Content
Generally, the PollingReport contains published reports of national, state and regional surveys of a political and social nature from several dozen main sources. Though trended data released by survey firms may provide historical background, typically the polls posted on the PollingReport date only from 1998. The iPOLL system focuses on national scope surveys and contains not only the complete question text and responses to half a million questions from as far back as 1935, but also information such as study abstracts, links to questionnaires, datasets and citation information where available.
