The Gallup Poll

This work is the only complete compilation of polls taken by the Gallup Organization, the world's most reliable and widely quoted research firm, in calendar year 2015. It is an invaluable tool for ascertaining the pulse of American public opinion as it evolves over the course of a given year, and—over time—documents changing public perceptions of crucial political, economic, and societal issues. It is a necessity for any social science research.
