Certificate of Entitlement category definitions, 10-year tenure, bidding cadence, and dated quota/growth anchors used to answer car-ownership cost and rationing questions.
COE Categories, Tenure and Quota Anchors
Premiums move every bidding exercise. Quote a premium only with its exercise date; structural rules below change more slowly. Narrative interpretation lives in coe system.
Population bases
| Term | Meaning in this dataset | Do not confuse with |
|---|---|---|
| Category A/B/C/D/E | COE bidding category for the vehicle type and power band stated | ERP charges; driving-licence class |
| Quota Premium (QP) | Lowest successful bid in a closed exercise — not a forecast or long-run average | Prevailing Quota Premium for renewals |
| Total COE quota | Three-month supply across all categories for one bidding quarter | Single-category quota in one exercise |
| Vehicle population growth | Annual allowance added to the quota formula by category | Total cars on the road; ERP revenue |
