Remittances are money or resources migrants send to people in their place of origin. They can pay for food, housing, schooling, health care, and small businesses. At the national level, remittances can supply foreign currency. Households may also become vulnerable to job loss abroad, transfer fees, or changing immigration rules.

The phrase brain drain describes the loss of highly trained workers from an origin country. A region that finances medical education may face shortages when clinicians move to higher-paying systems. The story can also include brain gain. Migration may encourage education, returning workers may bring skills and capital, and professional networks can connect institutions across countries. Which process dominates depends on return rates, labor demand, training capacity, and policy.

A global care chain is a cross-border series of paid and unpaid care relationships. A worker may leave children with relatives to provide child or elder care abroad. Her wages support the origin household, while her absence creates new care work for someone else. Wealthier households gain care, the migrant gains income, and the origin family manages separation and redistributed labor. Gender, class, and immigration status shape each link.

Migration data require care. A count of foreign-born residents does not reveal legal status, reason for movement, duration, or future plans. Wage differences between migrants and nonmigrants do not identify discrimination by themselves because education, credentials, language, networks, legal status, and job sorting also matter. Those factors can themselves reflect unequal institutions, so statistical control should be interpreted rather than treated as erasing the history behind a gap.

Quick review: Write the two-place account. What changes in the origin, what changes in the destination, and which family or institutional tie connects them? Migration cannot be understood from one endpoint alone.

Watch the lesson connection

Theories of Global Stratification gives you a second explanation of the ideas surrounding this lesson. As you watch, pause when the lesson concept appears and explain how the example fits.

Try the idea yourself

Write one original example, one close nonexample, and one observation that would help you tell them apart. That small exercise turns a definition into a sociological tool you can use in daily life.
