Sources and method
Every figure in the explorer comes from the public datasets below.
The importers in scripts/import.php fetch each dataset from its publisher and store it unchanged, or as
a percentage calculated from the published counts. Constituency figures are calculated from the neighbourhood counts
(for example total fuel-poor households over total households), not averaged. Ranks are worked out in the database:
1 is the most concerning neighbourhood for that measure. Nothing is estimated by AI.
All figures are for neighbourhoods (LSOAs, about 1,500 people each). They describe the area, not any one household in it.
