Key Findings
- •O+ is typically the most common blood type in many countries, often ranging around the high-30s to 50%+ of the population.
- •Several Latin American and Central American countries show especially high O+ shares in this compilation (mid-50s to ~60%).
- •East Asian countries in the list tend to show comparatively lower O+ shares (often around the high-20s).
- •These differences matter for blood inventory planning because O+ demand and supply pressures vary by region.

About This Statistic
This statistic estimates, for each country, the percentage of the population whose ABO/Rh blood group is O positive (O+). Blood type distributions vary meaningfully by region and ethnicity, which affects blood supply planning, emergency preparedness, and the likelihood of compatible matches for transfusions.
Most national figures come from blood donor registries and national transfusion services (not full-population censuses). Donor data can be biased by eligibility rules and who donates, so values should be interpreted as best-available national estimates rather than exact population parameters.
