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 of this important data. As the chart 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.
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.

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 known to BloodBook.com. Those are

A Word about DNA Genealogy and Anthropology Testing - DNA research on 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,
and which are relatively unique to specific populations, are used to assess
probabilities of ancestral relatedness.
