Which blood type has the most people in the country? How many people have the same blood type as their child in 1.4 billion people? What we usually say ‘blood type’ refers to the specific antigen type on the surface of red blood cells, and human blood type is different. And, each blood type system is determined by genetic recombination, so it has medical immunological characteristics. This is the key reason why the same blood type must be infused in medicine.

Medical clinical research has found that humans have many blood types. According to the clinical tests of the world’s countries at present, in fact, there are more than 30 blood types. However, the most common are only 4 types: A-type, B-type, AB-type, and O-type. In addition, there are ‘Rh blood type system, MN and MNS blood type system’, which are more common than the four types. The other types are few and far between.

What is the most common blood type?

Among us Chinese people, A blood type accounts for about 28%, B blood type accounts for about 24%, O blood type accounts for the largest 41%, and AB blood type is the least, accounting for about 7%. In clinical medicine, there is also a relatively common blood type analysis, which is the RH blood type, mainly divided into RH positive blood and RH negative blood. The proportion of RH negative blood is very small, which is commonly known as the panda blood.

Blood type is determined by whether there are some genetically inherited antigenic substances on the surface of blood cells. At present, more than 30 blood typing systems have been discovered and recognized in humans, among which the ABO blood typing system and the RH blood typing system are more common. ABO blood type is generally divided into four types: A-type blood means that the blood cells carry an A antigen, B-type blood means that the blood cells carry a B antigen, AB-type blood means that the blood cells carry both A and B antigens, and the other is O-type blood, which means that the blood cells do not carry A or B antigens.

So, how many people in the country of 1.4 billion have the same blood type as you or the same blood type as your child?

If you want to know how many people in the country have each blood type, or how many people have the same blood type as your child, it is actually very simple. If you first go to the hospital to test your child’s blood type, then multiply the percentage of each blood type by the total population of our country, you can find out. For example:

1. The percentage of AB blood type in the total population of our country is multiplied by the total population, which is about 0.98 billion; 2. The percentage of B blood type in the total population of our country is multiplied by the total population, which is about 3.35 billion; 3. The percentage of A blood type in the total population of our country is multiplied by the total population, which is about 3.9 billion; 4. The percentage of O blood type in the total population of our country is multiplied by the total population, which is about 5.72 billion. In this way, it is clear how many people in the country have the most common blood type and how many there are in total.
