Refers to a group of ethnically exclusionary immigrants that occupy multiple units or residences inside the same apartment building or neighborhood. The term does not necessarily indicate individuals with poor economic conditions.
For instance a large concentration of middle class, immigrant computer programmers residing in close proximity in the same apartment building would create a refugee camp.
The term is especially applicable to immigrants who refuse to interact widely with individuals outside of their own perceived ethnic group.
Such individuals may harbor racist feelings towards other ethnic groups but go unchallenged due to their recent immigrant status.
Groups of immigrants that live in close proximity to one another in the same apartment building but interact little with other residents would create a refugee camp.
