Measuring Globalisation: Analysts use indices to quantify interconnectedness, such as the Economic Index (trade as a percentage of GDP), the Social Index (internet penetration and international phone calls), and the Political Index (participation in international treaties).
Core-Periphery Analysis: This method examines how economic activity concentrates in 'core' regions (developed urban centers) while 'periphery' regions (underdeveloped rural areas) provide labor and raw materials. Migration is the primary mechanism that balances labor supply between these zones.
Remittance Tracking: Economists monitor the flow of money sent by migrants back to their home countries. These funds often exceed official development aid and are a critical component of the global economic system.
Demographic Profiling: Analyzing the age, gender, and skill level of migrants helps governments predict the social and economic impacts on both the source and host nations.
| Feature | Internal Migration | International Migration |
|---|---|---|
| Scale | Within national borders (e.g., rural to urban). | Across international borders. |
| Barriers | Low; usually involves cultural/linguistic similarity. | High; involves visas, borders, and language barriers. |
| Drivers | Often driven by industrialisation and land reform. | Driven by global wealth disparities and TNC labor needs. |
| Impact | Rapid urbanisation and growth of megacities. | Remittances, brain drain, and multiculturalism. |
Identify the Scale: Always distinguish whether a question is asking about global, national, or local impacts of migration. Misidentifying the scale can lead to irrelevant answers.
Use the Push-Pull Framework: When explaining why migration occurs, structure your answer by clearly categorizing factors into 'Push' (origin) and 'Pull' (destination).
Evaluate Both Sides: High-scoring answers evaluate both the benefits (e.g., labor supply, remittances) and the challenges (e.g., brain drain, social tension) for both the source and host countries.
Check for Intervening Obstacles: Don't just list reasons why people want to move; explain why they might not be able to, such as restrictive government policies or high travel costs.
The 'Homogeneous Migrant' Myth: Avoid assuming all migrants are low-skilled. Globalisation has significantly increased the migration of 'elite' high-skilled workers (e.g., tech, medicine) who are actively recruited by HDEs.
Overstating the Volume: While migration is highly visible, only about of the world's population lives outside their country of birth. Most migration is actually internal.
Ignoring Policy: Students often focus only on economic drivers and forget that government policy (e.g., points-based systems or border walls) is the ultimate filter for international migration flows.
