Jacob and his family went to Egypt to escape famine in Cana’an. Was he a migrant or a refugee?

Refugees are defined as people fleeing their homes due to a well founded fear of persecution based on race, religion, nationality, political opinion, or membership in a social group. Anyone seeking greater economic opportunity is defined as a migrant, whom governments are not obligated to accept.

This section of the Haggadah asks whether Pharoah would have been justified in turning Jacob away? What should we do when whole populations flee war or natural disasters?
