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. Too few sites state their country plainly for the usual count, so this one also counts single signals: a country domain ending, a phone number (for North America, its area code), a location the site declares in its own page metadata, or a country-specific vendor stack and the page language where they agree and nothing contradicts them. Read these as likely rather than certain.
3. Green hosting is the share whose web host The Green Web Foundation lists as running on green energy, among sites checked since 1 April 2026, against the same share for every new site we checked over that time. Data from The Green Web Foundation.
