Self-segregation or auto-segregation is the separation of a religious, ethnic, or racial group from other groups in a country by the group itself naturally. This usually results in decreased social interactions between different ethnic, racial or religious groups and can be classed as a form of social exclusion.[1]
Through self-segregation, the members of the separate group can establish their own services, and maintain their own traditions and customs. For example, some of the world's uncontacted peoples have preferred not to interact with the rest of the globally integrated human population. By remaining in a reserve and in isolation, they can preserve their cultures intact as long as they choose and the surrounding states protect them.
A modern form of self-segregation occurring in prominent Western countries for example is influenced by White demographic decline however this is not the only example and can also be found in heterogeneous ethnically and religiously diverse countries in South and Southeast Asia, for example Malaysia and India.
