The Most Widespread Blood Types, by Country

Blood is essential to the human body’s functioning. It dispenses crucial nutrients throughout the body, exchanges oxygen and carbon dioxide, and carries our immune system’s “militia” of white blood cells and antibodies to stave off infections.

But not all blood is the same. The antigens in one’s blood determine their blood type classification: There are eight common blood type groups, and with different combinations of antigens and classifications, 36 human blood type groups in total.

Using data sourced from Wikipedia, we can map the most widespread blood types across the globe.

Overall Distribution of Blood Types

Of the 7.9 billion people living in the world, spread across 195 countries and 7 continents, the most common blood type is O+, with over 39% of the world’s population falling under this classification. The rarest, meanwhile, is AB-, with only 0.40% of the population having this particular blood type.

Breaking it down to the national level, these statistics begin to change. Since different genetic factors play a part in determining an individual’s blood type, every country and region tells a different story about its people.

Regional Distribution of Blood Types

Asia

Even though O+ remains the most common blood type here, blood type B is relatively common too. Nearly 20% of China’s population has this blood type, and it is also fairly common in India and other Central Asian countries.

Comparatively, in some West Asian countries like Armenia and Azerbaijan, the population with blood type A+ outweighs any others.

Americas

The O blood type is the most common globally and is carried by nearly 70% of South Americans. It is also the most common blood type in Canada and the United States.

Here is a breakdown of the most common blood types in the U.S. by race:

Africa

O+ is a strong blood group classification among African countries. Countries like Ghana, Libya, Congo and Egypt, have more individuals with O- blood types than AB+.

Europe

The A blood group is common in Europe. Nearly 40% of Denmark, Norway, Austria, and Ukraine have this blood type.

Oceania

O+ and A+ are dominant blood types in the Oceanic countries, with only Fiji having a substantial B+ blood type population.

Middle East

More than 41% of the population displays the O+ blood group type, with Lebanon being the only country with a strong O- and A- blood type population.

The Caribbean

Nearly half of people in Caribbean countries have the blood type O+, though Jamaica has B+ as the most common blood type group.

Here is the classification of the blood types by every region in the world:

Unity in Diversity

Even though ethnicity and genetics play a vital role in determining a person’s blood type, we can see many different blood types distributed worldwide.

Blood provides an ideal opportunity for the study of human variation without cultural prejudice. It can be easily classified for many different genetically inherited blood typing systems.

Our individuality is a factor that helps determine our life, choices, and personalities. But at the end of the day, commonalities like blood are what bring us together.

Chart of tobacco use by country and sex in 2022

Charting Global Tobacco Use by Country and Sex

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

Globally, rates of tobacco use have been falling for decades. Today, it is estimated that one-in-five people around the world use tobacco products, according to data from the World Health Organization (WHO).

That’s still enough people to have a sizable impact on both global healthcare and the environment. And the prevalence of tobacco use by country, and by sex, varies widely.

This chart shows current tobacco use in selected countries around the world using WHO estimates for 2022.

Which People Smoke the Most?

Below we examine the entire dataset of global countries by 2022 tobacco use. Estimates are of people aged 15 years and older and include both smoked and smokeless tobacco (including vaping). Countries that had no data for 2022 have been omitted.

In almost every country, males use tobacco more than females. Globally, 36% of men are tobacco users compared to just 8% of women.

From a regional perspective, we can see many countries in Europe and Asia have higher rates of tobacco use. Indonesia and Myanmar specifically have some of the highest tobacco use rates in the world, with 73.6% of Indonesian men estimated to smoke or use tobacco.

In many Asian countries we also see a greater difference between male and female smokers compared to the rest of the world. In China for example, 47.3% of males are estimated to use tobacco compared to just 2.0% of females.

On the other hand, the Americas and especially Africa have a lower prevalence of tobacco use. Nigeria at 2.9% had the lowest rate of tobacco use in the world in 2022.
