Data quality indicates confidence in the available indicator coverage for each country.
Each indicator family may include:
dataQualityCategoricaldataQualityNumeric
The categorical level may be one of:
- Very Good
- Good
- Medium
- Poor
- Very Poor
- Not Available
Use data quality as a gating signal before score-based decisions:
- Very Good/Good: strong confidence for score interpretation
- Medium/Poor: use with caution and additional context
- Very Poor/Not Available: avoid score-only decisions
If country coverage is below threshold:

In these cases, treat the indicator as unavailable and avoid comparative ranking decisions.
