Methodology
What the two indices are made of and the rules their numbers follow, read from the API.
Data status: illustrative placeholder. Parameter version 0.7.0, engine version 0.4.0, catalogue version demo-1.0.0.
Published versions
A reading is reproducible only against all of these versions, so a saved scenario stores its request, not its figures.
| Component | Version | What it governs |
|---|---|---|
| Tourism Performance Index parameters | 0.7.0 | Pillars, weights, indicators, shocks, effect records, targets and bounds for this index |
| Culture Performance Index parameters | 0.7.0 | Pillars, weights, indicators, shocks, effect records, targets and bounds for this index |
| Engine | 0.4.0 | The arithmetic: normalisation, pathways, decomposition, target path and the what-if overlay |
| Lever catalogue | demo-1.0.0 | The levers, their instruments and the driver each instrument works through |
Index frames
Each index has its own base window, first month and horizon, so a reading is never comparable with the other index's.
| Index | Base year | Base window | First month | Latest observed | Horizon | Target end | Seasonal adjustment |
|---|---|---|---|---|---|---|---|
| Tourism Performance Index | 2024 | 2024-01 to 2024-12 | 2023-01 | 2026-09 | 2027-12 | month 96 | Applied |
| Culture Performance Index | 2025 | 2025-01 to 2025-12 | 2023-01 | 2026-09 | 2027-12 | month 96 | Applied |
Pillars and headline weights
A pillar score is the weighted sum of its indicators' normalised values, and the headline combines the pillar scores by the weights below. A gated indicator gets zero weight and the rest are re-normalised over the indicators that are not gated in the same pillar. A pillar held out of the headline is still scored but carries no headline weight.
Every Tourism Performance Index pillar is in the headline.
Held out of the Culture Performance Index headline: Heritage & Assets, Identity & Wellbeing, Reach & Exports.

Sensitivity to pillar weights
The headline at the latest observed month under the stated weights, equal weights, and each pillar left out in turn. Little movement across rows means no single weighting choice carries it.

Indicator library
Every indicator reads 100 over its base window, and each later month is its value as a ratio to the base average, seasonally adjusted where flagged. An indicator with direction -1 takes the reciprocal first, so a fall in the raw series is a rise in the index. A banded indicator reads 100 inside its band and falls the further outside it sits.
Gated in the published Tourism Performance Index spec: RPP Relative price position (real ADR vs peers).
Gated in the published Culture Performance Index spec: LCE Licensed creative enterprises and venues (gated).

Real terms
A deflated money series is divided by its index's deflator before it is normalised, so the index reads real spend. The deflator is flat at 100 until a price series is supplied, so real and nominal are the same figure today.
Tourism Performance Index: flat at 100 until a consumer price index is supplied. Deflated: RSN Real spend per visitor night, TSP Value anchor: total real visitor spend (not scored), RVP RevPAR, ADR Diagnostic: average daily rate, RPP Relative price position (real ADR vs peers).
Culture Performance Index: flat at 100 until a cultural price index is supplied. Deflated: REC Resident spend on recreation and education.
Stated and effective weights
The stated weight is the indicator's weight in its pillar times the pillar's weight; the effective weight is what the run applied. They differ wherever an indicator is gated, held at zero or in a held-out pillar, because the rest are re-normalised. Outside its band, one per cent past the nearest edge costs one point of score.

Shocks and effects
Shocks and policy effects act on drivers, and each indicator carries a sensitivity to every driver. A shock bites for its bite months and recovers linearly. An effect waits out its lag, ramps to peak, holds and decays, capped at the instrument's ceiling.
Tourism Performance Index drivers: Intl demand, Domestic demand, Access, Supply, Experience, Events, Perception.
Culture Performance Index drivers: Participation, Visitor access, Assets & venues, Talent & economy, Regulation & ecosystem, Reach.
Tourism Performance Index
| Shock | Loadings | Starts | Bite | Recovery | Central depth | In the published spec | Source |
|---|---|---|---|---|---|---|---|
| Stability | Intl demand 1.00, Perception 0.55 | 2026-04 | 3 months | 4 months | 22.0% | Active | A regional security event that cuts overseas demand and the destination's appeal. |
| Access | Access 1.00 | n/a | 0 months | 0 months | 10.0% | Switched off | Airlines withdraw seats, so fewer flights reach the destination. |

The target path
The target is a straight line from 100 at the base midpoint to the 2030 headline goal at the target end month. The goal is the headline-weighted sum of each indicator's own target index. The gap to target is the policy pathway minus that line.
Tourism Performance Index: 1 of 33 indicators carry a 2030 target. An indicator without one is carried under the spec's rule for them, grow_with_pillar, and the line arrives at month 96.
Culture Performance Index: 2 of 15 indicators carry a 2030 target. An indicator without one is carried under the spec's rule for them, grow_with_pillar, and the line arrives at month 96.
Scenario bounds
Every scenario control is bounded by the spec. A value outside a bound is refused with the engine's message, never clamped.
Tourism Performance Index
| Control | Range | Measured in |
|---|---|---|
| Indicator adjustment | -30 to 30 | per cent of the policy pathway, per indicator per month (default range pending capacity ceilings) |
| Instrument peak effect | 0 to the record's own ceiling | fraction of the driver at peak, before take-up and haircut |
| Instrument take-up | 0 to 1 | fraction of the recorded population |
| Instrument lag | 0 to 12 | months after the start month |
| Instrument ramp | 0 to 12 | months to reach peak |
| Instrument duration | 0 to 36 | months at peak |
| Instrument decay | 0 to 12 | months from peak to nothing |
| Shock start | 1 to 60 | month, to the spec's horizon |
| Shock depth | 0 to 0.5 | fraction of the driver |
| Shock bite | 0 to 12 | months at full depth |
| Shock recovery | 0 to 24 | months back to nothing |
| Pillar weight | 0.05 to 0.6 | share of the headline, before re-normalisation |
A peak-effect override is capped by the instrument's own ceiling.
