News coverage is heavily weighted toward male sources even in countries such as the UK and Australia where gender equality ratings are relatively high. Overall, women are only interviewed or cited in 30 per cent of TV news stories in the ten nations.
In all ten countries, female sources tend only to appear in longer news items or articles and are preferred for soft news topics such as family, lifestyle and culture.
