Final answer:
Global migratory patterns are shaped by immigration, involving settling into a new country, and emigration, which means leaving one country for another. These movements are integral to understanding population changes and have vast socio-economic impacts, including labor migration and subsequent remittances.
Step-by-step explanation:
Global migratory patterns are a result of the combination of immigration, the movement of people into a country to settle, and emigration, the process by which people leave a country to settle in another. Immigration describes the action of moving into a country for the purpose of settling there permanently, while emigration is the act of leaving one's country or region with the intent to settle in another. These patterns can be attributed to various factors including economic reasons, educational opportunities, and fleeing from crises or political violence.
Migratory patterns are not only important in understanding population dynamics but also have significant socio-economic implications. For instance, labor migration is closely tied to economic need and shifting employment opportunities, and can be either permanent or circular. Circular migration often aligns with seasonal labor needs and can provide vital remittances to families in the migrants' home countries.
