Hello Sociology Superstars!

Welcome to a crucial section of your A-Level studies, focusing on how and why people move across the globe and what happens when they do. This chapter, Demographic Changes – Migration and Diasporas, is vital for understanding "People and Development" because movement dramatically shapes economies, cultures, and inequalities worldwide.

Don't worry if this seems like a lot of information! We will break down complex global movements into simple concepts using clear definitions and real-world examples.

1. Understanding Why People Move: Push and Pull Explanations

The decision to migrate is rarely simple, but sociologists often categorize the underlying forces into two straightforward groups: Push Factors and Pull Factors.

1.1 Push Factors (The Reasons to LEAVE)

These are the negative forces that drive people away from their country or region of origin. Think of them as the factors pushing you out the door.

  • Economic hardship: High unemployment, low wages, lack of opportunity.
  • Conflict and instability: War, civil unrest, persecution.
  • Environmental issues: Droughts, natural disasters, famine.
  • Lack of rights: Political repression or lack of human rights/democracy.

1.2 Pull Factors (The Reasons to ARRIVE)

These are the positive attractions that draw migrants to a specific destination country. Think of them as the factors pulling you towards a new place, like a magnet.

  • Economic opportunity: High demand for labour, higher wages, better standard of living.
  • Political stability: Peace, safety, and established rule of law.
  • Social benefits: Better health care, superior education systems, welfare provisions.
  • Family ties: Existing transnational networks or family members already living there.

Quick Review: The PUSH/PULL Trick

Imagine you are being PUSHED out of a burning house (bad situation) and you are being PULLED towards a friendly neighbour offering food (good opportunity).

Key Takeaway: Migration is usually a response to a combination of terrible conditions at home (Push) and perceived opportunities elsewhere (Pull).

2. Classifying Migration: Types of Movement

2.1 Internal vs. International Migration

This is the most basic distinction based on distance and borders.

  • Internal Migration: Movement within the borders of a single country. Example: Moving from a rural village to a mega-city like Mumbai or Lagos for work (a common trend linked to urbanisation).
  • International Migration: Movement across national borders, requiring visas and border checks. Example: Moving from Mexico to the USA, or from Poland to the UK.

2.2 Specific Groups of Migrants

It is vital in Sociology to distinguish between people who move voluntarily for economic reasons and those who are forced to move for survival.

2.2.1 Refugees and Forced Migration

Forced Migration occurs when people are compelled to leave their homes due to violence, persecution, disasters, or development projects.

A Refugee is a person who has fled their home country due to a well-founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group, or political opinion, and who cannot or will not avail themselves of the protection of that country (according to the UN Convention relating to the Status of Refugees).

  • Did you know? People displaced within their own country are often called Internally Displaced Persons (IDPs), not refugees, as they haven't crossed an international border.
2.2.2 Economic Migrants and Undocumented Workers
  • Economic Migrants: Individuals who move primarily to seek employment and improve their financial status. They are making a voluntary choice based on PULL factors.
  • Undocumented Workers: These are people who have entered a country without official permission, or who have overstayed their visa and remain without legal documentation. They often work in low-paid, unregulated sectors, making them vulnerable to exploitation.

Common Mistake to Avoid: Do not confuse an economic migrant (who seeks work legally or illegally) with a refugee (who seeks asylum and protection from persecution).

3. The Role of Global Structures and Environmental Change

3.1 Borders and Visas (The Barriers)

The existence of national borders and required visas (official permissions to enter, leave, or stay in a country) acts as the primary structure controlling international migration. Developed countries use these tools to restrict who enters, often favouring highly skilled migrants and restricting low-skilled labour, even when that labour is needed.

  • The tightening of borders often increases the demand for human trafficking and makes conditions riskier for undocumented workers.

3.2 The Effect of Climate Change on Migration

Climate change is rapidly becoming a significant push factor, leading to mass forced migration.

  • Rising sea levels displace populations in low-lying island nations (e.g., in the Pacific).
  • Increased desertification and extreme weather events (droughts, floods) destroy livelihoods, especially for agricultural communities, forcing people to move internally or internationally.
  • While the term 'climate refugee' is often used, it is not yet legally recognized under international law, presenting challenges for those forced to move for environmental reasons.

Key Takeaway: Global political structures (borders) regulate movement, while environmental crises (climate change) are adding powerful new forces of displacement.

4. Outcomes of Migration: Diasporas and Transnational Networks

Migration doesn't just change the destination country; it creates enduring links between the origin and destination countries. This leads to the formation of diasporas and transnational networks.

4.1 What is a Diaspora?

A Diaspora refers to a community of people who have dispersed (scattered) from their original homeland and settled in other parts of the world, but who maintain strong cultural, emotional, or political ties to their place of origin.

  • Example: The Indian Diaspora, the African Diaspora, or the Jewish Diaspora.
  • Sociologically, diasporas maintain a shared identity, often through collective memory, cultural practices (food, religion), and language, even across generations.

4.2 Transnational Networks

These are the systems of social, economic, political, and cultural links that connect people across national borders. When migrants settle, they don't sever ties; they create bridges.

The growth and development of transnational networks allow migrants to:

  1. Send Remittances: Money sent back home to family members, which is a massive source of development aid for many poorer countries.
  2. Maintain Cultural Links: Using modern technology (like social media and video calls) to maintain family closeness and transmit culture.
  3. Influence Politics: Lobbying host governments regarding issues in their home country, or even participating in the politics of their homeland from afar.

Step-by-Step Transnationalism

1. An economic migrant moves from Country A to Country B.
2. The migrant finds a job and sends money (remittances) home.
3. The migrant regularly video calls their family and continues to speak their mother tongue.
4. This ongoing, non-stop connection forms a transnational network, proving that the migrant lives in two social worlds at once.

Key Takeaway: Migration is a fluid, continuous process that creates lasting communities (diasporas) and global bridges (transnational networks), significantly influencing development in both the sending and receiving countries.
