According to the UN Department of Economic and Social Affairs, the number of Chinese people who live in America is 3.79 million as of 2013. Of this figure, more than half (2.2 million) were born in China.
Between the years 2000 and 2010, the number of Chinese people living in the United States doubled. A large reason for this is a growing middle class in China that can now afford to emigrate overseas.
Most Chinese people who move to America do so for educational or business reasons. Although economic growth in China has been relatively strong, some uncertainty has caused many Chinese people to go to the United States for better opportunities.
