Each sector's bar splits its postcodes by how many planes pass over them a day; the figure above it counts those in the busiest band the sector reaches. The list above gives the whole district's counts.

On an edge: the postcode is on the edge of a flight path, where a few metres decide whether a plane counts as overhead, and the fewest and the most within 100 m of it fall in different bands.
1 of its postcodes have a position ONS estimates, so their figures may be for a spot a few hundred metres away.
What counts as overhead
Overhead means more than halfway up the sky (48.5 degrees or more) and below 7,000 ft, the CAA's definition of an overflight (CAP 1498). A day counts as one way when 80% of its flights used that way. PO boxes and other postcodes for organisations that receive a lot of post are left out: they sit at a delivery office or a business, not at homes.
