New Census Bureau statistics provide the latest evidence of how America is evolving in terms of race. For the first year in modern U.S. history, more white people died than were born from July 2011 to July 2012, due to an aging white population. And half the U.S. children under age five currently are minorities. Here's something else: The total minority population has grown 21 times as fast as that of whites since 1970.

All this leads experts to say the country is on track have a nonwhite majority in 30 years. Even before then, "today’s racial and ethnic minorities will no longer be dependent on older whites for their economic well-being," says population scholar William Frey of the Brookings Institution in Washington, D.C. Policy issues important to minority groups "will hold greater sway than ever before," he adds.

For now, whites still are the majority with 63% of the population – a drop from 69% in 2000 and 80% in 1980. Hispanics are the largest minority group (17%), followed by blacks (12%) and Asians (5%). At the local level, more than 11 per cent of the nation’s 3,143 counties were "majority-minority" by mid-2012. In Texas, white Americans became the minority in three counties last year. Hispanics are expected to become that state's largest ethnic group by 2020.
