What is withheld, and why

Nothing is withheld. Values are served with the attribution the licence asks for: Supported by NGED Open Data. Keep it with any figure you show.

The package is classified Open (dataclassification Open, license_id wpd-open-data, isopen true), and NGED's Open Data Licence applies to data sets marked as provided on an 'Open' basis. The licence page is itself behind the Cloudflare challenge; its text was read from the Wayback Machine capture of 2026-05-08.
