Revise Globalisation and migration for Cambridge 9699 (8.2)

Globalisation, the process of increasing interconnectedness between societies, has fundamentally altered the scale, speed, and complexity of international migration. Sociologist David Harvey's concept of 'time-space compression' is crucial here; advancements in transport and communications technology have made the world feel smaller, reducing the friction of distance. Potential migrants are now more aware of opportunities elsewhere through global media and social networks, while cheaper air travel makes movement more feasible. This has led to what some sociologists call the 'acceleration' of migration, where movements are more frequent and diverse. Globalisation does not just facilitate migration; it creates the economic and political conditions, such as global inequalities and transnational corporations, that structure migration flows in the first place.

Contemporary migration is highly differentiated. Beyond the basic distinction between internal and international migrants, sociologists identify several key types. These include labour migrants (both high-skilled professionals and low-skilled workers), refugees fleeing conflict, and asylum seekers seeking legal protection. A significant trend is the 'feminisation of migration', where women increasingly migrate independently, often into global care chains as domestic or health workers. Furthermore, globalisation has fostered 'transnationalism', a concept explored by Steven Vertovec, where migrants maintain active connections across borders, creating hybrid identities and social networks that span multiple nations. This challenges older sociological models of assimilation, suggesting migrants can belong to more than one society simultaneously.

The classic 'push-pull' model explains migration through factors compelling people to leave (push) and attracting them to a destination (pull). In a global context, push factors like poverty, political instability, and environmental degradation are often products of global inequality. Pull factors, such as economic opportunities, political freedom, and better welfare provisions, are amplified by global media. However, sociologists like Stephen Castles critique this model as too simplistic. They argue migration is not just an individual calculation but is embedded in wider structural forces of globalisation, including the policies of nation-states, the activities of transnational corporations, and the existence of 'migration industries' (e.g., recruitment agents, traffickers) that actively shape and profit from migration flows.

Migration creates profound and often contradictory impacts. For receiving (host) societies, immigration can fill labour shortages, fuel economic growth, and lead to cultural enrichment through increased diversity. However, it can also place pressure on public services like schools and healthcare, and potentially create competition for low-skilled jobs, leading to social tensions. For sending societies, the primary benefit is often economic, through remittances sent home by migrants. These can be a vital source of national income. The major drawback is the 'brain drain'—the loss of highly skilled professionals like doctors and engineers, which can cripple a country's development prospects. Socially, it can also lead to disrupted family structures and the loss of a generation of young, dynamic citizens.
