Summary
Migration is a relatively permanent or semi-permanent movement of people across a meaningful spatial boundary.
Core concept
Understand the system
Migration is a relatively permanent or semi-permanent movement of people across a meaningful spatial boundary.
Why / how it happens
Causes and context
Migration is a relatively permanent or semi-permanent movement of people across a meaningful spatial boundary. The governing relationship is: Push factors encourage departure, pull factors attract migrants, and intervening obstacles or opportunities filter the movement.
Mechanism / process
Push factors encourage departure, pull factors attract migrants, and intervening obstacles or opportunities filter the movement.
Key facts
- Internal migration occurs within a country; international migration crosses a state boundary.
- Ravenstein emphasized distance decay and step migration in migration patterns.
- Refugees cross borders because of a well-founded fear of persecution, unlike voluntary economic migrants.
Important terminology
- push-pull
- step migration
- chain migration
- refugee
- intervening obstacle
Named examples / case studies
- Rural-to-urban migration often proceeds through smaller towns before a major city.
Causes / components
- Key components: push-pull, step migration, chain migration.
- Push factors encourage departure, pull factors attract migrants, and intervening obstacles or opportunities filter the movement.
Effects / significance
- Ravenstein emphasized distance decay and step migration in migration patterns.
- Refugees cross borders because of a well-founded fear of persecution, unlike voluntary economic migrants.
- Application: Rural-to-urban migration often proceeds through smaller towns before a major city.
Geography connection
Rural-to-urban migration often proceeds through smaller towns before a major city. This illustrates how migration varies by location, scale or environmental context.
Bangladesh connection
Rural-to-urban movement toward Dhaka and Chattogram, overseas labour migration and displacement after disasters are major Bangladesh applications.
