Hispanic population exceeds 50 million, firmly nation's No. 2 group

The growing Hispanic population in the United States has reached a new milestone, topping 50 million, or 16.3% of the nation, officially solidifying its position as the country's second-largest group, U.S. Census Bureau officials said Thursday.

"Overall, we've learned that our nation's population has become more racially and ethnically diverse over the past 10 years," Nicholas A. Jones, chief of the bureau's racial statistics branch, told reporters.

Several trends emerged from the 2010 census, according to Robert M. Groves, director of the census bureau, and Marc J. Perry, chief of the population distribution branch.

The country is growing at a smaller rate. Growth is concentrated in metropolitan areas and in the American West and South. The fastest-growing communities are suburbs such as Lincoln, California, outside Sacramento. And standard-bearer cities such as Boston, Baltimore and Milwaukee are no longer in the top 20 for population, replaced by upstarts such as El Paso, Texas, and Charlotte, North Carolina, the officials said.

The most significant trend, however, appeared to be the nation's new count of 50.5 million Latinos, whose massive expansion accounted for more than half of the nation's overall growth of 27.3 million people, to a new overall U.S. population of 308.7 million, officials said.
