The urban landscape accounts for 10.6% of England, 1.9% of Scotland, 3.6% of Northern Ireland and 4.1% of Wales.

Put another way, that means almost 93% of the UK is not urban. But even that isn't the end of the story because urban is not the same as built on.

In urban England, for example, the researchers found that just over half the land (54%) in our towns and cities is greenspace - parks, allotments, sports pitches and so on.

Furthermore, domestic gardens account for another 18% of urban land use; rivers, canals, lakes and reservoirs an additional 6.6%.

Their conclusion?

In England, "78.6% of urban areas is designated as natural rather than built". Since urban only covers a tenth of the country, this means that the proportion of England's landscape which is built on is 2.27%.

Yes. According to the most detailed analysis ever conducted, almost 98% of England is, in their word, natural.

Elsewhere in the UK, the figure rises to more than 99%. It is clear that only a small fraction of Britain has been concreted over.
