Nicholas Jones of the US Census Bureau has just released a report on the multiracial respondents of the 2000 Census, We the People of More Than One Race in the United States.

This report provides a portrait of the Two or More Races population in the United States and discusses the twelve largest race combinations within this population at the national level. It is part of the Census 2000 Special Reports series that presents several demographic, social, and economic characteristics collected from Census 2000. Census 2000 data showed that, of the 281.4 million people in the United States, 7.3 million or 2.6 percent reported more than one race.
