LSE Cities says: “Residential density measures how closely people live together. More compact cities have higher densities, while cities that sprawl and have wide open spaces between buildings have lower densities. The pattern of streets, squares and urban blocks – as well as how many people live in residential units – determines the density of a city alongside the height of individual buildings.

“More compact and less dispersed cities can promote more efficient public transport, sustainable lifestyles and economic productivity – but also can lead to congestion and overcrowding. The higher the spike on the diagrams, the higher the density. The red denotes the city administrative area and the grey is outside.”
