Category:Huge cities with multi-tier district hierarchy

This category is an experiment and is populated by an experimental template or template functionality. Please do not remove this tag until a consensus to do so has been reached on the article/template's discussion page.

This category contains huge cities which have multiple levels of hierarchy under them. This scheme is usually reserved for only the world's largest and most important cities, those for which our coverage has exceeded the limits of what is feasible with a single layer of district articles.
