Over the past five years, we have been building the most comprehensive picture of diversity in UK television production ever compiled - and publishing it for you to see and act upon. Diamond monitors the long-term impact of our actions, so join us in looking at the data to see how the industry has changed, has not changed, and could change in the future. In this fifth year of data collection, we have accumulated over 41,000 diversity forms relating to more than 850,000 TV production contributions.
