These graphs reflect the results from Transparify’s 2016 report. Transparify rates the extent to which think tanks publicly disclose where their funding comes from:
We visited think tanks’ websites and looked at the funding and donor information disclosed online, including in online annual reports.
Institutions rated with five stars are highly transparent about who funds them. On the opposite end of the spectrum, think tanks rated with one or no stars are highly opaque about who funds them, and fail to disclose the names of some or all of their donors.
The results are grouped by region, and rate 200 think tanks in over 47 countries around the world.
