

• In the UK donor data, about 35% of donors are O positive.

• In U.S.-focused sources, O positive is reported at about 37% to 40% of the population.

• Because it is so common, hospitals still need it constantly, since demand is high too.

What that means

O positive is common enough that about 1 in 3 people may have it, depending on the population being measured. It is especially important in blood donation because it can be given to any patient with a positive blood type.

TL;DR

O positive is the most common blood type in many populations , typically around a third to two-fifths of people.
