Asian Americans are the fastest-growing major racial or ethnic group in the United States. More than 20 million Asians live in the U.S., and almost all trace their roots to 19 origin groups from East Asia, Southeast Asia and the Indian subcontinent, according to a Pew Research Center analysis of U.S. Census Bureau data.
The Pew Research Center’s 2012 Asian-American Survey is based on telephone interviews conducted by landline and cell phone with a nationally representative sample of 3,511 Asian adults ages 18 and older living in the United States. The survey was conducted in all 50 states, including Alaska and Hawaii, and the District of Columbia. The survey was designed to include representative subsamples of the six largest Asian groups in the U.S. population: Chinese, Filipino, Indian, Japanese, Korean and Vietnamese. The survey also included Asians from other Asian subgroups.
