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.

BCS preliminary facts

• 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.

BCS written analysis

Build an analytical answer

• Migration is a relatively permanent or semi-permanent movement of people across a meaningful spatial boundary.
• Push factors encourage departure, pull factors attract migrants, and intervening obstacles or opportunities filter the movement. Use rural-to-urban migration often proceeds through smaller towns before a major city. as a named application in a comparative answer.

Common misconceptions

• Migration is not the same as daily commuting.
• A refugee is not defined merely by poverty or unemployment.

Quick revision

• Migration
• Internal migration occurs within a country; international migration crosses a state boundary.
