SSC Geography QUESTION #6343
Question 1
The 'gravity model of migration' predicts migration flow between two places is:
  • Directly proportional to population product and inversely proportional to distance✔️
  • Determined primarily by wage differentials
  • Based on cultural and linguistic similarities
  • Random and unpredictable
Correct Answer Explanation
The migration gravity model: Migration between places i and j increases with their populations and decreases with distance squared. Larger populations = more potential migrants; greater distance = higher costs/friction.
