Advertisers are over-representing black people in TV commercials while pensioners and the disabled are being forgotten, research has found.

Channel 4's Mirror on the Industry study discovered that despite diversity in adverts improving, some minorities are rarely featured.

The analysis was carried out by the agency Tapestry which audited the top 500 adverts shown across all stations over two four-week periods.

It found that more than half of the commercials featured black people. According to the 2021 census, four per cent of the population of England and Wales is black.

However, the representation of disabled, elderly and pregnant people was lagging behind that for people of colour.
