What are the features of a homogeneous society? Mention the name of any one country having such society?

Homogeneous society is a kinds of society that has similar kinds of people, especially where there are no significant ethnic differences. But these kinds of society are rare, 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.
