“In 2000, about 33 percent of the U.S. population identified themselves as members of a racial or ethnic minority group. By 2050, it is projected that these groups will account for almost half of the U.S. population.
According to the 2010 Census, the estimated number of U.S. residents of Asian descent is 17.3 million, which represents 5.6 percent of the total U.S. population. In addition, the Census Bureau has projected a 132 percentage increase between 2008 and 2050 in the population of people who identify themselves as Native Hawaiian and Other Pacific Islander. The Census Bureau also estimates that the fastest growing racial groups will continue to include the Asian/Pacific Islander (Asian American) population, with a predicted increase to 41 million by 2050.”
