Current Population Survey (CPS) A joint effort between the Bureau of Labor Statistics and the Census Bureau

Footnotes:

1/  The 2003 CPS asked respondents to choose one or more races.  White Alone refers to people
    who reported White and did not report any other race category.  The use of this single-race
    population does not imply that it is the preferred method of presenting or analyzing data.
    The Census Bureau uses a variety of approaches.  Information on people who reported more
    than one race, such as "White and American Indian and Alaska Native" or "Asian and Black
    or African American," is available from Census 2000 through American Factfinder.  About
    2.6 percent of people reported more than one race in 2000.  

2/  Black alone refers to people who reported Black and did not report any other race category.

3/  Asian alone refers to people who reported Asian and did not report any other race category.
