Housing confers social status, and the changing norms that accompany gentrification translate to a changing social hierarchy. The process of gentrification mixes people of different socioeconomic strata, thereby congregating a variety of expectations and social norms. The change gentrification brings in class distinction also has been shown to contribute to residential polarization by income, education, household composition, and race. It conveys a social rise that brings new standards in consumption, particularly in the form of excess and superfluity, to the area that were not held by the pre-existing residents. These differing norms can lead to conflict, which potentially serves to divide changing communities. Often this comes at a larger social cost to the original residents of the gentrified area whose displacement is met with little concern from the gentry or the government. Clashes that result in increased police surveillance, for example, would more adversely affect young minorities who are also more likely to be the original residents of the area.
