Quick: What's the fastest-growing...

...ethnic group in America? Latinos? From the U.S. Census Bureau (my emphasis):

In 2012, the Hispanic population in the United States grew by 2.2 percent, or more than 1.1 million, to just over 53 million.

But Asians were actually the country'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.
