emigration
forced migration
immigration
rural - to - urban migration
voluntary migration

Explanation:

To solve this, we match each migration term with its definition:

• Emigration: Defined as leaving one's country of origin.
• Forced migration: Matches "being made to move from one place to another by someone else" as it's involuntary.
• Immigration: Is moving to another country to live there (focus on entering a new country).
• Rural - to - urban migration: Clearly corresponds to "moving from less populated areas to cities" (rural to urban).
• Voluntary migration: Matches "choosing to move from one place to another to improve conditions or to find new opportunities" as it's a choice.

Answer:

• emigration: leaving one's country of origin
• forced migration: being made to move from one place to another by someone else
• immigration: moving to another country to live there
• rural - to - urban migration: moving from less populated areas to cities
• voluntary migration: choosing to move from one place to another to improve conditions or to find new opportunities
