How many Americans are immigrants? Mainly from those countries ..?

Originally, I didn't want to answer, but the answer upstairs was so funny that there was no level at all. Haha, the original United States (13 state) was colonized by Britain-the white and red stripes on the American flag refer to the original 13 state. Later, American officials and landlords were dissatisfied with the British queen system, and Washington led them to launch the War of Independence. Later, a war broke out between the master's rights and the slaves. After independence, the United States began to buy land on a large scale, buying "Iceland" Alaska from the Russian czar, "New Mexico" from the Mexicans, and Louisiana from the French, from the Mississippi River to the Rocky Mountains, to Canada in the north and to the Gulf of Mexico in the south. In these places, it can be said that the Americas is an international competition. Black people, white people, colored people ~ ~ Canada mentioned upstairs is so funny. Canada is a colony of France and Britain. Where are the Canadians? ! ! ! The population of single race in the United States is 275 million, accounting for 97.6%; 6.8 million hybrids, accounting for 2.4%. In a single race, the white population is 2 1 1 billion, accounting for 76.7% of the total population; 34 million blacks, accounting for12.3%; Asians 1024 million, accounting for 3.6%. One race in the United States consists of races from 68 different countries. There are only 465,438+million so-called American Indians and Alaska natives and their descendants, accounting for only 1.5% of the total population in China, and most of them are immigrants from other races and their descendants abroad. From the discovery of the new continent at the end of 15, Spain, the Netherlands, France, Britain and other countries began to immigrate to North America, which opened the door for American immigrants. By 1773, Britain had established 13 colonies. According to statistics, from 1820 to 183 in 2002, there were 68.22 million foreign residents living in the United States, including 38.82 million from Europe, 9.42 million from Asia, 6.5438+0895 million from America, 790,000 from Africa and 240,000 from Oceania. Among Asian countries, the country that immigrated to the United States the most was the Philippines (654.38+6300), followed by China (654.38+4400) and India (950,000).
