This ordering crosses district boundaries and that is the point of it. Every forecourt above is in Portsmouth as this archive labels it, and they are ranked against each other rather than against the handful that share their postcode district. Cheapest means cheapest as published in this reading, not what any of them is charging now; a forecourt that published nothing for the selected fuel carries an em dash and is out of the ordering rather than counted as zero.

Where Portsmouth is dearer and where it is cheaper

The same forecourts as above, grouped by the postcode district they sit in. This is the comparison no district page can make, because each of them holds one row of it.

What a town is here, and what it is not

A town here is the postcode districts this archive labels with its name — the commonest town among the forecourts we hold in each one. It is not a boundary anybody drew: there is no gazetteer behind this site and no coordinate is consulted to decide it, so a district on the edge of Portsmouth sits under whichever name its own forecourts filed. Two towns that share a name are kept apart by their postcode area, which is why there are four Newports on this site and one London.

The median above the fold is taken over every published price in Portsmouth, not averaged from the district medians here — that would weight a one-station district the same as a fifty-station one. Each district above has its own page, and from there its own five-mile view and its own map. Every town we hold prices for is one page up.
