Am I thinking wrong in that the viewing figures are obviously going to be “per TV”. So as the Coronation is an opportunity for people to get  together, some households would have around 4 people watching a tv. This would quickly and easily add up to near enough the population.

Then you have to think about the people working on the weekend who would not have had the option to watch a TV.

It's calculated per person, each person on the BARB panel will have registered how many people they were watching with, then the numbers are calculated from there.
