Currently, population growth is fastest among minorities as a whole, says Wikipedia, and according to the Census Bureau's estimation for 2012, 50.4% of American children under the age of 1 belonged to minority groups.[19]
Hispanic and Latino Americans accounted for almost half (1.4 million) of the national population growth of 2.9 million between July 1, 2005, and July 1, 2006.[20] Immigrants and their U.S.-born descendants are expected to provide most of the U.S. population gains in the decades ahead.[21]
The approximate 2010 breakdown is White, 72.%, Af-Am, 12.6%, Asians, 4.8%, Hispanic or Latino, 16.4%.
The US Census report foresees the Hispanic or Latino population rising from 16% today to 30% by 2050, the African American percentage barely rising from 12.9% to 13.0%, and Asian Americans upping their 4.6% share to 7.8%.
The U.S. has 310 million people as of October 2010, and is projected to reach 400 million by 2039 and 439 million in 2050.[22][63][64][65] It is further projected that 82% of the increase in population from 2005 to 2050 will be due to immigrants and their children.[66]
