• Demographic Effects:
  

  • In-Migration (Immigration): Increases population at destination.
    

    • Example: European immigrants to the U.S. 19th–20th century.

  • Out-Migration (Emigration): Decreases population at origin.
    

    • Example: Rural youth leaving China → smaller rural population.

  • Net Migration: Difference between in- and out-migration.
    

    • Example: Snow Belt → Sunbelt retirees increase elderly population in Florida, Arizona.

• AP Tip: MC: Identify impact of migration on population; FRQ: Explain demographic changes at origin/destination.

2. Economic Effects

• Labor Supply: Migrants fill jobs in destination, may reduce labor in origin.
  

  • Example: Coastal China attracts workers from interior.

• Remittances: Migrants send money home.
  

  • Example: 2022 → $647 billion sent to developing countries; Venezuela relies heavily on remittances.

• Land & Real Estate: Out-migration may lower property values; in-migration increases demand.

• AP Tip: FRQ: Explain economic impacts of migration on both sending and receiving regions.

3. Political Effects

• Definition: Migration can alter political landscapes.

• Examples:
  

  • Europe: Muslim immigrants → debates on integration, cultural policies.

  • U.S.: Snow Belt → Sunbelt migration shifts congressional representation.

• Reapportionment: Census changes House seats due to population shifts.

• AP Tip: MC: Link migration to political changes; FRQ: Explain political implications of population shifts.

4. Social Effects

• Cultural Diffusion: Migrants bring traditions, language, religions.
  

  • Example: Cambodian & Vietnamese refugees creating ethnic neighborhoods in the U.S.

• Disease Spread: Migration can contribute to outbreaks.
  

  • Example: Cholera from Calcutta spread via human travel.

• Social Tensions: Rapid in-migration may strain resources or create cultural friction.

• AP Tip: FRQ: Discuss social effects, including integration challenges.

5. Citizenship & Cultural Belonging

  • U.S./UK: Multicultural policies with debates on assimilation.

• AP Tip: FRQ: Discuss how migration shapes cultural identity and citizenship issues.

6. Diaspora Cultures

• AP Tip: FRQ: Use examples to explain how displaced communities maintain cultural identity.
