Census Q4 2026: United Kingdom

43,585 organizations · 31,156 scanned · Index 12.1, in effect 2026-10-21 · generated 2026-11-06

Complete, with gaps

31,156 of 43,585 organizations returned a score.

The run is finished. The other 419 refused the scanner, timed out, or failed outright, and no further attempt is coming. Every share below is out of what was actually scanned, never out of the cohort size. That a site cannot be read at all is itself a result.

Who was scanned

The United Kingdom census, by kind of organization

Each is measured on its own, and none is added to another: a figure across them would describe whichever has the most sites.

Government

Government, by level

Every government site in the Census as one figure, with the same sites split by the level of government beneath it. A site with no website on record, one we could not reach and one that turned us away are counted in the first column and never in a median.

What gated means

Gated means a site failed RCH-1 or RCH-2: it blocks AI crawlers outright, so nothing else about it can be reached. The score is capped rather than averaged away, because a site nothing can read is not partly ready.

Where the failures are

The tests almost nobody passes

The share is out of the sites each test actually applied to. A test that was N/A for a site isn’t counted against it, and the count is shown so a share with a small denominator can’t masquerade as a sector finding.

The data

The data, and how to license it

Every site row carries the SHA-256 of the result behind its score, recorded when the scan finished rather than computed now, so a number on this page traces to a file, and that file to a run.

FileWhat is in it
summary.json The headline figures on these pages, including the band distributions and the N/A reasons the tables above summarize. It holds nothing about a named site.
