Census Shows Rise in Number of Multiracial Children - NYTimes.com: Among American children, the multiracial population has increased almost 50 percent, to 4.2 million, since 2000, making it the fastest growing youth group in the country. The number of people of all ages who identified themselves as both white and black soared by 134 percent since 2000 to 1.8 million people, according to census data released Thursday.
Census 2010 is the first comprehensive accounting of how the multiracial population has changed over 10 years, since statistics were first collected about it in 2000. It has allowed demographers, for the first time, to make comparisons using the mixed-race group — a segment of society whose precise contours and nuances were largely unknown for generations. The data shows that the multiracial population is overwhelmingly young, and that, among the races, American Indians and Native Hawaiians and Pacific Islanders are the most likely to report being of more than one race. Blacks and whites are the least likely.
