What countries are European Americans originally from?

European Americans primarily originate from countries in Europe, including but not limited to England, Germany, Ireland, Italy, France, and the Scandinavian nations (Norway, Sweden, Denmark). Immigration patterns over centuries have brought diverse populations from these countries to the United States, contributing to the cultural fabric of European American identity. Additionally, many Eastern European nations, such as Poland and Russia, have also played a significant role in the ancestry of European Americans.
