Experts from the British public broadcaster BBC assume that fewer than a billion people worldwide watched Queen Elizabeth II's state funeral on television. They did not want to commit to an exact number due to a lack of data. But the estimate of 4.1 billion people, more than half of the world's population, given by many news websites in the run-up to the funeral, is probably far too high.

"Below a billion seems more likely, but I wouldn't give a number because there just isn't enough data," BBC expert Charlotte McDonald said on Wednesday's radio show More or Less.

As a result, with around 29 million viewers, even in Great Britain less than half (43 percent) of the population tuned in. In other Commonwealth countries there were fewer. In Canada, with around 13.2 million people, just over a third and in Australia with around 5.2 million people, a fifth of the population sat in front of the television. In the USA, the major event drew around 11.4 spectators in front of the screens. This corresponds to around three percent of the population.

According to the BBC, no or only very vague figures are available for countries such as China and India as well as many African countries. But it is considered unlikely that the proportion of viewers there is higher than in countries where the head of state was the Queen.
