Explanation:
Ravenstein's theory on migration made two main points:
- Migration is a selective process, where individuals choose to move based on specific factors such as job opportunities, economic conditions, or personal aspirations. This means that people who migrate are often different from those who choose to stay in their place of origin.
- There are certain laws or principles that govern migration patterns, such as the distance decay principle. According to this principle, the likelihood of migration decreases as the distance between the origin and destination increases. Additionally, Ravenstein proposed other principles like the gravity model, which suggests that migration is more likely between places with larger populations and shorter distances.
