Where do Americans come from?

The United States is an immigrant country, and the most "pure" Americans are Indians. The following is what I picked out from Baidu's entry, hoping to help you.

The United States is the largest immigrant country in the world, and more than 1 10,000 people immigrate to the United States every year. According to the data of the 2000 U.S. Census, at present, one in every 10 people in the United States was born abroad, with 28.4 million people, accounting for 1 1% of the U.S. population. In addition, 654.38+048 million people have parents born in foreign countries, and 654.38+027 million people have only one parent.

The vast majority of Native Americans are Indians. Their ancestors came from northern China and crossed the Bering Strait from Asia to America about 40,000 years ago, or crossed the frozen continental bridge in the Strait. They share some cultural features with their Asian contemporaries, such as using fire, training dogs and some special rituals and medical methods. Archaeology and anthropology believe that the ancestors of Indians and China have the same physique. In America, there are Gan, Argentine, Iroquois, Sioux and Muskoch. About 1 10,000 years ago, another group of Asians moved to the northern part of North America, that is, Eskimos. The first white people to come to America may be a group of adventurous fishermen, Vikings, who arrived on the east coast of North America a thousand years ago. In the next 150 years, many colonists came in and settled in the coastal areas, most of them came from Britain, and some came from France, Germany, the Netherlands, Ireland and other countries.

At present, these immigrants or their descendants mainly live in California, new york, Florida, Texas, New Jersey and Illinois, accounting for 70.4% of the total. Among them, 25.9% of California residents were born abroad, and new york 19.6%. In big cities, the foreign-born population in Los Angeles accounts for 29.6%, and that in new york is as high as 36.7%. In 2007, the racial composition of the United States was: white 80. 1%, Hispanic 15. 1%, African 12.8%, Asian 4.4%, Indian and Alaska Native 1.0%, Hawaiian Native and Pacific. Among them, the total population of African-Americans, Hispanics and Asians has reached1070,000.
