How we verify the data

Statistics get copied from page to page until nobody knows where they came from. These rules keep ours traceable.

Primary sources first

We cite the organisation that measured or published a number, not the article that repeated it.

Dated and re-verified

Each page shows when its figures were last checked against the sources, and we re-check at least once a year.

Claims are labelled

Self-reported surveys, vendor claims and forecasts are marked as such and never mixed with measured data.

Corrections are public

When a number changes or turns out to be wrong, the page says what changed instead of editing it silently.

Use our data

You are welcome to cite any statistic here. Link to the page it came from; each statistics page has a Cite this page panel with ready-made APA, attribution and HTML link snippets. If you find a number that is out of date, email support@signalbridgedata.com and we will check it.
