Korean Americans are Americans of Korean ancestry. In 2015, the Korean American community constituted about 0.56% of the United States population, or about 1.82 million people, and was the fifth-largest Asian American subgroup, after Chinese Americans, Filipino Americans, Indian Americans, and Vietnamese Americans. Since 2006, the number of immigrants from North Korea to the United States has been less than 220, accounting for only 0.008352 percent of the Korean American population. Therefore, immigrants from South Korea make up more than 99 percent of the Korean American population. The U.S. is home to the largest Korean diaspora community in the world.
