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. This data will then be available for one year. Longer periods of access are not typically funded; however, the library may consider renewals on a case-by-case basis, depending on expressed need, available funding, and broader interest by the university.
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.)

Overview
Datasets & Statistics - What's the Difference?
The following is an example of a data set as it appears in a statistical software program. It is presented with all available variables in one file. The user can manipulate, aggregate and create descriptive statistics as needed.
Below is a visualization of the data set as statistics (percent of families receiving Temporary Cash Assistance [TANF] by neighborhood). Statistics are presented in an aggregate form already. This could be a table of frequencies, means, rates, charts or graphs. Statistics are information based on previously collected and analyzed data on which conclusions are drawn.
Which should I use?
When you want to strengthen a point for a presentation or paper, you would typically use available statistics or you might create your own (there are many table building tools available). If you're planning to test a hypothesis, develop a comprehensive marketing strategy, assess the effect of a particular treatment - or anything that would require in-depth analysis - then you need a dataset. Make sure that if you are using existing data or statistics (content that you didn't personally collect or analyze), that you check the authenticity of your sources and that you cite them according to proper conventions for your area of study.
About this guide
This guide is designed to help you find both statistics and datasets. Some of the resources provided are limited to the Johns Hopkins domain and will require you to log in with your JHED ID and password in order to use them. However, many data sources that are available from government agencies, think tanks, non-profits, etc. are open access. This guide is not exhaustive, but designed to provide you with a solid starting point on possible sources. If you are not finding what you are looking for, please email me for assistance (see the box on the left).
Access to Content
If you are on the Johns Hopkins "guest" wireless networks (on both Homewood and JHMI campuses) you will NOT always be able to view full content of subscribed databases unless you use the Virtual Private Network (VPN).

Data Citation Index - Web of ScienceDiscover research datasets across a wide range of disciplines within the social sciences, sciences and humanities. None of the data is housed within the index, but links to data repositories are provided. Results are returned at the individual dataset with links to the data study. Like the rest of the Web of Science citation databases, you will be able to track dataset and data study citations within research literature.
