The Brookings Institution is an American think tank based on Embassy Row in Washington, D.C., USA. One of Washington's oldest think tanks, Brookings conducts research and education in the social sciences, primarily in economics, metropolitan policy, governance, foreign policy, and global economy and development. In the University of Pennsylvania's 2014 Global Go To Think Tanks Report, Brookings is ranked the most influential think tank in the world. Its stated mission is to "provide innovative and practical recommendations that advance three broad goals: strengthen American democracy; foster the economic and social welfare, security and opportunity of all Americans; and secure a more open, safe, prosperous, and cooperative international system". Brookings states that its staff "represent diverse points of view" and describes itself as non-partisan, while the media most frequently describe Brookings as "liberal-centrist" or "centrist". An academic analysis of Congressional records from 1993 to 2002 found that Brookings was referenced by conservative politicians almost as frequently as liberal politicians, earning a score of 53 on a 1â€“100 scale with 100 representing the most liberal score. The same study found Brookings to be the most frequently cited think tank by the U.S. media and politicians.
