Is social division depend on the size of the country?

Social divisions of one kind or another exist in most countries. It does not matter whether the country is small or big. India is a vast country with many communities. Belgium is a small country with many communities. Even those countries such as Germany and Sweden, that were once highly HOMOGENEOUS, are undergoing rapid change with influx of people from other parts of the world. MIGRANTS bring with them their own culture and tend to form a different social community. In this sense most countries of the world are multi-cultural.
