Methodology

Where the figures come from

All figures come from Statistics Norway's StatBank through its open API. SSB's data is licensed CC BY 4.0. Every chart shows the table number, links to the table and shows when SSB last updated it.

The site never fetches figures from SSB while you read a page. It shows its own copies.

From SSB to the page

• The figures are fetched on a fixed schedule and stored unchanged, together with the query we used and the time SSB updated the table. Each update gives a new copy, and the old ones are kept.
• We fetch every figure in Norwegian and in English and accept the copy only if the figures are the same.
• An automatic check fetches the figures again and compares them with the copies. If they differ, an issue is opened and we look into it.

What we calculate

SSB's own figures are never changed. When a chart shows something SSB has not published (a share, a change, a ranking, a division into classes), the calculation is under “How this chart was made” on the chart's page. The calculations are done by code that is tested against figures read directly from SSB's tables.

Missing and confidential values are never shown as zero. If a figure is missing, it says so.

How we choose figures

These rules decide which topics we take up:

• The topic answers a question many people have, judged by news coverage and by what people search for.
• SSB publishes figures that answer it, without our needing data SSB does not make open.
• The figures can be explained honestly in a few sentences. If the honest explanation is “it is complicated”, the story says so or is not made.
• Topics are not chosen or avoided to support a political position. Where a topic is contested, we show the figures most relevant to the question, say what they do not show, and link to SSB's own description.

What the figures do not show

• The figures describe, they do not explain. We do not write that one thing is due to another unless the table shows it.
• The latest year's figures may be provisional. SSB revises them.
• Prices and pay are in current kroner unless stated. When a chart shows development adjusted for inflation, it says so and how it was done.
• SSB rounds small numbers to protect privacy, and small municipalities swing a lot from year to year.
• On maps the colour shows the order of the municipalities, in five equally sized groups, not how large the differences are. Maps show rates and shares, never counts.

Maps

The municipal boundaries are from Kartverket (Administrative units, municipalities, reference date 1 January 2026, CC BY 4.0), simplified for drawing. They contain no figures.

Accessibility

Every chart has a text description with the figures and a table you can open, and works without JavaScript and on a phone. The aim is WCAG 2.2 AA. We check automatically and by eye, but have not had an external audit.

Versions

Embedded charts can follow the figures or be fixed to one publication. Fixed versions never change, except that a correction may be added. See Embed guide and Corrections.
