iPOLL

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.)

What is the difference between iPOLL and other research finding aids?

For a comparison of iPOLL,Polling The Nations and PollingReport.com, please visit iPOLL Comparison.

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. Click here to find out what the difference is between a top-line and a dataset.

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.

What is RoperExpress

RoperExpress is a data access tool for on-demand download of datasets. Faculty and students at Member institutions have unlimited access to those datasets in the Roper Center collection that are in ASCII or SPSS portable formats. Simply conduct a search for datasets and the studies accessible for immediate download in RoperExpress will be marked with an icon: RoperExpress icon.

How can I get the question wordings of all the questions in a given study I find in your Search for Datasets?

You can download the documentation file(s) for a particular study directly from the Search for Datasets survey abstract page, where available. If the study has a US adult sample, iPOLL can provide you the responses to all of the non-demographic questions from the survey. In iPOLL, search for the dates of the poll and using the drop down box, select the name of the organization that conducted the particular poll.

What is the Catalog of Holdings?

The Roper Center archives datasets from thousands of public opinion surveys based on a variety of samples including adult populations of numerous countries and sub-national regions (states, provinces, etc.) as well as as other special populations. These datasets are listed in the Search for Datasets section of the website, which provides a searchable description and unique archive identification number for each survey. Along with such basic information as survey organization, interview dates, and type of sample, most catalog entries include abstracts indicating the subjects covered by the questions in the survey.

For surveys with U.S. national adult or major subpopulation samples (such as registered voters, women, or African Americans), iPOLL can be used as the primary finding aid to locate datasets on particular topics or for specific time periods. For state, foreign, and other special samples, the Search for Datasets tool can be used to locate datasets by keyword (the abstract is searched), date, country, survey organization, survey sponsor, or type of sample.

Once datasets are located, members may use RoperExpress for on-demand download of the data. Faculty and students at Member institutions have unlimited access to those datasets in the Roper Center collection that are in ASCII or SPSS portable formats. Studies accessible for immediate download in RoperExpress are marked with an icon: RoperExpress icon. Non-members can order data from the Roper Center by telephone at (860)486-4440 or by emailing Data Services at DataServices-RoperCenter@uconn.edu with the study name and study number.

RESEARCH

Is the Roper Center the same as the Roper Poll?

There is no connection today between the non-profit Roper Center for Public Opinion Research at the University of Connecticut and the for-profit Roper Poll owned by GfK Group.  Public opinion pioneer Elmo Roper founded both organizations, but they are completely separate entities.

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.

See if your university is currently a member of the Roper Center by visiting List of Members. If you are still unsure of your university's status, call (860)486-4440 or email rcweb@ropercenter.uconn.edu.

I want to conduct a survey of my own. Can the Roper Center help?

You can use iPOLL and documentation to Roper Center data to get ideas about how to ask questions. However, the Roper Center does not conduct surveys or provide detailed advice on survey design.

What formats do you provide data in?

Most datasets from before the 1990s are ASCII ("raw data") format. Many more recent datasets are SPSS portable files. Some older, particularly non-US studies are in column-binary formats. Center staff will convert these to more contemporary formats (ASCII or SPSS) for members upon request.

Can I get information on response rates and sampling procedures?

The documentation for a given survey usually gives basic information on sampling procedures. Working with data contributors, the Center is currently enhancing efforts to provide more complete methodological details. Please contact us for additional information.

How is the Roper Center different from ICPSR?

Both the Roper Center and ICPSR provide access to social science data. The Roper Center focuses on public opinion data primarily collected by commercial and media survey organizations, while ICPSR archives broader based social science data from academic or government sources. Public opinion data is a small portion of the ICPSR collection and overlaps only slightly with the Roper Center's collection of polls.

GENERAL

Is the Roper Center the organization that keeps calling my home?

No, the Roper Center does not conduct surveys.

It's likely that is the firm that is contacting you to complete one of their polls.

Does the Roper Center conduct surveys?

No, the Roper Center does not conduct surveys; it is a library of survey data collected by others who graciously permit the Center to archive and make their findings available to a broader research community.
