How Do I Answer the Question on Race?
The individual who responds to the census decides what his or her racial
identity is. For the first time ever, people answering the census will be able
to select more than one racial category to indicate mixed racial heritage.
The groups shown in the census race question collapse into the six race
groups needed by the federal government: White, Black or African American,
American Indian and Alaska Native, Asian, and Native Hawaiian and Other
Pacific Islanders. People who mark the American Indian or Alaska Native
category are asked to provide the name of their principal or enrolled tribe.
People who say they are Other Asian, Other Pacific Islander, and/or
Some other race are asked to also write in their race.
How Do Hispanics Answer the Race Question?
People of Hispanic origin may be of any race. Hispanics can choose one or
more race categories, including White, Black or African American, American
Indian and Alaska Native, Asian, and Native Hawaiian and Other Pacific Islander.
If someone does not identify with any of the specified race groups, he or she may
mark the Some other race category and write in their race
