simd2020v2_income_domain_rank

Scottish Government SIMD 2020v2 income domain rank, unweighted, 1 = most deprived; copied exactly as published, may end in .5

What the income domain measures (indicators in the Scottish Government's SIMD 2020v2 glossary; earlier editions' indicators differ in detail):

• Percentage of people who are income deprived (IncRate, percentage; SIMD 2020v2 glossary; reviewed (AI-assisted review, 2026-10-02, record))
• Number of people who are income deprived (IncNumDep, count; SIMD 2020v2 glossary; reviewed (AI-assisted review, 2026-10-02, record))

Table	Type	Nullable	Category	In the CSV export	SQL Server type
history table (postcode_simd_history, SPD)	rank	no	Scottish Government SIMD	yes	decimal(6,1)
main table (postcode_simd, SSPL)	rank	no	Scottish Government SIMD	yes	decimal(6,1)

Provenance (the same in both tables)

Each table runs its own copy of the table-level checks, named .history. and .main..

Where it comes from

Input	Field	Condition	Reaches the row by
data.gov.uk/SG_SIMD_2020/SG_SIMD_2020.dbf (pinned, SHA256 3eb0f27aa4aa…)	incrankv2: Income domain rank (SIMD 2020v2 glossary; reviewed (AI-assisted review, 2026-10-02, record))		DataZone2011Code = datazone

Scope: the row itself.

What was done to it: copied. The domain rank copied exactly as published; it may end in .5 where zones tie. (code: simd_ingest/core/govscot.py: read_gov_edition)

How it is checked (what each check tests; whether a build passed it is in that build's manifest.json["checks"])

• source.hash.data.gov.uk/SG_SIMD_2020/SG_SIMD_2020.dbf: the pinned file's SHA256 equals the registry's: the bytes are exactly the ones reviewed
• govscot.2020v2.columns_present: every declared shapefile column is in the file
• govscot.2020v2.key_unique: each data zone appears once in the shapefile table
• join.<table>.gov.2020v2.every_record_matched: every record found its data zone in the edition: no empty cell
• readback.<table>.attached_values: every attached value in the saved file is looked up again from the sources and equal
• govscot.2020v2.income_domain.present: the declared domain rank column is in the file
• govscot.2020v2.income_domain.complete: every zone has a domain rank
• govscot.2020v2.income_domain.half_units: every domain rank is a whole multiple of 0.5
• govscot.2020v2.income_domain.range: every domain rank is between 1 and the number of zones
• join.<table>.domain_ranks_half_units: every joined domain rank is a whole multiple of 0.5
