1. These figures cover websites that went live since April 2026, not the web as a whole.
2. Country comes from what each site says about itself, such as a company registration, legal terms or a phone number, not just its domain ending. We count a country only where it is stated plainly enough to be sure: a governing-law clause or company registration number on a legal page, a phone country code, or a country domain ending. Sites that publish none are not counted at all.
