Talk:List of English counties by area

Wrong?
I'm worried. Firstly there's no source cited for the data; secondly it doesn't match what I've found at the National Statistics site, here. For instance, using the .xls file I calculate the area for County Durham to be 2236.85 square kilometres, as opposed to the 2226 listed in the article.

(In my calculation I added the areas for the following areas together to attain a figure for Durham: Chester-le-Street, Derwentside, Durham, Easington, Sedgefield, Teesdale, Wear Valley).

It's possible I've miscalculated but we definitely need to state (and link to, wherever possible) a source for the data in this and the related articles. An "as at" date should also be included; the data I'm looking at are dated November 2001. Waggers 12:28, 1 December 2006 (UTC)
