18.9% of the 43,271 sites we tried to scan across 16 cohorts in the United States refused the census scanner.

Sites
8,173 of 43,271 sites we tried to scan
Group
United States, 16 cohorts pooled
Distinct addresses
32,758 (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 States.
