Public Policy Research Think Tanks 2019: Top Think Tanks - Worldwide (US and non-US)

Brookings Institution – Worldwide (U.S. and non-U.S.) Center of Excellence for 2016-2018

Note that the 2019 Global Go To Think Tank Report has a change from previous indexes. Any think tank that has ranked as the top think tank in a category for three consecutive years will not be included in the ranking list for the next three years; instead, it will be given a unique distinction: "Think Tank Center of Excellence." This year, the Brookings Institution (U.S.) received this distinction. Read more about this new classification on page 57 of the 2019 Global Go To Think Tank Report.
