什么是华人？包括入籍了的华人吗？还有ABC？我google了一下：
According to the 2010 Census, the three metropolitan areas with the largest Chinese American populations were the Greater New York Combined Statistical Area at 682,265 people,[20] the San Jose-San Francisco-Oakland Combined Statistical Area at 592,865 people,[21] and the Greater Los Angeles Combined Statistical Area at about 473,323 people. New York City is home to the highest Chinese American population of any city proper (486,463), while the Los Angeles County city of Monterey Park has the highest percentage of Chinese Americans of any municipality, at 43.7% of its population, or 24,758 people.
The states with the largest estimated Chinese American populations, according to both the 2010 Census, were California (1,253,100; 3.4%), New York (577,000; 3.0%), Texas (157,000; 0.6%), New Jersey (134,500; 1.5%), Massachusetts (123,000; 1.9%), Illinois (104,200; 0.8%), Washington (94,200; 1.4%), Pennsylvania (85,000; 0.7%), Maryland (69,400; 1.2%), Virginia (59,800; 0.7%), and Ohio (51,033; 0.5%). The state of Hawaii has the highest concentration of Chinese Americans at 4.0%, or 55,000 people.
其实在美国的华人现在有很大一部分是没入籍的华人。这个数字现在应该很庞大。这个估计不在统计数字里边。
