Sino-Americans are residents of the United States who were either born in China or have (mostly Han ) Chinese ancestors (see also Chinese Abroad ). In 2000 there were approximately 2.3 million Chinese Americans, making up about 22.4 percent of all Asian Americans . In the 2010 census, the number had risen to 3.8 million. In 2016, a Chinese population of 4.9 million was counted, which corresponds to approximately 1.5% of the total US population.
In San Francisco , New York City , Los Angeles , Houston and many other American cities, a large part of the local Chinese population lived in their own neighborhoods, the so-called Chinatowns , until the middle of the 20th century .
The first wave of immigration began in 1848 during the Californian gold rush . Around 1880 there were about 130,000 Chinese living in the United States , the majority of them in California , where they mainly worked in railroad and mining . Many white workers saw them as undesirable competitors and wage pressers.
In 1882, immigration from China was banned by Congress in the Chinese Exclusion Act for an initial ten years; later this regulation was extended by the Geary Act . The Chinese were only allowed to immigrate to the United States again in 1943 (→ Magnuson Act ).
