Hispanicity, which is independent of race, is the only ethnic category, as opposed to racial category, which is officially unified by the U.S. Census Bureau. The distinction made by government agencies for those within the population of any official race category, including "Asian American", is between those who report Hispanic or Latino ethnic backgrounds and all others who do not. In the case of Asian Americans, these two groups are respectively termed Asian Hispanics and non-Hispanic Asian Americans, the former being those who say Asian ancestry from Spanish-speaking Latin America, and the latter consisting of an ethnically diverse collection of all others who are classified as Asian Americans that do not report Hispanic ethnic backgrounds.
In the 2000 US Census, 119,829 Hispanic or Latino Americans identified as being of Asian race alone.3 In 2006 the Census Bureau's American Community Survey estimated them at 154,694,4 while its Population Estimates, which are official, put them at 277,704.5 In the 2010 Census there were 598,146 Asian "Hispanic or Latinos", including those who are multiracial in origin.6
