Coptic Americans are American citizens of Coptic descent or persons of Coptic descent residing in the United States of America. According to the American Coptic Association, there are approximately 450,000 Copts in the United States since many ethnic Copts listed themselves in the 2011 U.S. Census mistakenly as either Egyptians, Sudanese, Libyans or Americans and by this way reducing the ethnic Coptic population in the United States to not be even included within the 2011 U.S. Census. Estimates for the number of ethnic Copts in the US range from 700,000 to more than 1 million.
