A little snippet of Edwin Heathcote from an old FT.
"The proportion of the United Kingdom classified as "continuous urban fabric" - ie cities is 0.1 per cent.
Another 5.3 per cent is considered "discontinuous urban fabric" (in which 50-80 per cent of the land is built on). The rest is mostly countryside. The UK might often be thought of as one of the more densely populated places to live. It is not. The densest? That would be Macau. Then Monaco, Singapore, Hong Kong, Gibraltar ... The UK comes in at number 50, eight places below Japan and just above Pakistan."
Interesting.
