band-column-names-state-weighting

Date: 2026-09-10. Status: implemented.

Decision. PHS population-weighted bands are named simd{ed}pw; Scottish Government unweighted bands are simd{ed}uw.

Reason. The PHS guidance says the two must never be mixed in one analysis and must always be identified. A column name is the label an analyst cannot lose.

Evidence. PHS deprivation guidance v3.5, section 3.1.1 and checklist.
