A town marked "area" takes in the villages that share its postal town. Cambridge and Peterborough are the whole council area. Bury St Edmunds, Haverhill, Newmarket, Royston and Saffron Walden sit outside the six councils, so for those we counted the homes in the town's own parish. A certificate is only made when a home is sold, let or built, so these are the homes with one, not every home. We never show a share worked out from fewer than 30 homes.
