How are iPOLL search results ordered? It appears the results are sorted by "newest" first but there are some exceptions.

iPOLL search results are sorted by the most recent "Beginning Field Date" therefore on occasion you may see something seemingly out of order.

What is the difference between a survey's "Field Dates," "Release Date" and "Posted Date?"

"Field Dates" reflect the dates on which the survey was undertaken by the survey organization. "Release Date" is the date the survey organization made the results available to the public. "Posted Date" is the date the survey was entered into the iPOLL Databank.

How do I properly cite the data I use from the Roper Center?

Publications based on Roper Center data collections should acknowledge the Roper Center and the organization(s) that originally sponsored and collected the data. Click here for more information on how to cite our data.

How do I access Roper Center resources when I am off-campus?

Member university faculty and students may access Roper Center resources while off campus by logging into the proxy server or Virtual Private Network (VPN) typically available through your university library.

Does iPOLL include the results of internet surveys?

Typically internet surveys are not included in iPOLL, though several studies have been included as part of larger collections such as CBS News Polls. The methodology involved in internet polling is still a subject of contentious debate among survey professionals. We do have the results of some Internet surveys at the Roper Center, but they are not at present entered into the iPOLL database on a regular basis. (See Statement About Internet Polls by NCPP Polling Review Board.)

How does iPOLL enhance my membership?

Like Search for Datasets, iPOLL can help you identify U.S. datasets that are rich in specific subject areas. However, because iPOLL provides the text and topline responses for all the questions, it makes selecting datasets easier and offers an appropriate context in which to review data, by comparing various questions and sources on the same topic and trend lines. Questions in iPOLL are linked to the Catalog study descriptions and often the questionnaires.

What is the difference between searching iPOLL and searching for datasets?

The Search for Datasets includes only those surveys for which the Roper Center holds the datasets (microdata or individual level), with brief descriptions of each. These include national, state, and foreign surveys, as well as special samples such as leaders or youth. iPOLL contains the aggregated question-level results from the US national surveys in the catalog, as well as a great deal of additional survey data from news releases and survey reports.

How do I get all of the questions and responses from one survey?

To retrieve all questions from an entire survey, regardless of when the questions were published, simply search for the survey organization using the organization pull-down menu and the beginning interview date using the date boxes on the search form. It is important to note that the date criteria used on the search form searches on the FIRST date of the interview period.

What kinds of surveys are included in iPOLL?

iPOLL includes data survey results from academic, commercial and media survey organizations such as ABC News, the Gallup Organization, Pew Research Centers, Kaiser Family Foundation, and many more. The data come from all the surveys in the Roper Center archive that have US national adult samples or samples of registered voters, women, African Americans, or any subpopulation that constitutes a large segment of the national adult population. iPOLL does not include state samples or foreign samples (see Catalog of Holdings), however, surveys of these populations are available from the Roper Center.

What is iPOLL?

iPOLL is the most comprehensive, up-to-date source for US nationwide public opinion available today. A full-text retrieval system, the iPOLL online database is organized at the question-level. The system allows for users to sift through half a million questions archived from national public opinion surveys since 1935. The database is updated daily.
