Intimate segregation occurs when residents of a neighborhood coexist but have no real interaction. This is due to the residents’ differing uses of space which allow a neighborhood to remain segregated. This can be seen in gentrifying neighborhoods as the middle class moves in and businesses are beginning to cater to that class, other classes are still in the neighborhood but do not share the same amenities and space as the middle class. This leads to lack of interaction and shared spaces among the groups, even in such close quarters. This can also occur through racial classes.
