Answer :
Final answer:
Retirees are the least likely to migrate according to Ravenstein's laws of human migration, as they are outside the main working-age group that migrates for economic opportunities.
Explanation:
According to Ravenstein's laws of human migration, retirees would be the group least likely to migrate. Ravenstein's laws suggest that economic factors are the main reason for migration, and that most migrants are young adults in their working years seeking job opportunities and better living conditions. Retirees, on the other hand, are usually past their prime working years and therefore less driven by such economic motivations to relocate. Additionally, migrants tend to move shorter distances and to major cities, which is less characteristic of the retirement demographic. Also, Ravenstein's law that females are more migratory than males has been disproved, as historically, large-scale migrations saw men seeking opportunities in new lands.
