An epidemiologist is someone who doesn't
know what he's talking about –
and makes you feel it’s your fault.

Why we should not study race
• Sordid history of race research • Race “science”
• Eugenics
• Difficult (impossible?) to define – biological?
cultural? political?
• Not a biological construct
• Neither scientifically nor anthropologically based

Why we should not study race
• Can’t really measure it
• May stigmatize
• May distract from more modifiable risk factors
• May implicitly encourage assimilation of minority
ethnic groups to the Western norm (Chaturvedi, 2001)

Why we should study race
• Public health: to eliminate “profound and
consequential oral health disparities within
the US population in relation to … race or
ethnicity” (Oral health in America, 2000) –
without data, disparities don’t “exist”
• Scientific understanding: race is one of the
strongest, most consistent predictors of
health status

What is race?
“1. an ethnic stock or division of mankind; in a
narrower sense, a national or tribal stock; in a still
narrower sense, a genealogic line of descent; a class
of persons of a common lineage. In genetics, races
are considered as populations having different
distributions of gene frequencies. 2. a class or breed
of animals; a group of individuals having certain
characteristics in common, owing to a common
inheritance; a subspecies. (Source: Taylor EJ. Dorland's
Illustrated Medical Dictionary. 27th ed. Philadelphia, W.S. Saunders, 1988,
quoted in LaViest, 1996)

What is race?
“Persons who are relatively homogeneous with
respect to biological inheritance. In a time of
political correctness, classifying by race is done
cautiously,1,2 although some organizations, e.g.,
the American Public Health Association, ask
members to record their racial/ethnic group on
membership forms.…” Last, John M. The dictionary of
epidemiology 3rd ed. NY, Oxford, 1995

What “races” exist?
• African-American / Black / Negro / African –
greater genetic diversity than any other “race”
• Asian – enormous diversity of language,
religion, culture, . . . (40% of world population)
• American Indian – over 550 federally
recognized tribes, languages, cultures
(OMB categories, a “social-political construct designed for collecting data on
the race and ethnicity of broad population groups in this country” [quoted
from Oppenheimer 2001])

Historical view of race
Racism as a political/social/scientific force in
Western Europe arose from: (1) nation states,
ethnic group identify; (2) subjugation of native
Americans; (3) African slave trade. Modern
racism then received a “scientific” rationale
and justification (Cooper and David, 1986)

Historical view of race
• English colonization of Ireland – “savages”,
“uncivilized”, “lazy”, “loose”
• English colonists applied same
characterizations to American natives and
asserted that their “savagery” was inborn.
• Africans were “heathens”, then biologically
inferior, the “antithesis of the English
colonists”
(Oppenheimer 2001 citing Takaki and others)

11
Historical view of race
• 19th century – “scientific” evidence of
heritability of morals, intellectual capacity,
social differences between Blacks and Whites
• Blacks have inherited immunity to malaria,
typhoid, tonsilitis, mumps, influenza but more
prone to TB
• “Mixed race” Negroes especially vulnerable
(Oppenheimer 2001)

Historical view of race
“Communicable diseases find their favorite propagating
grounds in the dirty negro sections of our cities, and in
insanitary negro homes in the country. From dirty homes, in
these disease-infested sections, negro people come into
intimate contact with white people every day that
passes.…The fact is not pleasant to contemplate, but it is
nevertheless true, that there are colored persons afflicted
with gonorrhea, syphilis, and tuberculosis employed as
servants in many of the best homes in the South. Various
disease often spread this way.”37

Current understanding of race
• “Human variation is self-evident; the existence
of definable groups, or races, is not.”
• Geographic variation in gene frequency is
mainly quantitative in nature.
• Human variation is primarily discordant.
• “Simultaneous treatment of many continuous
variables … is the only appropriate method for
studying human variation.”
(Cooper and David, 1986)

President’s Cancer Panel (1997)
• “Race as used in the United States is a social and
political construct derived from our Nation’s history. It
has no basis in science or anthropology.”
• “Biologically distinct races do not exist.”
• “Neither is there a genetic basis for racial
classification.”
• “Racism, rooted in the erroneous concept of biological
racial superiority, has powerful societal effects and
continues to influence science.”
From the letter of transmittal to the President from Harold Freeman, 1/30/1998

Race vs. ethnicity
“‘Race’ had been associated with supposed
biological variation, which to many observers
essentially meant distinct genetic differences
between groups. This notion has been discredited,
with a clear demonstration that genetic variation
between ‘racial' groups is small, and considerably
less than that between individuals from the same
supposed racial group.5,6 Racial categorization
based on these criteria are[sic] therefore inaccurate
and misleading, yet studies persist in using this
term.7” (Chaturvedi, International Journal of Epidemiology, 2001)
10/19/2007
The role of race in scientific research
16
Race vs. ethnicity
“In contrast ‘ethnicity', the increasingly preferred
term, is a complex construct of, assuredly biology,
but also culture, language, religion, and, importantly
for epidemiologists, distinct health beliefs and
health behaviours. Therefore ethnicity cannot be
treated as if it were another epidemiological
exposure, such as smoking or cholesterol levels, as
it encompasses a range of exposures, both
biological and environmental.” (Chaturvedi, International
Journal of Epidemiology, 2001)
10/19/2007

17
Race vs. ethnicity
“The [IOM] committee recommends an emphasis on
ethnic groups rather than on race in NIH’s cancer
surveillance and other population research. This
implies a conceptual shift away from the emphasis
on fundamental biological differences among ‘racial’
groups to an appreciation of the range of cultural
and behavioral attitudes, beliefs, lifestyle patterns,
diet, environmental living conditions, and other
factors that may affect cancer risk.”

Hispanic ethnicity
• A cultural group – to a great extent share
language, religion, customs, history,
geography – but also very diverse
• Hispanics include American Indians,
Europeans, Africans, and Asians, perhaps
even more than North Americans
• Whites in Latin America also subjugated
Indians and enslaved Africans

Referent group
• “White” as the referent group (not a
“racial/ethnic population”) – why?
• First “race”? – African
• Largest “race”? – Asian
• First “race” in America? – American Indians
• Who chooses?

Ethnocentricity
“Ethnocentricity is the inherent tendency to view
one’s own culture as the standard against which
others are judged.11… It will impinge on the
design, aims, and methods of studies and the
presentation and interpretation of results,
making ‘value free’ observation impossible.11”

Race/ethnicity is largely a political construct
• History – U.S. and everywhere else
• “Race science” has followed history and political
needs
• Before 1930, “Polish”, “Jewish”, “Irish”, etc. were
called “races”.
• Classification schemes are political (e.g., “one
drop rule” and contemporary) rather than scientific

Measuring race and ethnicity
• How measure: Observation? Self-report?
• How analyze multiracial category
• Different races for different contexts?
• Inconsistencies over time, between data
sources

23
“Socioeconomic status”
• Closely tied to race and ethnicity primarily for
historical reasons
• History of most ethnic groups in U.S. – start
as poor, suffer discrimination, advance,
discriminate, become “white”
• Extensive legal and extra-legal forces to
keep African Americans down
10/19/2007
The role of race in scientific research
24
Socioeconomic status
• More scientific, but hard to define, measure
• Not part of routine data systems in U.S.
• Typically oversimplified – education, income,
occupation
• Wealth disparities much greater than income
disparities
10/19/2007
The role of race in scientific research
25
Some reasons why SES hard to control for
• Grade in school ignores quality of education
• Income return on education differs
• Prices paid by minorities differ
• Family assets, expertise, information, access
• Vehicles, appliances, needs
• Public goods / community wealth and services
10/19/2007
The role of race in scientific research
26
SES not the whole story
• America is more race conscious than class
conscious (“classless society”, antiCommunist, anyone can succeed – historically
true compared to Europe, but less so for
nonwhites)
• Race and ethnicity are often more visible,
impede upward socioeconomic mobility

Diversity in the professions
• Where is it?
• How long have we been talking about it?
• How long will it take?
• What will it take?
• Scientists make policy as well as science

Racism and American apartheid
“As we enter the 21st century, institutional
racism remains an insidious and largely
unmeasured obstacle to improving and
eliminating the disparate health status of
African Americans in America.” National

Resegregation in American Schools
(Harvard University Civil Rights Project, Orfield G, Yun JT, June 1999)
• The American South is resegregating
• Latino students are more segregated than
African Americans
• African American and Latino students are
enrolled in suburban schools, but segregated
• Most racial groups attend diverse schools;
whites remain in overwhelmingly white
schools

Resegregation in American Schools
(Harvard University Civil Rights Project, Orfield G, Yun JT, June 1999)
• Spreading segregation has a strong class
component.
• Non-white schools tend to have concentrated
poverty; white schools almost always enroll high
proportions of students from the middle class.
• Title I has had great difficulty achieving gains in
schools where poverty is highly concentrated.

Resegregation in American Schools
(Harvard University Civil Rights Project, Orfield G, Yun JT, June 1999)
• Desegregation usually puts minority students
in schools which have better opportunities and
better prepared peer groups.
• Most white Americans believe that equal
educational opportunity is being provided;
national political leaders have largely ignored
the growth of segregation in the 1990s.
• Educational policy decisions (e.g., testing)
could punish students in segregated schools.

Racism and American apartheid
• In 1990, one-in-four African American males
age 20-29 years was under some form of
criminal justice supervision – in prison or jail,
on probation, or on parole.
• In 1995, the figure was 32% on any given day
