The Brookings Institution is an American research group founded in 1916 on Think Tank Row in Washington, D.C.[2] It conducts research and education in the social sciences, primarily in economics, metropolitan policy, governance, foreign policy, global economy, and economic development.[3][4] 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."[2]

Brookings has five research programs at its Washington, D.C. campus (Economic Studies,[5] Foreign Policy,[6] Governance Studies,[7] Global Economy and Development,[8] and Metropolitan Policy)[9] and three international centers based in Doha, Qatar (Brookings Doha Center);[10] Beijing, China (Brookings-Tsinghua Center for Public Policy);[11] and New Delhi, India (Brookings India).[12]

The University of Pennsylvania's Global Go To Think Tank Index Report has named Brookings "Think Tank of the Year" and "Top Think Tank in the World" every year since 2008.[13] The Economist describes Brookings as "perhaps America’s most prestigious think-tank".[14]

It is well known that the first two states to vote—Iowa and New Hampshire—differ sharply from the nation on their racial-ethnic attributes. With a white population share of 85% and 90%, respectively (compared to 60.4% for the nation as a whole), they are the sixth and fourth “whitest” states. They also have somewhat older age structures, decidedly less urbanized populations, and a much higher representation of white adults without college educations (“noncollege whites”) than the rest of the nation.

These attributes, interestingly, are more associated with Republican voters than Democratic ones. So Iowa and New Hampshire voters in their Democratic caucus/primary are more likely to be whiter, older, and comprised of more noncollege whites than primary voters in other states, as was the case in the 2016 presidential primaries.
