Core idea

Understand the system

Migration is a relatively permanent or semi-permanent movement of people across a meaningful spatial boundary.

Why and 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.

How it works

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 terms

• push-pull
• step migration
• chain migration
• refugee
• intervening obstacle

Examples and case studies

• Rural-to-urban migration often proceeds through smaller towns before a major city.

Causes and 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 and 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

• 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
