Gallup Poll Social Series (GPSS)

  • The Gallup Poll Social Series (GPSS) is a set of public opinion surveys designed to monitor U.S. adults' views on numerous social, economic, and political topics. The topics are arranged thematically across 12 surveys. Gallup administers these surveys during the same month every year and includes the survey's core trend questions in the same order each administration. Using this consistent standard allows for unprecedented analysis of changes in trend data that are not susceptible to question order bias and seasonal effects.
  • Columbia currently has the February survey about world affairs, the March survey about Environment, the April survey about Economy and Finance, and the June survey about Minority Relations. Gallup also collected a similar dataset about Minority Relations in 2018. For patrons who need surveys of the other months, contact with the Research Data Services (data@library.columbia.edu) please.
