Aggregation & Publication Methodology

Source Aggregation

Data is aggregated prior to entry into the Meridian research environment. Property identifiers, participation markers, and operational metadata are excluded.

Geographic Smoothing

Regional groupings are predefined and do not reflect precise coordinates or property-level mapping.

Suppression Standards

Low-density distributions are suppressed to prevent identification or inference.

Reporting Lag

All publications reflect a minimum six-month lag between the reporting period and publication.

Version Control

Methodology revisions are version-controlled and require documented governance approval.
