Data and Statistics

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

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.)
