Data caveats

Every limitation we know about, field by field. These are the same notes shown on each layer inside the atlas, published here so you can check them before deciding whether an indicator supports the claim you want to make.

Cross-cutting method and reconciliation notes are on the methodology page.

Shown as unavailable, not zero, where no resolvable predecessor exists to inherit from.

Missing is never zero.Where a source has no figure for a district, that district renders as no-data rather than as a zero value. If a map looks patchy, that's coverage being shown honestly, not a rendering fault.
