Politics and demographics

Methinks that our friends in the Guardian may have gone and confused individual post codes with postal sectors, which are a much more useful thing to work with - both because there are far fewer of them, 9,900 vs 1.7 million, and because there's enough information aggregated at this geographic level them to make them analytically robust. For more information on UK postal geographies see the relevant National Statistics pages.

The interesting thing about Mosaic's classifications are the way they try and subdivide areas based on income, home-ownership, number of children, occupations and so on. Not sure which [if any] of the Mosaic groups the parties are allegedly targeting [Cultural leadership, Symbols of success, Fledgling nurseries, Upscaling new owners, Affluent blue collar, Coronation St, Rustbelt resilience, Corporate chieftains, Burdened optimists, High technologists, Semi-rural seclusion, Golden empty nesters, Provincial privilege, University challengers] I fit into, but then living in a Labour safe seat I doubt if any of the parties care much about my vote.
