Simple Explanation
जब higher education कुछ urban centers में concentrated हो, तो rural youth को education के लिए migrate करना पड़ सकता है। यह selective migration है क्योंकि विशेष age और skill group move करता है। मानव भूगोल educational facilities के spatial concentration और population movement के relationship को समझता है। इसलिए तीसरा विकल्प सही है। केवल urban building count या rural density इस process को नहीं समझाते। परीक्षा में service concentration और migration के बीच cause-effect संबंध पहचानना महत्वपूर्ण है। / When higher education is concentrated in a few urban centers, rural youth may have to migrate for education. This is selective migration because a particular age and skill group moves. Human geography explains the relationship between spatial concentration of educational facilities and population movement.
