Objectives. This article addresses the potential impact of the revised stan
dards for race and ethnicity on data from the 2000 census and public health
data sources, policies, and programs.
Method's. The authors examine the relationship between race/ethnicity and h
ealth in selected measures, identify the factors that influence race/ethnic
ity identification, consider past experience in race/ethnicity reporting, a
nd explore the challenges in understanding and managing the effects of new
racial/ethnic categories in various data sets.
Results. The multiple-race group seems to compose only a small percentage o
f the US population and may have little impact on data for single-race,grou
ps. Actual effects will vary according to a number of factors, including th
e size, composition, and geographic distribution of the group.
Conclusions. More research is needed to support a thorough understanding of
the reporting of multirace data and the development of techniques for anal
yzing these data. Given the importance of understanding the relationship be
tween race/ethnicity and health, the ability to produce useful, comparable,
and meaningful data is essential.
