On an entirely different front, just looking at urban population statistics:
I found a report
on the UK's largest urban areas from the 2001 census.
Nottingham is the 8th largest urban area in the UK. Leicester is 15th.
The top 25 urban areas account for 25 Million people - or about 43% of the country. The 25th place, incidentally, was Swansea with a size of 270,000.
It is probably fair to say that BT's *original* plan, to cover 40% of the UK by 2012, would have mainly focussed on exactly these areas (except, presumably, they can't do Kingston upon Hull).
I then wondered what BT's new plan, to cover 67% of the UK by 2015, would focus on if it only went for the top N urban areas... that needed a bit more digging.
I found this page
, which has statistics from the 2001 census on population in urban areas - which it took down to sizes of 1,500. This was for England & Wales only, so we have to ignore Scotland & NI from the figures, which may skew the results some.
This spreadsheet had 1,950 places, of size >= 1500.
I fiddled with the data in the spreadsheet, and found that it defined 46.8 Million people in these "urban areas of 1,500", from a total population of 52 Million - It was exactly 90%.
(I wonder how much the non-urban 10% correlates to the 10% that are served by market 1 exchanges, or to the "hard to reach 10%"?)
Anyway, I then applied the "two-thirds" criteria to the total E+W population, and got a value of 34.8 Million.
I then fiddled with the spreadsheet again, ordering towns by population, and found that the cutoff size for 34.8 Million people was for an urban area to be bigger than 41,000. There are 150 such places in England & Wales.
That is: The 150 largest urban areas make up 67% of England & Wales, and are sized at 41,000 or above
. In terms of "premises" that is about 17,000 premises (2.35 people per house, on average).
Just missing out would be:
- Kings Lynn
Noticeable because it was just announced, but is on the "just missing out" size:
- Aberdare, of size 36,000
Obviously my list is just population-based, and takes no account of where exchanges are, or how many people are served by an exchange. But it certainly lets you know the scale!
The other conclusion is that the "next" part
to cover - the part that presumably is to be subsidised (from 67% to 90%
) - is made up of 1,800 different locations
, with populations from 1,500 to 41,000.
