A movement of people from one region to another within the same country

• A. Immigration
• B. Migration
• C. Emigration
• D. Relocation

Answer: (B)

The main idea here is moving within the same country. When people relocate from one region to another inside the United States, that’s domestic or internal migration. Migration is the general term for moving from one place to another, and it covers moves within a country as well as moves across international borders. In contrast, entering a country from abroad is immigration, and leaving a country to live elsewhere is emigration. Relocation is a broader, everyday term for moving but doesn’t specify crossing regions or borders. So moving from one region to another within the country fits best with migration. For example, a family moving from Ohio to Michigan represents internal migration.
