Based on statistics, the rarest blood type is AB negative. According to the American Red Cross, AB negative blood type occurs in "1% of Caucasian, 0.3% of African American, 0.1% of Asian and 0.2% of Latino American" populations.
Most rare blood types by ethnicity
African American: 0.3% AB-negative, 1% B-negative, and 2% A-negative. Latin American: 0.2% AB-negative, 1% B-negative, and 2% both A-negative and AB-positive. Asian: 0.1% AB-negative, 0.4% B-negative, and 0.5% A-negative. Caucasian: 1% AB-negative, 2% B-negative, and 3% AB-positive.
Type A is common in Central and Eastern Europe. In countries such as Austria, Denmark, Norway, and Switzerland, about 45-50% of the population have this blood type, whereas about 40% of Poles and Ukrainians do so. The highest frequencies are found in small, unrelated populations.
O-negative blood type is most common in the U.S. among Caucasian adults, at around eight percent of the Caucasian population, while only around one percent of the Asian population has O-negative blood type.
Approximately 45 percent of Caucasians are type O (positive or negative), but 51 percent of African-Americans and 57 percent of Hispanics are type O. Minority and diverse populations, therefore, play a critical role in meeting the constant need for blood. Types O negative and O positive are in high demand.
O negative blood is valuable because it can be transfused to anyone, regardless of their blood type.
The most common blood types differ somewhat between Poland and Ireland. Here, 47% of people are O+, whereas in Poland 31% of the population are O+. The combined percentage of people in Ireland who are A+ and B+ is 35%; in Poland, it's 47%. There are also differences between the two countries' blood-donation procedures.
Blood group reference distribution for the German population is given as: 0: 41%; A: 43%; B: 11%; AB: 5%; Rhesus positive: 85%; Rhesus negative: 15%.
Heterogeneity between countries has become apparent and has led to the conclusion that the European Roma are composed of two different populations, characterised respectively by a high and a low frequency of blood group B [23], or defined as East and West European Roma, with the former closely related to Indian ...
Famous people with blood type O include Queen Elizabeth II, Paul Newman, Elvis Presley, Ronald Regan, John Gotti, and Gerald Ford.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
In molecular history, type A appears to be the 'oldest' blood type, in the sense that the mutations that gave rise to types O and B appear to stem from it. Geneticists call this the wild-type or ancestral allele.
What is the rarest eye color? Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
Usually, you'll have the same blood type all of your life. In rare cases, however, blood types can change. The change usually relates to unique circumstances, such as having a bone marrow transplant or getting certain types of leukemia or infections. Not all of these changes in blood type are permanent.

One of the rare blood type is the U-negative,found in Africa. In recent years, with more people of African origin living in Catalonia, the need for blood transfusions of rare types from Sub-Saharan Africa has increased.
The most common blood group for people living in the UK (44%) is the O group blood, followed by the A blood group (42%). This means these blood groups are the most commonly requested by hospitals for patients in need. The least common blood groups are B (10%) and AB (4%) blood groups.
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+.
The ranking of ABO blood groups phenotypic distribution in China is O > A > B > AB. The proportions of A, B, O and AB type in China population are 28.72%, 28.17%, 34.20%, and 8.91%, respectively.
Researchers have found that nearly 60 percent of the Hispanic population has Type O blood, which is most frequently requested by hospitals to treat a range of patients from trauma victims to premature babies.
The distribution varies worldwide. In Switzerland, blood group A is the most common (at around 45%), followed by blood group 0 (41%). The rarest blood groups are B (around 9%) and AB (around 5%).
O negative is the universal blood type. O negative blood type can only receive O negative blood. O negative donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.

As if his regular service weren't enough, Fischer learned his O-positive blood is Code 96. That means it lacks a particular combination of antigens, which makes it especially useful for specialized cases: transplants, people who have been transfused so often that they reject regular blood, and fragile babies.
Based on the primary races hypothesis, it was thought that in the three major races of man, blood groups A in Europe, B in Asian, and finally O in South America have been emerged and gradually due to the migration and mixing of the races, became the present situation.
