Do Europeans Have O Blood?

Yes, Europeans do have O blood—but it’s not the most common type across the continent. While O positive is the dominant blood group worldwide, Europe stands out with a different pattern. In most European countries, A positive is actually the most prevalent blood type.

This subtle shift reflects the region’s unique genetic makeup shaped by centuries of migration, isolation, and evolution. Countries like Germany, Norway, and Austria see A positive in over 35% of their populations, edging out O positive in frequency. Still, O blood remains widespread—especially in nations like Ireland and the UK, where O positive is more common than A.

Blood type distribution plays a crucial role in healthcare planning, from blood donation drives to emergency preparedness. Knowing that A positive leads in much of Europe helps medical systems keep the right balance in reserves. Yet, because O negative is the universal donor type—safe for transfusion in nearly any emergency—it’s always in high demand, regardless of regional trends.

The data, as illustrated by sources like Statista, highlights how blood types vary not just globally, but within continents. Europe may lean toward A positive, but its diversity ensures that all blood groups, including O, are well represented. This regional variation is a reminder that while humanity shares a common biology, local differences shape the details in surprising ways.
