Global Migration and Labour
Migration is a fundamental process shaping the geography of global development. The movement of people across borders drives economic growth, transforms communities, and raises complex questions about identity, rights, and governance.
Key Definition: Migration is the movement of people from one place to another, involving a permanent or semi-permanent change of residence. International migration specifically involves crossing national borders.
Push and Pull Factors
Migration decisions are shaped by a combination of push factors (conditions that drive people away from their origin) and pull factors (conditions that attract people to a destination).
Push Factors
- Economic — unemployment, low wages, lack of economic opportunity, poverty
- Political — persecution, war, conflict, political instability, authoritarian rule
- Social — discrimination (ethnic, religious, gender-based), lack of access to education or healthcare
- Environmental — natural disasters, drought, climate change, environmental degradation
- Demographic — overpopulation, pressure on resources
Pull Factors
- Economic — higher wages, better job opportunities, economic growth, demand for labour
- Political — political stability, democracy, rule of law, asylum protection
- Social — family reunification, access to education and healthcare, cultural connections
- Environmental — better climate, more resources, less environmental risk
- Demographic — ageing populations in destination countries creating labour shortages
Important Note: Migration is rarely caused by a single factor. Most migration decisions involve a complex combination of push and pull factors, along with personal circumstances and the availability of resources to move.
Lee's Migration Model
Everett Lee's model (1966) identifies four sets of factors influencing migration decisions:
The Four Components
- Factors associated with the area of origin — both positive (family, community, familiarity) and negative (unemployment, conflict) factors
- Factors associated with the area of destination — both positive (better wages, freedom) and negative (unfamiliar culture, discrimination) factors
- Intervening obstacles — physical, legal, and financial barriers between origin and destination (distance, visa requirements, cost of travel, border controls)
- Personal factors — age, gender, education, family status, personality, and perception of risk
Strengths and Limitations
Strengths:
- Recognises that both origin and destination have positive and negative attributes
- Acknowledges the role of intervening obstacles in shaping migration patterns
- Highlights the importance of personal factors and perception
Limitations:
- Oversimplifies the decision-making process — migration is not always a rational choice
- Does not adequately account for the role of social networks (chain migration)
- Treats migration as an individual decision, ignoring household strategies and structural factors
- Does not explain why some people migrate whilst others in similar circumstances do not
Types of Migration
Voluntary vs Forced Migration
| Characteristic | Voluntary Migration | Forced Migration |
|---|
| Motivation | Economic opportunity, lifestyle choice | Conflict, persecution, disaster |
| Legal status | Economic migrant, skilled worker | Refugee, asylum seeker, IDP |
| Choice | Degree of choice in destination | Limited or no choice |
| Return | May return if conditions change | Often unable to return safely |
| Example | Polish workers in the UK | Syrian refugees in Turkey |
Economic Migrants vs Refugees
The legal distinction between economic migrants and refugees is significant:
- A refugee is defined by the 1951 UN Refugee Convention as someone who has fled their country due to a well-founded fear of persecution based on race, religion, nationality, political opinion, or membership of a particular social group
- An economic migrant is someone who moves primarily to improve their economic circumstances
- An asylum seeker is someone who has applied for refugee status but has not yet received a decision
- An internally displaced person (IDP) is someone who has been forced to flee their home but remains within their country's borders
As of 2023, UNHCR estimated that there were 108.4 million forcibly displaced people worldwide, including 35.3 million refugees, 62.5 million IDPs, and 5.4 million asylum seekers.
Brain Drain and Brain Gain
Brain Drain
Brain drain occurs when highly skilled and educated people emigrate from developing to developed countries, depriving their home countries of human capital.
Examples:
- Over 70% of Haitian professionals live abroad, primarily in the USA and Canada
- Sub-Saharan Africa has lost approximately 20,000 doctors and nurses to migration since 2000
- The Philippines trains thousands of nurses annually, many of whom emigrate to the USA, UK, and Middle East
- India and China lose significant numbers of STEM graduates to Silicon Valley and other technology hubs
Impacts on Sending Countries:
- Loss of skilled workers undermines economic development and public services
- Investment in education is lost when graduates emigrate
- Can create a vicious cycle — brain drain worsens conditions, encouraging further emigration
Brain Gain
Brain gain refers to the potential benefits of skilled emigration for sending countries:
- Remittances — skilled migrants typically earn more and send larger remittances
- Diaspora networks — emigrants maintain connections with their home countries and may invest, mentor, or return with new skills
- Return migration — some migrants eventually return, bringing skills, capital, and international connections
- Incentive effect — the prospect of emigration may encourage more people to invest in education
