Official-source comparison

Two facts. Kept distinct.

The Great Britain quarterly first-registration fact and Australia census-date registered-stock fact have different statistical subjects and different time grains, so they remain separate originals.

The records use identical visual weight while retaining their own definition, subject, period, coverage, source and verification state.

Why these facts stay separate

Australia reports registered vehicle stock on the census date, not sales or new registrations; Great Britain reports first registrations during a calendar quarter. These facts are not directly comparable.

Metric definitions differA stock-at-census measure and first-registration events describe different facts.
Statistical subjects differThese facts measure different vehicle populations or subjects and cannot be treated as observations of the same thing.
Time grains differThese facts use different reporting periods or census dates, so they cannot produce a like-for-like result.
Coverage scopes differThe sources cover different geographies, vehicles, or registration scopes and cannot be combined directly.
No approved derived computationThe original facts are authorized for display, but no calculated result is authorized for this pair.
No approved comparison ruleThe versioned policy has not explicitly approved this market-and-metric set, so the system denies it by default.

No derived result is available for these definitions.

The two original records remain readable. A calculated result is omitted because the server has not authorized these definitions as equivalent.
