Whose descendants are Americans?

A lot. But the main body must be English, that is, the descendants of Anglo-Saxons, and the rest are descendants of immigrants such as Germany (Germanic), Ireland or Scotland (Celtic/Celtic), France (France) and Jews. They are constantly married and integrated with the Anglo-Saxons and their language and culture as the main line, and it is difficult to distinguish them now.

The proportion of white speakers is over 80%, including Hispanic 1 1%. About 5% are Asians and 12% are Africans. The original indigenous Indians were just a small group.
