Hispanics, the nation's largest minority group, rose 13 percent between April 2000 and July 2003 to 39.9 million, according to Census Bureau figures released Monday. That far outpaced the 3 percent increase in the American populace during the same time, to 290.8 million.
Asians were the next-fastest-growing among the large minority groups, up 12.6 percent to 11.9 million, while the black population rose nearly 4 percent to 37 million.
About 4.3 million people listed themselves as of more than one race, up 10.5 percent from 2000.
The population of Hispanics and, to a lesser extent, Asians, rose in nearly every state over the 1990s, due in large part to immigration. The latest data appear to show a continued steady flow of immigrants into America in spite of the recession and the effects of the September 11, 2001, terrorist attacks, said John Logan, a sociologist at the State University of New York at Albany.
Whites remain the single largest group at 197 million, up just 1 percent between 2000 and 2003. That number refers to those U.S. residents who are not of Hispanic ethnicity and who selected only white as their race.
"Non-Hispanic white" is what would generally be considered the majority group in the U.S. population, though they are not officially designated as such.
Over two-thirds of U.S. residents are white. Bureau projections released earlier this year showed that whites and minority groups overall would be roughly equal in size by 2050.
