Corrections

Include enough evidence

A precise report helps distinguish a provider update from a GreenHalos processing or explanatory error.

• The GreenHalos URL.
• The data timestamp.
• The exact statement or visual issue.
• Supporting official evidence.

How changes are handled

Live source data can be superseded by the provider. GreenHalos corrects its own processing, labels and explanatory content and records material methodology changes. Material article corrections identify what changed, when it changed and the source supporting the correction.
