The word ‘huburb’ refers to a former suburb that has developed into a hub in its own right, that is, it provides a transport hub for trains, busses or trams, it is a cultural hub with cinemas galleries or theatres, it is a shopping hub and so on.
A suburb is an area on the edge of a large town or city, typically residential in character. Whilst often attractive to the middle classes, suburbs have been criticised for being bland, sprawling and ill-defined, with insufficient density to support the social or commercial infrastructure necessary to create an effective community or urban hub.
Advocates of densification argue that the denser a city, the more sustainable it is, since dense cities use less energy per person than suburban or rural areas where people are spread over a wider distance and so travel more often and further.
