Methodology

From source release to published chart

Each published value should remain traceable to a source, transformation, unit, period, and refresh run.

Source and transform

Source files are retained in Microsoft Fabric OneLake. Cleansed and modelled data is validated in Fabric before the read-optimised publication model is published to the website.

Website publication

The public website reads only the approved published model. Every topic should display its source, frequency, unit, covered period, and last refresh time.

Analysis notes

AI-assisted notes must be grounded in the topic dataset and source metadata. Drafts require human review before publication and should retain citations to the evidence used.
