This visualisation is an experiment to analyse and map new (as at December 2013) data on mortgage lending from seven institutions, blended with two other sources: (i) modelled postcode district boundaries from the good folk at OpenStreetMap; and (ii) data from the 2011 Census on households and tenure.

I have made various assumptions about the total value of outstanding loans at postcode district level. So, my analysis comes with significant health warnings. For further information, please see my blog.
