United States

After 1960 easy air travel and political and economic instability stimulated a significant migration from the Caribbean, Central America, and South America. The arrivals from Latin America in earlier years were often political refugees, more recently they usually have been economic refugees. Constituting about one-fourth of the Hispanic diaspora, this group comprises largely Central Americans, Colombians, and Dominicans, the last of whom have acted as a bridge between the black and Latino communities. Of Central American groups, three had population increases of more than 100 percent between 2000 and 2010. Hondurans (191 percent), Guatemalans (180 percent), and Salvadorans (152 percent). Latinos have come together for better health, housing, and municipal services, for bilingual school programs, and for improved educational and economic opportunities.

Asian Americans

Asian Americans as a group have confounded earlier expectations that they would form an indigestible mass in American society. The Chinese, earliest to arrive (in large numbers from the mid-19th century, principally as labourers, notably on the transcontinental railroad), and the Japanese were long victims of racial discrimination. In 1924 the law barred further entries; those already in the United States had been ineligible for citizenship since the previous year. In 1942 thousands of Japanese, many born in the United States and therefore American citizens, were interned in relocation camps because their loyalty was suspect after the United States engaged Japan in World War II. Subsequently, anti-Asian prejudice largely dissolved, and Chinese and Japanese, along with others such as the Vietnamese and Taiwanese, have adjusted and advanced. Among generally more recent arrivals, many Koreans, Filipinos, and Asian Indians have quickly enjoyed economic success. Though enumerated separately by the U.S. census, Pacific Islanders, such as native Hawaiians, constitute a small minority but contribute to making Hawaii and California the states with the largest percentages of Asian Americans.

Middle Easterners

Among the trends of Arab immigration in the 20th century were the arrival of Lebanese Christians in the first half of the century and Palestinian Muslims in the second half. Initially Arabs inhabited the East Coast, but by the end of the century there was a large settlement of Arabs in the greater Detroit area. Armenians, also from southwest Asia, arrived in large numbers in the early 20th century, eventually congregating largely in California, where, later in the century, Iranians were also concentrated. Some recent arrivals from the Middle East maintain national customs such as traditional dress.

Native Americans

Native Americans form an ethnic group only in a very general sense. In the East, centuries of coexistence with whites has led to some degree of intermarriage and assimilation and to various patterns of stable adjustment. In the West the hasty expansion of agricultural settlement crowded the Native Americans into reservations, where federal policy has vacillated between efforts at assimilation and the desire to preserve tribal cultural identity, with unhappy consequences. The Native American population has risen from its low point of 235,000 in 1900 to 2.5 million at the turn of the 21st century.

The reservations are often enclaves of deep poverty and social distress, although the many casinos operated on their land have created great wealth in some instances. The physical and social isolation of the reservation prompted many Native Americans to migrate to large cities, but, by the end of the 20th century, a modest repopulation occurred in rural counties of the Great Plains. In census numerations Native Americans are categorized with Alaskan natives, notably Aleuts and Eskimos. In the latter half of the 20th century, intertribal organizations were founded to give Native Americans a unified, national presence.
