Although migrants from Asia have been in parts of the contemporary United States since the 17th century, large-scale immigration did not begin until the mid-19th century. Nativist immigration laws during the 1880s–1920s excluded various Asian groups, eventually prohibiting almost all Asian immigration to the continental United States. After immigration laws were reformed during the 1940s–60s, abolishing national origins quotas, Asian immigration increased rapidly. Analyses of the 2010 census have shown that Asian Americans are the fastest-growing racial or ethnic minority in the United States.
