Data and Statistics

Learn how to access data and statistics on a variety of topics.

Public Opinion

Pew Research Center
The Pew Research Center is a nonpartisan "fact tank" that provides information on the issues, attitudes and trends shaping America and the world. It does not take positions on policy issues.  See "The Databank" menu or the "Projects of the Center" section to view statistics and download data.

Polling the Nations
A compilation of questions and responses from more than 12,000 national, state, local and special surveys, conducted by 700 polling organizations in the United States and 70 other countries from 1986 through the present. Each record in the database consists of one poll question and the participants answers. Only 4 simultaneous users can access Polling the Nations.

The Roper Center for Public Opinon Research maintains a vast archive of 18,000 public opinion datasets.  The majority of datasets pertain to the U.S. but data from over 50 nations is also represented.  RoperExpress allows you to download the data and documentation directly from the Roper site.  You must register and create an individual account in order to download.

Political

From 1948, the American National Election Studies (ANES) program has produced high quality data on voting, public opinion and political participation. Cumulative, time-series, panel and contextual data are available for download.
Political Risk Services (PRS) provides one of the world's best commercial sources of country risk ratings and forecasts.  Data is available for more than 150 countries, including risk ratings and economic data from International Country Risk Guide, as well as forecasts, economic, political, geographic, and social data from Political Risk Services. CountryData is updated monthly and is the gateway to all current and historical data from The PRS Group.  You are able to download data from your queries as CSV files.

Data Requests via the Data Fund

The Data Fund provides JHU researchers the opportunity to make requests for known datasets that are not readily accessible via the library data subscriptions. Each year, the library is able to provide a small amount of funding to a select number of researchers to facilitate their use of secondary data.

If you have a specific need for secondary proprietary data without security or access restrictions that cannot be obtained by other means please submit a request using the form below for consideration.

Data Fund Purchase Request Form

Please note that submission of the form is not a guarantee of funding. Applicants will receive communication from the data and statistics consultant who will work with the researcher and the academic liaisons within the researcher's discipline to discuss the next steps for the potential use of Data Fund resources to gain access to secondary data. (Undergraduate researchers must have the endorsement of a faculty member to apply. While funds may be made available for undergraduate research projects in special circumstances, the fund's primary mission is to fund data for faculty and graduate student research.)
