The most common blood types in the world

Each blood group has different qualities. For example, type O- are universal donors: they can donate blood to anyone. Instead, AB+ are universal recipients, so they can receive donations from any group.

For his part, according to Statesman the most common group in the world is the O+. Although when analyzing by region the results are different. In the case of the European continent, the majority of the population has A+ blood.

In contrast, only two countries on the planet of those registered in the World Population Review have a higher proportion of B+ blood groups: Pakistan and Bangladesh.

The countries with the clearest preponderance of a certain blood group are all of the O+ blood type, with 75% of the population from Ecuador, followed by 70% from Peru and 63% from Zimbabwe.
