I've worked with commercial suppliers of this sort of data, but don't know how much is available as freeware.
Council wards vary greatly in population, the boundary commission seeks to standardise them within individual authorities, but not nationally. Parliamentary constituencies are much more harmonised, though with anomalies especially where Islands are concerned.
There are about a 100 Postcode areas - the leading alphabetic bit. But they vary radically in population size - BT has three times the average and two of the Scottish islands are titchy - I think less than a tenth of average size.
Outward Postcodes (the first half of the Postcode) also vary widely in number of households.
Postal Sectors (the first half of the Postcode and the number at the beginning of the second half) are my favourite, the residential ones usually have around 2,000 households

Charles, I'm certainly interested. I would like to find out how may wikimedians there are in the midlands. I intend to launch an idea which is based here. At the momement I'm waiting for feedback from a number of leading wikimedians (hint yes you three), but I am unsure as to how many people are a small car ride away. So hope this idea works.
It's a tricky counting exercise, though the answer may be "100 in round terms" anyway. More to the point is how to contact people ... going by categories, userboxes and so on doesn't tell you activity level.
