There are racial and ethnic differences in Blood type and composition.
The ABO Blood group system was discovered in 1901 and since it is of
major importance in medicine, samples have been diligently collected
from the most remote of people groups for a century. Of no other human
characteristic is so much data available. Most populations have migrated
and mixed. Unfortunately the reliability of the Blood data for assessing
relationships between population groups is very limited. This is mostly
due to the lack of availability and interchange of this important data. As the chart
below reveals, the frequency and purity of the four main ABO Blood groups
varies in populations throughout the world. Great variation occurs in
different groups within a given country; even a small country, as one
ethnic group mixes, or not, with another. Blood type purity depends on
migration, disease, interrelational-reproductive opportunity, traditions
and customs, geography and the initial Blood type assigned.
Publishing the ethnic
differences in Blood type and the racial differences in Blood type is
not, in the present-day world, considered to be politically correct. We
compile and maintain this database through often times confidential
sources. Every Blood gathering entity in the world must gather this
information to stay in business, but almost every one of them is afraid
to publish the racial and ethnic differences in Blood type, given the
emotionally charged political climate. Discount

INFORMATION
For example, early European races
are characterized by a very low type B frequency, and a relatively high
type A frequency while the Asiatic races are characterized by a high
frequency of types A and B. The following chart does not consider Rh
factor and may vary in specific regions. It is also different for some
very particular racial or ethnic groups. We have highlighted interesting
pure anomalies.

Rare blood types can cause Blood supply problems
for unprepared Blood banks and hospitals. For example, the rare Blood
type Duffy-negative Blood, occurs much more frequently in people of
African ancestry. The relatively rarity of this rare Blood type in the
rest of the North-American population can result in a shortage of that
rare Blood type for patients of African ethnicity, in need of a Blood
transfusion. Keep in mind, if you have a rare Blood type, there may be
some risk in traveling to parts of the world where your rare Blood type
may be in short supply. Knowledge of ABO Blood type frequency can be
life saving information.

The frequency with which
Blood types are observed is determined by the frequency with which the
three alleles of the ABO gene are found in different parts of the world.
Variation in this allele frequency of the ABO gene reflects the social
tendency of populations to marry and reproduce within their national,
regional, or ethnic group. As people throughout the world intermingle to
a greater degree, the distribution of the different Blood types will
continue to become more uniform. Red cell antigens are the pheno-typical
expression of our inherited genes. One of the most common questions that
we get is about the the ethnic and racial distribution of human Blood
groups. In response, following here is our collection of basic ABO Blood
group data, sorted by people groups.
One note; we do not
consider the very small percentage of individuals who inherit unusual
combinations of "minor" antigens. Everyone carries substances on their
red Blood cells, called antigens. In addition to the well known ABO
classified groupings, and Rh factor, there are over 260 "minor" antigens
that have been identified. These antigens may appear in varying
combinations. The presence or absence of these specific "minor" antigens
single out that particular Blood type as being "rare." All Blood types
are inherited and therefore certain rare Blood combinations are more
common in specific ethnic and racial groups. We review this subject HERE. Discount

There is precise and
up-to-date data available. These racial and ethnic Blood typing and
population migration statistics are important in modern medicine for
many reasons. The overriding problem in obtaining and publishing this
information in the United States, and to a slightly lesser extent in
Western Europe, is political correctness. It is not nice to talk about
the ways that I may be different from you!
This data has some holes in
it; there are national and/or ethic groups whose statistics are not

A Word about Blood-related DNA Genealogy and Anthropological Sampling
- The relatively new science of DNA research applied to full-blooded,
indigenous populations from around the world has led to the discovery
and documentation of genetic markers that are unique to populations,
ethnicity and/or deep ancestral migration patterns. The markers having
very specific modes of inheritance, which are relatively unique to
specific populations, are used, among other things, to assess ancestral
and kinship probabilities. The following chart considers only these
full-blooded, indigenous groups.
