An estimate of how many people are watching YouTube at the same moment in each country, on any screen: phones, computers, tablets and TVs. It counts people, not devices or monthly users.
Modelled, not measured: YouTube does not publish live viewer counts. Each figure is YouTube users in that country (Google's ad-reach figures, late 2025, via DataReportal) × about 80 minutes of viewing per person per day, spread over the day by a typical hourly viewing pattern.
Recalculated at 03:00 and 15:00 UTC, the two daily viewing peaks across these countries. Read the figures as an order of magnitude, not an exact count.
