The U.S. Census Bureau announced Asians were the nation's fastest-growing race or ethnic group in 2012 . Their population rose by 530,000, or 2.9 percent, in the preceding year, to 18.9 million, according to Census Bureau annual population estimates. More than 60 percent of this growth in the Asian population came from international migration.
By comparison, the Hispanic population grew by 2.2 percent, or more than 1.1 million, to just over 53 million in 2012. The Hispanic population growth was fueled primarily by natural increase (births minus deaths), which accounted for 76 percent of Hispanic population change. Hispanics remain our nation's second largest race or ethnic group (behind non-Hispanic whites), representing about 17 percent of the total population.
These statistics are part of a set of annual population estimates released today by race, Hispanic origin, age and sex. They examine population change for these groups nationally, as well as within all states and counties, between July 1, 2011, and July 1, 2012.
Native Hawaiians and Other Pacific Islanders (climbing 2.2 percent to about 1.4 million), American Indians and Alaska Natives (rising 1.5 percent to a little over 6.3 million), and blacks or African-Americans (increasing 1.3 percent to 44.5 million) followed Asians and Hispanics in percentage growth rates.
