Our vision
Following the data
Our paper Following the money tried to understand how transparent think tanks are and how the public views them. This paper therefore included a wide range of data, individual responses from think tanks and polling. The polling was conducted by Deltapoll and our polling partner was the Millbank Think Tank whilst the rest of this data was collected by Centre Think Tank.
Think tanks made a total of
in their latest statement or annual report, mostly from 2022. This includes think tanks and organisations which have some of the same roles.
Income transparency
Our main rankings were based on levels of income transparency. Income transparency is where an orginisation releases the individuals or organisations that fund them. An A* rating means all income sources are available, A means all income sources over £7,500 are listed by exact amounts, B means all income sources over £7,500 are listed in bands, C means some income sources are listed, and D means we were unable to find any income sources or amounts. You can see the full methodology in the paper.

Polling views on think tank transparency
Our polling partners Millbank commissioned Deltapoll to ask the public about their views on think tank transparency. Centre wrote the original question and analysed the results. The poll includes the answers of 1,036 adults from Great Britain and the poll was conducted between the 19th to the 20th October 2023.
The question we asked was “As you may know, there are several ‘think tanks’ in the UK which are mostly funded by donations from various sources. The donations are used to help design and promote political policies which could be implemented by any government of the day”. It then asks “From what you may have seen or heard, when it comes to how think tanks receive and spend their money do you think they are…” and then listed four options which were: “Very transparent about how they raise and spend their money”, “Quite transparent”, “Not very transparent”, “Not at all transparent about how they raise and spend their money Don’t know”.
The overall result was clear, the public do not view think tanks as transparent. It was a view shared by every sub group in the poll regardless of region, age, political leaning, employment status, sex, voting intention, social class, how they voted in the referendum and whether they were in a red wall seat.
