12.8% of the 36,227 sites we tried to scan across 12 cohorts in the United Kingdom refused the census scanner.

Sites
4,652 of 36,227 sites we tried to scan
Group
United Kingdom, 12 cohorts pooled
Distinct addresses
29,355 (a site on two rosters is two entries)
Edition
Census Q4 2026, Index 12.1, computed 2026-11-06
Caveat
Public rosters, not a random sample of the web; a site on more than one roster counts once in each, and says nothing about sites outside the United Kingdom.
