This chapter describes European Americans' cultural, gender, socioeconomic, family, religious, and language diversity. It discusses European American learners, and shows how teaching and learning practices can reflect knowledge of cultural differences and learning styles. The hundred-year period from 1830 to 1930 was a century of mass immigration in the history of the United States. About 32 million left Europe for the United States, contributing enormously to the nation's expansion and industrial growth. The primary reason for this massive transfer of people from the Old World to the New World was the social and economic strain on the rural systems of Europe. European Americans today live in many geographic areas of the United States. European cultures are not immune to the stereotyping that has dogged American Indian, African American, Asian American, Arab American, and Hispanic cultures. European Americans comprise numerous subcultures that vary by country and language, economic status, generation in United States, religious affiliation, and a host of other factors.
