Shanghai: Noticeably lower population density

3600 people/km? vs 6000 people/km?

1.67x lower population density. Population density shows how cramped or spread out inhabitants are. Cities with high population densities can be considered overpopulated, but the extent to which this is the case depends on factors like quality of housing and infrastructure and access to resources.
