I
have taken figures from the 2011 Census to show the four towns in
England whose populations lie closest above (and the four closest
below) that of the Western Isles:
Farnworth
(Greater Manchester) 26,939
Haverhill
(Suffolk) 27,041
Melton
Mowbray (Leicestershire) 27,158
Northfleet
(Kent) 27,628
Western
Isles 27,668
Ashington
(Northumberland) 27,670
Cramlington (Northumberland) 27,682
Stratford-Upon-Avon
(Warwickshire) 27,830
Peterlee
(Durham) 27,871
The
two Scottish urban areas with populations that are the closest above and below are:
Bathgate 25,701
Kirkintilloch 28,837
Incidentally,
the capacity of Cardiff FC's stadium is 27,815, and of Lord's Cricket
Ground in London, 28,000.
The
population of Uist, Berneray to Eriskay, (4,900) is close to that of
Bridge of Allan.
I hope this helps envisage one aspect of the 130-mile long archipelago of Eilean Siar.
