Deculturation in Shared Urban Spaces

People increasingly share the same physical places (subways, squares, celebrations) while living in distinct, non‑overlapping cultural worlds—different languages, norms, rituals and senses of belonging—which creates routine friction and weakens common civic scripts. Identifying 'deculturation' as a distinct social phenomenon focuses attention on how public space use, integration policy, and local institutions must change to preserve cooperation. — If deculturation is real and rising, it reframes immigration and urban policy from simple numbers and services to building shared rituals and civic literacy so cities remain governable and socially cohesive.
