Data Quality Framework

Every data source
earns its place

Truflation indices are only as good as the data behind them. Every provider passes a rigorous two-stage evaluation before a single data point enters any index.

Stage 1 — Due Diligence

10 credibility criteria

Every provider is assessed against these ten questions using only publicly available information. A single disqualifying finding ends the evaluation immediately.

Decision rules

10 / 10Clear pass

6 – 9 / 10Clarify first

≤ 5 / 10Rejected

Legal Identity

A registered business verifiable through a public registry or official database.

Data Origin

Proprietary data collection or a valid license to redistribute.

Methodology

Publicly accessible documentation explaining how the data is produced.

Conflict of Interest

No financial positions that benefit from the provider's own published readings.

Client Credibility

Verifiable use by governments, institutions, or major organisations.

External Citation

Data cited by independent third parties in research or publications.

Leadership

An identifiable, credible team verifiably working at the company.

Business Model

Data provision is the company's core business, not a secondary offering.

Operational Longevity

Actively operating for more than 12 months with ongoing evidence.

Negative Signals

Free from regulatory actions, fraud allegations, or reputational concerns.

Stage 2 — Quality Scoring

8 dimensions of dataset quality

Each dimension is scored 0–5 and multiplied by an assigned weight. Observed Accuracy carries the highest weight — it's the most direct measure of whether the data reflects reality.

Data Delivery

Automated and API-based delivery is preferred over manual or report-only methods.

Market Coverage

Broader, more representative coverage of the target market scores higher.

Sample Size

Larger, statistically robust datasets receive higher scores.

Data Completeness

Data must be consistent and complete enough to power a live daily index.

Update Frequency

Daily or intraday updates score highest. Annual or irregular updates score lowest.

Historical Depth

Longer uninterrupted histories score higher. Less than 13 months is disqualifying.

Geographic Granularity

City or postcode-level data scores highest. Global aggregates score lowest.

Observed Accuracy

Highest weight

Correlation with credible independent sources and official benchmarks. The most direct measure of trustworthiness.

Provider tiers

The final score places each provider in a tier. Scores are reviewed annually — providers that fall to Under Review must have an active remediation plan in place.

Core Provider

Score: 80–100

Strategic, deeply integrated sources that form the backbone of Truflation indices.

Qualified Provider

Score: 60–79

Strong, reliable sources with broad coverage and consistent quality.

Conditional Provider

Score: 40–59

Supplementary sources used in specific contexts under ongoing monitoring.

Do Not Use

Score: <40

Provider does not meet minimum quality standards and must not be used in any Truflation index.

Ongoing Monitoring

Scores aren't static

Every active provider is monitored continuously. Scores are re-evaluated when material changes are detected, with a formal portfolio review conducted annually across all providers.
