The European Union has a motto: unity in diversity. Variants of this motto make good springboards for discussion when introducing newcomers to Europe.

1. Physical diversity: The European Union is made up of many members; some are big, and others are small. Size, of course, can be measured in several ways. It’s helpful to compare geography, population, GNP or average income.

2. Linguistic diversity: Many languages are spoken in Europe. Languages vary among countries, and also within countries.

3. Religious diversity: Religious affiliation and practice vary throughout Europe. Religious freedom and religious pluralism stand out.
