To amend title 13, United States Code, to require certain detailed tabulations relating to Asian Americans and Pacific Islanders in the decennial censuses of population.

Requires the Secretary of Commerce to ensure that each questionnaire used in a decennial census contain at least one question relating to race or ethnic origin. Requires the question to include: (1) each group identified in the 1980 decennial census; and (2) a means to write in any group not specified.

Requires the Secretary, in carrying out any decennial census, to tabulate and make public the general population of Asian Americans and Pacific Islanders both by total and by groups.

Declares that the amendments made by this Act may not serve as a basis in the 1990 census for modifying questions relating to Hispanic origin or race.
