In the first comprehensive accounting of multiracial Americans since statistics were first collected about them in 2000, reporting from the 2010 census, made public in recent days, shows that the nation’s mixed-race population is growing far more quickly than many demographers had estimated, particularly in the South and parts of the Midwest. That conclusion is based on the bureau’s analysis of 42 states; the data from the remaining eight states will be released this week.
In North Carolina, the mixed-race population doubled. In Georgia, it expanded by more than 80 percent, and by nearly as much in Kentucky and Tennessee. In Indiana, Iowa and South Dakota, the multiracial population increased by about 70 percent.
“Anything over 50 percent is impressive,” said William H. Frey, a sociologist and demographer at the Brookings Institution. “The fact that even states like Mississippi were able to see a large explosion of residents identifying as both black and white tells us something that people would not have predicted 10 or 20 years ago.”
Census officials were expecting a national multiracial growth rate of about 35 percent since 2000, when seven million people — 2.4 percent of the population — chose more than one race. Officials have not yet announced a national growth rate, but it seems sure to be closer to 50 percent.
