How Does Lancashire Compare With Other English Counties?

Lancashire ranks 5 of 21 English counties for the share of homes in a Medium or High flood risk band. That is above the median county, at 1.8%. The comparison covers the 21 shire counties only — the 132 unitary authorities, including Bristol, York and Sheffield, have no county above them and so take no rank here.

A county figure is an aggregate of its districts, and districts differ sharply: a fenland district and an upland one in the same county can sit at opposite ends of the national ranking. Compare the towns above rather than the county total where it matters.
